  • How Long Does It Take to Get PGT Results in Thailand?

    Understanding the PGT Timeline in Thailand

    When undergoing preimplantation genetic testing (PGT) as part of an IVF cycle in Thailand, one of the most common questions is how long it takes to receive results. The timeline involves several steps: embryo biopsy, shipping to a genetics laboratory, testing, and reporting. While exact durations vary by clinic and laboratory, understanding the general process helps you plan your treatment journey.

    At a Glance: Key Steps in the PGT Process

    • Embryo Biopsy: Performed on day 5 or 6 of embryo development (blastocyst stage).
    • Sample Preparation and Shipping: Biopsied cells are prepared and sent to a genetics lab, which may be on-site or off-site.
    • Genetic Testing: The lab performs the specific PGT method (PGT-A, PGT-M, or PGT-SR).
    • Result Reporting: The lab issues a report to your clinic, which then communicates the results to you.

    Step 1: Embryo Biopsy

    Embryo biopsy is typically performed on day 5 or 6 after fertilization, when the embryo has reached the blastocyst stage. A few cells are carefully removed from the trophectoderm (the outer layer that will become the placenta). This step is done at your IVF clinic in Thailand and usually takes a few hours. The biopsied cells are then placed in a special medium for transport.

    Step 2: Shipping to the Genetics Laboratory

    After biopsy, the cell samples must be shipped to a genetics laboratory for testing. Some clinics have an in-house lab, which can shorten the timeline. Others send samples to a partner laboratory, which may be located in Thailand or abroad. Shipping typically takes 1–3 days, depending on the location and courier service. Samples are shipped in temperature-controlled containers to maintain viability.

    Step 3: Genetic Testing

    The testing phase is the longest part of the process. The duration depends on the type of PGT:

    • PGT-A (aneuploidy screening): Tests for chromosomal abnormalities. Results may be available within 7–14 days.
    • PGT-M (monogenic disorders): Tests for specific genetic conditions. This requires a customized test and may take 4–8 weeks or longer, depending on the complexity.
    • PGT-SR (structural rearrangements): Tests for chromosomal structural changes. Timeline is similar to PGT-A, often 7–14 days.

    These timeframes are estimates; confirm with your clinic and laboratory for their specific turnaround times.

    Step 4: Result Reporting

    Once testing is complete, the genetics laboratory issues a report to your IVF clinic. The clinic then reviews the results and schedules a consultation to discuss them with you. This step usually takes a few days to a week. In some cases, results may be available sooner if the clinic has a direct electronic link with the lab.

    Factors That Influence the Timeline

    • Laboratory location: On-site labs are faster than off-site or international labs.
    • Type of PGT: PGT-M requires custom test development, adding weeks to the timeline.
    • Number of embryos: Testing more embryos may take slightly longer, but labs often batch process.
    • Clinic and lab protocols: Each clinic and lab has its own standard operating procedures.
    • Shipping and customs: International shipping may be subject to customs clearance, adding delays.

    Questions to Ask Your Clinic

    • Do you have an on-site genetics laboratory, or do you send samples to an external lab?
    • What is the typical turnaround time for PGT-A, PGT-M, and PGT-SR results?
    • How will I receive the results (phone, email, in-person consultation)?
    • Are there any factors that could delay results (e.g., holidays, shipping issues)?
    • Can I choose to freeze embryos and wait for results before a frozen embryo transfer (FET)?

    Next Steps After Receiving Results

    Once you have your PGT results, your clinic will help you interpret them and plan the next steps. If you have viable embryos, you may proceed with a frozen embryo transfer (FET) in a subsequent cycle. If no viable embryos are available, your doctor will discuss alternative options, such as a new IVF cycle or using donor gametes.

    Important Considerations

    PGT is a screening tool, not a guarantee of a healthy pregnancy or live birth. It can reduce the risk of transferring embryos with certain genetic abnormalities, but it does not eliminate all risks. Discuss the limitations and benefits with your fertility specialist to make an informed decision.

    For more information, explore our PGT in Thailand guide, other fertility guides, and frequently asked questions.

    Frequently asked questions

    How long does PGT-A testing take in Thailand?

    PGT-A testing typically takes 7–14 days after the biopsy sample reaches the genetics laboratory. However, the total timeline from biopsy to result reporting may be longer due to shipping and clinic processing. Confirm exact turnaround times with your clinic.

    Does PGT-M take longer than PGT-A?

    Yes, PGT-M usually takes longer because it requires developing a customized test for the specific genetic condition. This can add several weeks to the timeline, often 4–8 weeks or more. Discuss the expected timeline with your clinic and genetics lab.

    Can I get PGT results faster if the lab is on-site?

    An on-site genetics laboratory can reduce the time needed for shipping and sample handling, potentially shortening the overall timeline. However, the testing duration itself depends on the type of PGT and the lab's protocols. Ask your clinic if they have an in-house lab.

    What happens if PGT results are delayed?

    Delays can occur due to shipping issues, laboratory backlogs, or the need for repeat testing. Your clinic should keep you informed of any delays. In most cases, embryos are frozen and stored until results are available, so a delay does not affect embryo viability.

    Do I need to stay in Thailand while waiting for PGT results?

    Not necessarily. Many patients return home after the embryo biopsy and receive results remotely. However, if you plan to proceed with a frozen embryo transfer immediately after results, you may need to return to Thailand. Discuss your travel plans with your clinic.

  • How Long Does PGT Take in Thailand? A Timeline for IVF Patients

    Understanding the PGT Timeline in Thailand

    When planning IVF with preimplantation genetic testing (PGT) in Thailand, one of the most common questions is how long the entire process takes. The answer depends on several factors, including the type of PGT, the laboratory’s workflow, and shipping logistics. This guide provides a general overview of the timeline so you can plan your travel and schedule accordingly. Remember that each clinic and lab may have slightly different procedures, so always confirm specific timelines with your treating clinic.

    At a Glance: Key Steps in the PGT Timeline

    • Embryo Biopsy: Performed on day 5 or 6 after egg retrieval, when embryos reach the blastocyst stage.
    • Biopsy Shipping: Biopsied cells are prepared and shipped to a genetics laboratory, which may take 1–2 days.
    • Genetic Testing: The lab performs DNA amplification and analysis. Turnaround time varies by test type (PGT-A, PGT-M, PGT-SR).
    • Results Reporting: Results are sent to your clinic, which then shares them with you. This can take additional 1–2 days for review.
    • Total Time: From biopsy to final results, the process typically spans 2–4 weeks, but this can vary.

    Step 1: Embryo Biopsy (Day 5–6)

    After egg retrieval and fertilization, embryos are cultured in the lab until they reach the blastocyst stage, usually on day 5 or 6. At this point, a few cells are gently removed from the trophectoderm (the part that becomes the placenta) for genetic testing. The biopsy itself takes only a few minutes, but the embryo must be of sufficient quality to undergo the procedure. Your clinic will schedule the biopsy based on embryo development.

    Step 2: Shipping Biopsied Cells to the Genetics Lab

    Once the biopsy is complete, the cell samples are placed in a special medium and shipped to a genetics laboratory. If the lab is located within Thailand, shipping may take just 1 day. If samples are sent to an international lab (common for specialized tests like PGT-M), shipping can take 2–3 days depending on courier services and customs clearance. Some clinics have on-site genetics labs, which can reduce shipping time to zero.

    Step 3: Genetic Testing (Variable Duration)

    The actual testing time depends on the type of PGT:

    • PGT-A (aneuploidy screening): Typically the fastest, with results in 7–14 days.
    • PGT-M (monogenic disorders): Requires a customized probe or test development, which can take several weeks to months before the cycle even starts. After biopsy, results may take 2–4 weeks.
    • PGT-SR (structural rearrangements): Similar timeline to PGT-A, often 10–14 days.

    These are general estimates; actual turnaround times depend on the lab’s workload and the complexity of the test. Some labs offer expedited services for an additional fee.

    Step 4: Receiving and Reviewing Results

    After the genetics lab completes the analysis, results are sent to your clinic. The clinic’s embryologist and genetic counselor will review the report and prepare a summary for you. This step usually takes 1–2 days. You will then have a consultation with your doctor to discuss which embryos are suitable for transfer.

    Factors That Can Affect the Timeline

    • Lab location and logistics: International shipping adds time and potential delays (e.g., customs, holidays).
    • Type of PGT: PGT-M requires pre-cycle probe development, extending the overall timeline by weeks or months.
    • Embryo development: Not all embryos reach blastocyst stage on day 5; some may be biopsied on day 6 or 7, shifting the schedule.
    • Lab capacity: Busy periods may slow down testing.
    • Clinic protocols: Some clinics batch biopsies or send samples on specific days, adding waiting time.

    Questions to Ask Your Clinic

    To get a personalized timeline, ask your clinic the following:

    • Which genetics laboratory do you work with, and where is it located?
    • What is the typical turnaround time for the specific PGT test I need?
    • Do you offer expedited testing, and what is the cost?
    • How are biopsy samples shipped, and how long does shipping usually take?
    • When will I receive the results, and how will they be communicated?

    Planning Your Travel and Stay

    Since the PGT process takes several weeks after egg retrieval, many international patients plan to stay in Thailand for at least 3–4 weeks to cover the biopsy and initial waiting period. However, you may be able to return home after the biopsy and receive results remotely. Discuss with your clinic whether a follow-up visit is needed for embryo transfer, which typically occurs in a subsequent menstrual cycle after results are available.

    Next Steps

    • Confirm the PGT timeline with your chosen clinic during your initial consultation.
    • Ask about the possibility of remote result disclosure and virtual consultations.
    • Plan your travel itinerary with buffer days to accommodate any delays.
    • Check with the genetics lab about any additional requirements for sample shipping.

    Frequently asked questions

    How long does PGT-A take in Thailand?

    PGT-A (aneuploidy screening) typically takes 7–14 days from the time the biopsy sample reaches the genetics lab. Including shipping and result reporting, the total time from biopsy to receiving results is usually 2–3 weeks.

    Does PGT-M take longer than PGT-A?

    Yes, PGT-M (for monogenic disorders) often requires a customized test development before the cycle, which can take several weeks to months. After biopsy, the testing itself may take 2–4 weeks, so the overall timeline is longer.

    Can I leave Thailand while waiting for PGT results?

    Many patients choose to return home after the biopsy and receive results remotely. However, you should confirm with your clinic whether a follow-up visit is needed for embryo transfer, which is usually scheduled in a later cycle.

    What factors can delay PGT results?

    Delays can occur due to shipping issues (e.g., customs, holidays), lab workload, or the need for repeat biopsy if the initial sample is insufficient. Your clinic can provide the most accurate estimate based on current conditions.

  • PGT Results Timeline from a Thai Lab: What to Expect

    Understanding the PGT Process and Timeline

    Preimplantation genetic testing (PGT) is performed on embryos created through IVF to screen for genetic abnormalities. The timeline from embryo biopsy to receiving results involves several steps, each with its own duration. While exact turnaround times vary by lab, a general understanding helps patients plan their cycle and travel.

    At a Glance: Key Steps in PGT

    • Embryo Biopsy: Cells are removed from the embryo on day 5 or 6 of development.
    • Sample Preparation and Shipping: Biopsied cells are prepared and sent to the genetic testing laboratory.
    • Genetic Analysis: The lab performs DNA amplification and analysis (e.g., next-generation sequencing).
    • Result Reporting: Results are sent to the IVF clinic, which then communicates them to you.

    Typical Timeline for PGT Results

    The entire process from biopsy to results generally takes between 7 to 14 days. However, this can vary based on the lab’s workload, the type of PGT (PGT-A for aneuploidy, PGT-M for monogenic disorders, PGT-SR for structural rearrangements), and logistical factors. Below is a general breakdown:

    Step Approximate Duration Notes
    Embryo biopsy Day 5–6 of embryo development Performed at the IVF clinic
    Sample shipping to lab 1–2 days Domestic or international courier
    DNA amplification and analysis 5–10 days Depends on lab protocol and test type
    Result reporting to clinic 1–2 days Electronic report
    Clinic communication to patient 1–2 days May include consultation

    Total: Approximately 7–14 days from biopsy to patient notification.

    Factors That Can Affect the Timeline

    Type of PGT

    PGT-A (aneuploidy screening) is typically faster than PGT-M or PGT-SR, which require additional steps such as developing a customized probe or analyzing specific gene mutations.

    Lab Workload and Scheduling

    Genetic testing labs may have varying workloads. Some labs run batches on specific days, which can introduce delays. Confirm with your clinic whether the lab processes samples continuously or in batches.

    Shipping and Logistics

    If the lab is located outside Thailand, international shipping and customs clearance can add time. Even domestic shipping may be affected by courier schedules.

    Sample Quality

    Rarely, a biopsy sample may have insufficient cells or poor DNA quality, requiring a repeat biopsy or additional analysis, which extends the timeline.

    Clinic Communication

    Some clinics wait until all results are ready before notifying patients, while others provide results as they become available. Ask your clinic about their policy.

    Planning Your IVF Cycle and Travel

    Since PGT results are needed before a frozen embryo transfer (FET), the timeline affects your overall cycle planning. Typically, after egg retrieval and fertilization, embryos are cultured to day 5–6 for biopsy. The results arrive about 1–2 weeks later. If you are traveling to Thailand for treatment, consider the following:

    • Duration of stay: You may need to stay for the initial IVF phase (egg retrieval, fertilization, biopsy) and then return for FET after results are available. Alternatively, some patients remain in Thailand during the waiting period.
    • Embryo freezing: After biopsy, embryos are vitrified (frozen) and stored until results are ready. This is standard practice.
    • FET scheduling: Once results are received, you can plan the FET cycle, which typically involves hormonal preparation over 2–4 weeks before transfer.

    Discuss with your clinic the expected timeline and whether you can receive results remotely or need to be present for consultation.

    Questions to Ask Your Clinic

    • Which genetic testing lab do you work with, and where is it located?
    • What is the typical turnaround time for PGT results from that lab?
    • Do you batch samples, or are they processed individually?
    • How will I receive the results (phone, email, portal)?
    • Can I have a consultation to discuss results remotely?
    • What happens if the sample is insufficient or results are delayed?

    Next Steps

    • Confirm the PGT timeline with your chosen IVF clinic in Thailand.
    • Plan your travel and accommodation to accommodate the waiting period.
    • Discuss embryo storage and shipping options if you plan to transfer embryos to another location.
    • Ensure you have a clear understanding of costs associated with PGT and any potential additional charges for rush processing or repeat biopsies.

    Frequently asked questions

    How long does PGT-A take in Thailand?

    PGT-A typically takes about 7–10 days from biopsy to results, but this can vary by lab. Confirm the exact timeline with your clinic.

    Can I get PGT results faster if I pay extra?

    Some labs offer expedited processing for an additional fee. Ask your clinic if this option is available and how much time it saves.

    What happens if my embryo biopsy sample is insufficient?

    If the sample has too few cells or poor DNA, the lab may request a repeat biopsy from the same embryo (if possible) or the result may be inconclusive. This can add several days to the timeline.

    Do I need to stay in Thailand while waiting for PGT results?

    Not necessarily. Many patients return home after the biopsy and receive results remotely. However, you will need to return for the frozen embryo transfer, which is typically scheduled after results are available.

    How long after PGT results can I have the embryo transfer?

    The transfer is usually scheduled during a subsequent menstrual cycle, after hormonal preparation of the uterine lining. This can take 2–4 weeks from the start of the cycle.

  • Can PGT Detect Mitochondrial Disorders in Thailand?

    Understanding PGT and Mitochondrial Disorders

    Preimplantation genetic testing (PGT) is a technique used during in vitro fertilization (IVF) to screen embryos for genetic abnormalities. However, its ability to detect mitochondrial disorders—caused by mutations in mitochondrial DNA (mtDNA)—is limited. This is due to the unique biology of mitochondria, including heteroplasmy (the presence of both normal and mutated mtDNA within a cell) and the random distribution of mitochondria during cell division.

    In Thailand, PGT is available at several fertility centers, but patients with mitochondrial disease concerns should understand what PGT can and cannot do, and what alternative options exist.

    At a Glance: Key Points

    • PGT-A (aneuploidy screening) does not detect mtDNA mutations.
    • PGT-M can be designed for specific nuclear gene mutations but has limited accuracy for mtDNA disorders.
    • Mitochondrial replacement therapy (MRT) is not legally available in Thailand.
    • Genetic counseling and pre-conception carrier screening are important first steps.

    Types of PGT and Their Relevance to Mitochondrial Disorders

    PGT-A (Aneuploidy Screening)

    PGT-A checks embryos for extra or missing chromosomes. It does not analyze mtDNA and cannot detect mitochondrial mutations.

    PGT-M (Monogenic Disorders)

    PGT-M is designed for single-gene disorders. For mitochondrial disorders caused by nuclear DNA mutations (e.g., some forms of Leigh syndrome), PGT-M can be effective. However, for mtDNA mutations, PGT-M is less reliable due to heteroplasmy and the difficulty of quantifying mutation load in a single cell biopsy.

    PGT-SR (Structural Rearrangements)

    PGT-SR detects chromosomal structural changes. It is not relevant for mtDNA disorders.

    Limitations of PGT for mtDNA Disorders

    • Heteroplasmy variability: The proportion of mutated mtDNA can differ between cells of the same embryo, and a biopsy of a few cells may not represent the whole embryo.
    • Threshold effect: Symptoms often appear only when mutation load exceeds a certain threshold, which is difficult to predict from embryo testing.
    • Mosaicism: mtDNA mutations can be unevenly distributed, leading to false negatives or positives.
    • Technical challenges: Accurate quantification of mtDNA heteroplasmy from a trophectoderm biopsy is not yet standardized.

    Alternative Options for Patients with Mitochondrial Disease Concerns

    Pre-conception Carrier Screening

    Both partners can undergo genetic testing to identify carrier status for nuclear gene mutations that cause mitochondrial disorders. This helps assess recurrence risk.

    Prenatal Diagnosis

    During pregnancy, chorionic villus sampling (CVS) or amniocentesis can test fetal cells for mtDNA mutations. However, these procedures carry a small risk of miscarriage and may not fully predict postnatal severity.

    Donor Egg or Embryo

    Using an egg or embryo from a donor with healthy mitochondria can eliminate the risk of passing on mtDNA mutations. This is a widely available option in Thailand.

    Mitochondrial Replacement Therapy (MRT)

    MRT, also known as “three-parent IVF,” involves replacing faulty mitochondria in the egg with healthy mitochondria from a donor. This technique is not currently permitted in Thailand. Patients interested in MRT would need to explore legal options in other countries.

    Questions to Ask Your Clinic

    • Does your lab offer PGT-M for mitochondrial disorders? If so, what is the protocol for mtDNA mutation detection?
    • How do you handle heteroplasmy assessment in embryo biopsies?
    • What are the limitations of PGT for my specific mitochondrial mutation?
    • Do you offer genetic counseling for mitochondrial disorders?
    • What alternative options (e.g., donor egg) are available?

    Next Steps

    1. Consult with a genetic counselor to understand your specific mutation and inheritance pattern.
    2. Discuss with your fertility clinic whether PGT-M is feasible for your case.
    3. Consider pre-conception carrier screening for both partners.
    4. Explore donor options if PGT is not suitable.

    For more information, see our PGT in Thailand guide, other guides, and FAQ.

    Frequently asked questions

    Can PGT-A detect mitochondrial disorders?

    No, PGT-A screens for chromosomal aneuploidies and does not analyze mitochondrial DNA. It cannot detect mtDNA mutations.

    Is PGT-M reliable for mitochondrial DNA mutations?

    PGT-M has limited reliability for mtDNA mutations due to heteroplasmy and technical challenges. It may be more effective for nuclear gene mutations causing mitochondrial disorders.

    What is the alternative if PGT cannot detect my mitochondrial disorder?

    Options include pre-conception carrier screening, prenatal diagnosis, or using a donor egg or embryo. Mitochondrial replacement therapy is not available in Thailand.

    Does Thailand allow mitochondrial replacement therapy (MRT)?

    No, MRT is not currently permitted in Thailand. Patients interested in this option would need to seek treatment in countries where it is legal.

  • PGT-A for Mosaic Embryos in Thailand: Retesting Options and Lab Practices

    Understanding Mosaic Embryos and PGT-A

    Preimplantation Genetic Testing for Aneuploidy (PGT-A) screens embryos for chromosomal abnormalities. A mosaic embryo contains a mix of normal and abnormal cells. The degree of mosaicism (low, medium, high) influences how the embryo is classified and whether it may be considered for transfer.

    If you have a mosaic embryo from a previous cycle, you may wonder whether Thai clinics can retest it or offer alternative options. This article explains how Thai labs typically handle mosaic embryos and what steps you can take.

    How Thai Labs Classify Mosaic Embryos

    Thai IVF laboratories generally follow international guidelines for mosaicism classification. Mosaic embryos are often categorized as:

    • Low-level mosaicism (20-40% abnormal cells)
    • Medium-level mosaicism (40-60% abnormal cells)
    • High-level mosaicism (60-80% abnormal cells)

    Classification may vary by lab, so it is important to ask your clinic about their specific criteria. Some labs may also use terms like “aneuploid” or “euploid” with a mosaic comment.

    Retesting Options for Mosaic Embryos

    Retesting a mosaic embryo is possible in some cases, but it depends on the embryo’s quality and the lab’s protocols. Options may include:

    • Thaw and re-biopsy: The embryo is thawed, a new cell sample is taken, and PGT-A is repeated. This carries risks of damage to the embryo.
    • Transfer without retesting: Some clinics may offer transfer of low-level mosaic embryos after counseling, as they can sometimes result in healthy pregnancies.
    • Additional testing: Some labs may offer extended culture or other techniques to clarify mosaicism, but availability varies.

    Not all Thai clinics offer retesting for mosaic embryos. Confirm directly with the clinic whether they perform re-biopsy and what their success rates are for thawed embryos.

    Questions to Ask Your Thai Clinic

    Before deciding on retesting or transfer, consider asking the following questions:

    • What is your lab’s classification system for mosaic embryos?
    • Do you offer re-biopsy and retesting for mosaic embryos? If so, what is the survival rate after thaw?
    • What are your criteria for considering a mosaic embryo for transfer?
    • Do you provide genetic counseling to discuss the risks and outcomes of mosaic embryo transfer?
    • Can you coordinate with my previous clinic to obtain the original biopsy sample or results?

    Alternatives to Retesting

    If retesting is not possible or not recommended, alternatives may include:

    • Starting a new cycle: Creating new embryos and testing them with PGT-A may yield euploid embryos for transfer.
    • Using donor embryos: Some patients opt for donated embryos that have been tested and confirmed euploid.
    • Transferring the mosaic embryo: After thorough counseling, some patients choose to transfer a low-level mosaic embryo, understanding the potential risks.

    Each option has its own considerations. Discuss with your fertility specialist and genetic counselor to determine the best path for your situation.

    Key Takeaways

    • Thai labs classify mosaic embryos based on the percentage of abnormal cells, but criteria may differ.
    • Retesting via re-biopsy is possible in some clinics but carries risks and is not universally offered.
    • Transfer of low-level mosaic embryos may be an option after genetic counseling.
    • Always confirm specific lab protocols, success rates, and costs directly with the clinic.

    For more general information on PGT in Thailand, see our PGT in Thailand guide and other guides. For common questions, visit our FAQ page.

    Frequently asked questions

    Can a mosaic embryo be retested in Thailand?

    Some Thai clinics may offer retesting of mosaic embryos through thawing and re-biopsy, but this is not standard practice. The embryo must survive the thaw, and the lab must have protocols for re-biopsy. Confirm directly with the clinic whether they offer this service and what the associated risks are.

    What is the success rate of transferring a mosaic embryo?

    Success rates for mosaic embryo transfer vary widely and depend on the level of mosaicism, the embryo's quality, and the patient's age. Some low-level mosaic embryos can result in healthy live births, but there is an increased risk of miscarriage or chromosomal abnormalities. Genetic counseling is essential before making a decision.

    Do Thai clinics accept mosaic embryos from overseas?

    Many Thai clinics accept embryos shipped from overseas, including mosaic embryos. However, they will need to review the embryo's genetic report and may have specific criteria for acceptance. Contact the clinic to discuss logistics, legal requirements, and shipping procedures.

    Is PGT-A mandatory for all IVF cycles in Thailand?

    No, PGT-A is optional and not required for all IVF cycles. It is typically recommended for patients of advanced maternal age, those with recurrent pregnancy loss, or those with a history of chromosomal abnormalities. Discuss with your doctor whether PGT-A is appropriate for your situation.

  • PGT result timing: laboratory stages and transfer planning

    How to use this guide

    This page provides the explanation. For a separate practical record, use Waiting for PGT results: a laboratory status tracker. Record the responsible provider’s answers rather than treating a generic example as confirmation for your case.

    Understanding PGT and Its Timeline

    The PGT result timetable depends on the ordered test, sample receipt, laboratory workflow and clinical review. Request the laboratory’s current estimate and the event from which that estimate is measured.

    Factors That Influence PGT Result Timing

    Type of PGT Test

    Different PGT tests require different processing times. PGT-A (aneuploidy screening) typically takes less time than PGT-M (monogenic disorders) or PGT-SR (structural rearrangements), which may involve more complex analysis. Confirm with your clinic which test you need and its estimated turnaround.

    Lab Schedule and Workflow

    Thai labs may have specific batch processing days. For example, biopsies may be collected on certain days of the week, and results may be released on fixed schedules. Ask your clinic about the lab’s weekly routine and how it aligns with your cycle.

    Number of Embryos Tested

    Testing multiple embryos can sometimes extend the timeline, though many labs process batches simultaneously. Your clinic can give you a more personalized estimate based on your expected number of embryos.

    Shipping and Logistics (if applicable)

    If your clinic sends biopsies to an external lab, additional shipping time may be needed. Confirm whether the lab is on-site or off-site, and factor in any courier delays.

    Impact on Fresh vs. Frozen Transfer Decision

    One of the most important planning decisions is whether to attempt a fresh embryo transfer or freeze all embryos for a later frozen embryo transfer (FET). PGT results directly influence this choice.

    Fresh Transfer

    Ask the treating team how sample collection, test completion and result interpretation affect the proposed transfer pathway. This page cannot confirm that results will be available for a particular transfer or that one pathway is mandatory.

    Frozen Transfer (FET)

    With a frozen transfer, embryos are biopsied and vitrified (frozen) while awaiting results. Once results are received, only euploid (normal) embryos are selected for transfer in a later cycle. This approach allows for PGT but requires additional time—typically one to two months between retrieval and transfer, depending on your clinic’s schedule and your personal timeline.

    Planning Your Cycle Timeline as an International Patient

    If you are traveling to Thailand for IVF with PGT, careful planning is essential. Here are key steps and questions to discuss with your clinic:

    • Initial consultation: Discuss your medical history, PGT options, and estimated timelines.
    • Cycle start: Plan your travel dates around your menstrual cycle and medication schedule.
    • Egg retrieval and biopsy: Coordinate your stay to cover the retrieval and any required follow-up.
    • Waiting period for results: You may return home while waiting for PGT results, but confirm how results will be communicated (email, portal, phone).
    • Frozen transfer preparation: If FET is needed, plan a second trip or discuss remote monitoring options with your clinic.

    Questions to Confirm with Your Clinic

    Because timelines can vary, always verify the following directly with your treating clinic:

    • What is the estimated turnaround time for my specific PGT test?
    • Does the lab process biopsies daily or on specific days?
    • What is the current expected report date, what could change it, and who will provide a status update?
    • How will I receive the results, and who will explain them?
    • What is the recommended interval between retrieval and FET?

  • How Are PGT Results Reported by Thai Labs? A Guide for Patients

    Introduction

    After undergoing preimplantation genetic testing (PGT) as part of your IVF cycle in Thailand, you will receive a laboratory report detailing the genetic status of each biopsied embryo. Understanding how these results are reported and what they mean is crucial for making informed decisions with your fertility team. This guide explains the typical format of PGT reports from Thai laboratories, how to interpret common terms like euploid, aneuploid, and mosaic, and what to consider when discussing your results with your doctor.

    Types of PGT and What They Test

    Thai laboratories offer three main types of PGT:

    • PGT-A (Aneuploidy): Screens embryos for the correct number of chromosomes (23 pairs). Aneuploidy (extra or missing chromosomes) is a common cause of implantation failure and miscarriage.
    • PGT-M (Monogenic): Tests for specific single-gene disorders (e.g., cystic fibrosis, thalassemia) when one or both parents carry a known mutation.
    • PGT-SR (Structural Rearrangement): Detects unbalanced chromosomal rearrangements (e.g., translocations, inversions) that can lead to abnormal embryos.

    Some labs offer combined testing (e.g., PGT-A + PGT-M) from a single biopsy.

    Typical Report Format

    While each laboratory may have its own template, most PGT reports from Thai clinics include the following sections:

    • Patient and Cycle Information: Your name, date of birth, cycle number, and date of biopsy.
    • Embryo Identification: Each biopsied embryo is assigned a unique ID or number, often linked to its developmental stage (e.g., day 5 or day 6 blastocyst).
    • Testing Method: The technology used (e.g., next-generation sequencing, NGS; or array comparative genomic hybridization, aCGH). NGS is now the most common method in Thailand.
    • Results per Embryo: A table or list showing each embryo’s genetic status. For PGT-A, this includes the chromosome copy number (e.g., 46,XX or 46,XY for normal) and any abnormalities detected. For PGT-M, the report indicates whether the embryo carries the mutation, is unaffected, or is a carrier (if applicable). For PGT-SR, it shows whether the embryo has a balanced or unbalanced rearrangement.
    • Interpretation: A summary classifying each embryo as euploid, aneuploid, or mosaic (for PGT-A). For PGT-M/SR, terms like “affected,” “unaffected,” or “carrier” may be used.
    • Quality Metrics: Some reports include DNA amplification success, contamination checks, and confidence scores.
    • Recommendations: The lab may suggest genetic counseling or further testing (e.g., confirmatory prenatal diagnosis if pregnancy occurs).

    Interpreting PGT-A Results: Euploid, Aneuploid, Mosaic

    PGT-A results fall into three main categories:

    • Euploid: The embryo has the expected number of chromosomes (46,XX or 46,XY). These embryos have the highest chance of implantation and developing into a healthy baby, but they are not guaranteed to result in a live birth.
    • Aneuploid: The embryo has extra or missing chromosomes (e.g., trisomy 21, monosomy X). These embryos are unlikely to implant or will likely miscarry; they are generally not recommended for transfer.
    • Mosaic: The embryo contains a mixture of euploid and aneuploid cells. Mosaicism is reported as a percentage (e.g., 20% mosaic). The clinical significance depends on the level and type of mosaicism. Some mosaic embryos may still result in a healthy baby, but the risk of abnormalities is higher. Discuss with your doctor whether a mosaic embryo is suitable for transfer.

    Note: PGT-A cannot detect all genetic conditions (e.g., microdeletions, uniparental disomy) and has a small error rate (typically <5%).

    Interpreting PGT-M and PGT-SR Results

    For PGT-M, the report will indicate whether the embryo inherited the mutation(s) tested. Results may be:

    • Unaffected: The embryo does not carry the mutation.
    • Carrier: The embryo carries one copy of a recessive mutation but is not expected to develop the disease.
    • Affected: The embryo carries the mutation(s) and is expected to develop the disorder.

    For PGT-SR, the report will state whether the embryo has a balanced (normal or carrier) or unbalanced (abnormal) chromosomal rearrangement. Balanced carriers are generally healthy but may have fertility issues later.

    Turnaround Time

    The time from embryo biopsy to receiving results varies by laboratory and testing complexity. For PGT-A, results are typically available within 1–2 weeks. PGT-M and PGT-SR may take longer (2–4 weeks) because they require custom probe development or family studies. Your clinic will provide an estimated timeline. Note that turnaround times can be affected by sample transport, lab workload, and the need for repeat testing.

    Discussing Results with Your Doctor

    Once you receive your PGT report, schedule a consultation with your fertility specialist and/or genetic counselor. Key points to discuss:

    • Which embryos are suitable for transfer: Euploid embryos are prioritized. For mosaic or carrier embryos, your doctor will explain the risks and success rates based on your specific situation.
    • Number of embryos available: PGT can reduce the number of transferable embryos, especially for older patients or those with genetic conditions. Discuss your options if few or no euploid embryos are available.
    • Limitations of testing: PGT is a screening tool, not a diagnostic test. It cannot guarantee a healthy baby or prevent all genetic disorders. Confirmatory prenatal testing (e.g., chorionic villus sampling or amniocentesis) is recommended if pregnancy occurs.
    • Next steps: Your doctor will advise on whether to proceed with a frozen embryo transfer (FET) in a subsequent cycle, or if additional testing (e.g., re-biopsy for inconclusive results) is needed.

    Alternatives and Limitations

    PGT is not suitable for everyone. Alternatives include:

    • No testing: Transferring embryos based on morphology alone.
    • Prenatal diagnosis: Testing during pregnancy (e.g., NIPT, amniocentesis).
    • Donor gametes: Using donor eggs or sperm to avoid genetic risks.

    Limitations of PGT include:

    • Not all embryos can be biopsied (e.g., poor-quality blastocysts).
    • Mosaicism can lead to false-positive or false-negative results.
    • PGT does not eliminate the risk of miscarriage or birth defects.

    Questions to Ask Your Clinic

    Before proceeding with PGT, consider asking your Thai clinic:

    • Which laboratory will perform the testing? Is it accredited (e.g., ISO 15189)?
    • What is the typical turnaround time for results?
    • How are mosaic results reported and managed?
    • What is the policy for inconclusive or failed results?
    • Are genetic counseling services available?

    Conclusion

    PGT results from Thai laboratories are reported in a detailed, standardized format that helps you and your doctor make informed decisions about embryo transfer. Understanding terms like euploid, aneuploid, and mosaic, as well as the limitations of testing, is essential. Always discuss your results with a qualified professional who can interpret them in the context of your medical history and treatment plan.

    Frequently asked questions

    What does a euploid embryo mean?

    A euploid embryo has the correct number of chromosomes (46,XX or 46,XY). It has the highest chance of implantation and developing into a healthy baby, but it is not a guarantee of pregnancy or live birth.

    Can a mosaic embryo be transferred?

    In some cases, mosaic embryos may be considered for transfer if no euploid embryos are available. The decision depends on the level and type of mosaicism, and should be made after thorough genetic counseling with your doctor.

    How long does it take to get PGT results in Thailand?

    Turnaround time varies by lab and test type. PGT-A results typically take 1–2 weeks, while PGT-M and PGT-SR may take 2–4 weeks. Your clinic will provide an estimated timeline.

    Is PGT 100% accurate?

    No, PGT has a small error rate (typically <5%) due to factors like mosaicism or technical limitations. Confirmatory prenatal testing is recommended if pregnancy occurs.

  • PGT embryo biopsy numbers: why counts vary across a cycle

    How to use this guide

    This page provides the explanation. For a separate practical record, use PGT embryo-count worksheet: track each laboratory stage. Record the responsible provider’s answers rather than treating a generic example as confirmation for your case.

    The number of embryos biopsied for preimplantation genetic testing (PGT) in Thailand varies significantly from one patient to another. There is no standard or guaranteed number because the process depends on multiple biological and clinical factors. This article explains the key factors that influence how many embryos reach the biopsy stage, what patients can typically expect, and important questions to ask your clinic.

    Key Factors That Determine the Number of Embryos Biopsied

    Number of Eggs Retrieved

    The starting point is the number of eggs collected during the egg retrieval procedure. This number depends on the patient’s age, ovarian reserve, and response to ovarian stimulation medications. A higher number of mature eggs generally leads to more embryos available for biopsy, but not all eggs will fertilize or develop normally.

    Fertilization Rate

    After egg retrieval, the eggs are fertilized with sperm (via IVF or ICSI). Ask the laboratory for the actual fertilisation report and its explanation; a general percentage does not predict this cycle. Only fertilized eggs (zygotes) will continue to develop into embryos.

    Embryo Development to Biopsy Stage

    For PGT, embryos are usually biopsied at the blastocyst stage, which occurs around day 5 or 6 after fertilization. Not all fertilized eggs will reach this stage. Ask which embryos reached the laboratory’s biopsy assessment stage and why others did not; do not substitute a generic conversion rate for the actual report. Embryos that arrest or stop developing before the blastocyst stage cannot be biopsied.

    Embryo Quality and Grading

    Embryologists grade embryos based on their morphology (appearance). Only embryos that meet certain quality criteria are considered suitable for biopsy. Poor-quality embryos may not be biopsied because they have a lower chance of leading to a successful pregnancy, and some clinics may have policies on which embryos are eligible for testing.

    Clinic Policies and Laboratory Practices

    Different clinics in Thailand may have varying policies regarding the minimum number of embryos required for PGT, the stage at which biopsy is performed, and whether they biopsy all available embryos or only those that meet specific criteria. Some clinics may recommend PGT only if there are a certain number of embryos, while others may proceed with fewer. It is essential to discuss your clinic’s specific approach.

    Typical Range of Embryos Biopsied

    While there is no fixed number, many patients who undergo PGT in Thailand may have between 2 and 8 embryos biopsied per cycle. However, some patients may have fewer (1 or none) if embryo development is poor, while others may have more if they produce a high number of eggs and embryos. The number is highly individual.

    What Happens After Biopsy?

    After biopsy, ask which laboratory received the sample, what stage the analysis has reached and when the issuing team expects to release and interpret the report. Do not turn an estimated turnaround into a confirmed transfer or travel date.

    Important Questions to Ask Your Clinic

    • What is your clinic’s average number of embryos biopsied per cycle for patients with my age and diagnosis?
    • At what stage do you perform the biopsy (day 5, day 6, or both)?
    • Do you biopsy all available blastocysts, or only those that meet certain quality criteria?
    • What is your lab’s success rate for embryo survival after biopsy?
    • How long does it take to receive PGT results?
    • What are the costs associated with biopsy and testing per embryo?

    Uncertainties and Limitations

    It is important to understand that the number of embryos biopsied cannot be predicted with certainty before the cycle begins. Even with a good number of eggs, embryo development can be unpredictable. Additionally, PGT itself has limitations, including the risk of inconclusive results, mosaicism, and the fact that it cannot guarantee a healthy baby. Discuss these aspects with your fertility specialist.

  • How PGT-M Works for Inherited Disorders in Thailand

    What Is PGT-M?

    Preimplantation Genetic Testing for Monogenic Disorders (PGT-M) is a technique used during in vitro fertilization (IVF) to identify embryos that carry a specific inherited genetic condition. It is designed for couples who know they are at risk of passing on a single-gene disorder, such as cystic fibrosis, Huntington’s disease, or thalassemia. PGT-M does not guarantee a healthy pregnancy or live birth, and it is not suitable for all patients. The process requires careful planning, specialized laboratory expertise, and a clear understanding of the limitations.

    Step 1: Genetic Counseling and Family History Review

    Before starting PGT-M, both partners undergo genetic counseling to confirm the diagnosis, identify the specific genetic mutation, and understand the inheritance pattern. The counselor will review family history and may recommend carrier testing for the partner if not already done. This step is essential to determine whether PGT-M is appropriate and to set realistic expectations. In Thailand, genetic counseling is offered at major IVF centers, often in collaboration with geneticists.

    Step 2: Probe Development – The Custom Test

    PGT-M requires a personalized genetic test, called a probe, that is designed to detect the specific mutation in the family. This is the most time-consuming part of the process. The laboratory needs DNA samples from the couple and, ideally, from an affected family member (such as a child or parent) to build a genetic map around the mutation. The probe uses markers (short tandem repeats or single nucleotide polymorphisms) that are linked to the disease gene. Developing the probe can take several weeks to months, depending on the complexity of the mutation and the laboratory’s workload.

    In Thailand, several IVF laboratories have the capability to design custom probes for PGT-M. These labs typically use next-generation sequencing (NGS) or polymerase chain reaction (PCR)-based methods. The probe development is performed in-house or in collaboration with international genetic testing facilities. Patients should confirm with their clinic whether probe development is done locally or sent abroad, as this affects timelines and costs.

    Step 3: IVF and Embryo Biopsy

    Once the probe is ready, the couple undergoes a standard IVF cycle to produce embryos. After fertilization, embryos are cultured in the laboratory for 5 to 6 days until they reach the blastocyst stage. At this point, a small number of cells (typically 5 to 10) are removed from the trophectoderm (the outer layer that will become the placenta) in a procedure called embryo biopsy. The biopsy is performed by an experienced embryologist using a laser to create a small opening in the embryo’s outer shell (zona pellucida) and gently aspirating the cells. The embryo is then frozen (vitrified) while the genetic analysis is performed.

    Thai IVF clinics generally follow international standards for embryo biopsy. The procedure is delicate and requires skilled embryologists to minimize damage to the embryo. The biopsied cells are sent to the genetics laboratory for analysis.

    Step 4: Genetic Analysis

    The biopsied cells are analyzed using the custom probe to determine whether each embryo carries the mutation. The analysis typically involves amplifying the DNA from the few cells and testing for the specific genetic markers. Results are usually available within 1 to 2 weeks. The laboratory will classify embryos as:

    • Unaffected (mutation-free): Embryos that do not carry the disease-causing mutation.
    • Affected: Embryos that carry the mutation.
    • Inconclusive: Embryos where the result is unclear due to technical issues or insufficient DNA.

    It is important to note that PGT-M only tests for the specific mutation requested. It does not screen for other genetic conditions or chromosomal abnormalities unless combined with PGT-A (aneuploidy testing). Some Thai labs offer combined PGT-A and PGT-M, but this should be discussed with the clinic.

    Step 5: Embryo Selection and Transfer

    Based on the genetic results, the couple and their doctor select one or more unaffected embryos for transfer. The frozen embryo is thawed and transferred into the uterus in a subsequent cycle. Any remaining unaffected embryos can be frozen for future use. Affected or inconclusive embryos are typically not transferred, though some couples may choose to transfer inconclusive embryos after further counseling.

    Embryo selection does not guarantee implantation, pregnancy, or a healthy child. Other factors such as maternal age, uterine health, and embryo quality also play a role.

    Laboratory Capabilities in Thailand

    Thailand has several IVF centers with genetics laboratories capable of performing PGT-M. These labs are often equipped with NGS platforms and PCR machines. However, the availability of custom probe development varies. Some clinics have in-house geneticists who design probes, while others outsource to specialized labs in Thailand or abroad. Patients should ask their clinic:

    • Does the lab develop probes in-house or use an external partner?
    • What is the estimated timeline for probe development and analysis?
    • Is the lab accredited by international bodies (e.g., ISO 15189)?
    • Can PGT-M be combined with PGT-A in a single biopsy?

    It is also worth noting that Thai regulations may affect the availability of PGT-M for certain conditions. Patients should confirm with their clinic whether the specific disorder is eligible for testing under current guidelines.

    Limitations and Considerations

    • Not all mutations can be tested: PGT-M works best for well-characterized single-gene disorders. For rare or complex mutations, probe development may not be possible.
    • Risk of misdiagnosis: Although rare, errors can occur due to contamination, allele dropout, or recombination. Confirmatory prenatal testing (e.g., amniocentesis) is recommended after pregnancy.
    • No guarantee of success: PGT-M does not improve the chance of IVF success. It only reduces the risk of passing on the specific genetic condition.
    • Emotional and financial cost: The process is time-consuming and expensive. Probe development alone can cost several thousand dollars, and the overall IVF-PGT cycle adds significant expense.

    Alternatives to PGT-M

    For some couples, alternatives may include:

    • Prenatal diagnosis: Chorionic villus sampling (CVS) or amniocentesis during pregnancy to test for the condition, with the option of termination if affected.
    • Donor gametes: Using donor eggs or sperm from a person who does not carry the mutation.
    • Preimplantation genetic testing for aneuploidy (PGT-A): If the concern is chromosomal abnormalities rather than a single-gene disorder.

    Each option has its own ethical, emotional, and medical considerations. Genetic counseling can help couples weigh the choices.

    Questions to Ask Your Clinic

    • What is the success rate for PGT-M at your clinic? (Note: success rates vary and should be interpreted cautiously.)
    • How many PGT-M cycles have you performed for my specific condition?
    • What is the timeline from probe development to embryo transfer?
    • What happens if the probe development fails or results are inconclusive?
    • Do you offer combined PGT-A and PGT-M?
    • What are the costs involved, and are there any guarantees?

    For more information, see our PGT in Thailand overview, patient guides, and frequently asked questions.

    Frequently asked questions

    How long does PGT-M take in Thailand?

    The entire process from probe development to embryo transfer can take several months. Probe development alone may take 4 to 8 weeks, followed by an IVF cycle (about 2 weeks), embryo biopsy, and genetic analysis (1 to 2 weeks). Timelines vary by clinic and the complexity of the mutation.

    Can PGT-M test for any genetic disorder?

    PGT-M is designed for single-gene disorders with a known mutation. It is not suitable for complex conditions caused by multiple genes or environmental factors. The feasibility depends on the specific mutation and the laboratory's ability to design a reliable probe.

    Is PGT-M legal in Thailand?

    PGT-M is available in Thailand for medical purposes, but regulations may restrict testing for non-medical traits (e.g., gender selection) or certain conditions. Patients should confirm with their clinic regarding legal and ethical guidelines.

    What is the success rate of PGT-M?

    Success rates depend on many factors, including maternal age, embryo quality, and laboratory accuracy. PGT-M does not increase the chance of pregnancy; it only reduces the risk of passing on the specific genetic condition. Clinics may report their own data, but no universal rate applies.

  • Thai vs US PGT Labs: Technology, Methods, and What to Consider

    Understanding PGT Technology Options

    Preimplantation genetic testing (PGT) helps identify genetic abnormalities in embryos created through IVF. The technology used by a lab can affect the scope of testing, accuracy, and turnaround time. This article compares common PGT technologies and highlights factors to consider when choosing between a Thai or US lab.

    Common PGT Technologies

    Next-Generation Sequencing (NGS)

    NGS is a method used for PGT-A (aneuploidy screening) and can also be applied to PGT-M (monogenic disorders) and PGT-SR (structural rearrangements). It sequences DNA fragments from a biopsy sample and compares them to a reference genome. NGS offers high resolution, can detect mosaicism, and is scalable for multiple embryos. Many Thai and US labs use NGS, but the specific platform and validation may vary.

    Array Comparative Genomic Hybridization (aCGH)

    aCGH is a method that compares patient DNA to a reference sample using fluorescent labels. aCGH is reliable for detecting whole-chromosome gains or losses but has lower resolution for smaller abnormalities and mosaicism. Some labs still use aCGH, especially for PGT-A.

    Single Nucleotide Polymorphism (SNP) Array

    SNP arrays analyze thousands of genetic markers across the genome. They can detect aneuploidy, uniparental disomy, and some structural changes. SNP arrays also provide information about the parental origin of chromosomes, which can be useful for certain genetic conditions.

    Turnaround Times

    Turnaround time for PGT results depends on the technology, lab workflow, and whether the test is performed locally or sent to a reference lab. Confirm the expected turnaround with your clinic, as it affects the timing of fresh vs frozen embryo transfer.

    Regulatory Differences

    In the United States, PGT is regulated under the Clinical Laboratory Improvement Amendments (CLIA) and by the Food and Drug Administration (FDA) for certain test components. Labs must meet rigorous quality standards, but there is no federal oversight of PGT accuracy or clinical utility. Some states have additional regulations.

    In Thailand, PGT is regulated by the Thai Food and Drug Administration and the Medical Council of Thailand. Labs may hold international accreditations such as JCI, ISO, or RTAC. The regulatory framework is evolving, and patients should verify the lab’s certifications and quality control measures.

    Comparing Thai and US Labs: Key Considerations

    Technology Availability

    Both countries offer NGS, aCGH, and SNP array. However, the specific platform and validation may differ. Ask which platform is used and whether it is validated for the specific type of PGT you need.

    Cost

    PGT costs vary widely. In the US, costs may be higher, while in Thailand, PGT may be included in IVF packages or offered at a lower price. However, lower cost does not necessarily mean lower quality. Compare what is included: biopsy, genetic counseling, and reporting.

    Experience and Accreditation

    Look for labs with experience in the specific PGT method you need. Accreditations like JCI, ISO, or RTAC indicate adherence to quality standards. Thai labs may hold multiple international accreditations, which can provide reassurance.

    Shipping and Logistics

    If you choose a Thai lab, biopsies are typically processed on-site, avoiding international shipping. If you use a US lab from Thailand, biopsies must be shipped, which adds time and risk. Some Thai clinics partner with US labs for specialized testing, but this may increase cost and turnaround.

    Frequently asked questions

    What is the main difference between NGS and aCGH for PGT?

    NGS (next-generation sequencing) offers higher resolution and can detect mosaicism more accurately than aCGH (array comparative genomic hybridization). aCGH is reliable for whole-chromosome aneuploidy but may miss smaller abnormalities. NGS is now the preferred method for PGT-A in most labs.

    Are Thai PGT labs as advanced as US labs?

    Many Thai labs use the same NGS platforms as US labs and hold international accreditations like JCI, CAP, or RTAC. However, regulatory oversight differs. Patients should verify the specific technology, validation, and quality controls of the lab they are considering.

    How long does PGT take in Thailand vs the US?

    Turnaround time is similar, typically 7–14 days. Thai labs often process biopsies on-site, avoiding shipping delays. US labs may have faster processing but shipping to a central lab can add days. Confirm with your clinic.

    Is PGT cheaper in Thailand than in the US?

    Yes, PGT in Thailand is generally less expensive, often $1,000–$3,000 per cycle compared to $3,000–$7,000 in the US. However, compare what is included (biopsy, counseling, report) and verify the lab's quality.

    Can Thai labs perform PGT-M for single gene disorders?

    Yes, some Thai labs offer PGT-M. Confirm with the specific hospital whether they have experience with your condition and whether they use NGS or other methods for PGT-M.
