  • No-Result PGT Report: Questions to Discuss with Your Clinic

    Receiving a PGT report with no result can be disappointing and confusing. You may wonder what went wrong, whether the embryo is still usable, and what your options are. This guide explains what a no-result outcome may mean and provides a practical list of questions to discuss with your clinic. It is not medical advice, but a framework to help you have a more informed conversation with your care team.

    At a glance

    • A no-result PGT report means the laboratory could not provide a definitive genetic result for that embryo.
    • Possible reasons include technical issues, insufficient DNA, or biological factors.
    • Your clinic can explain the specific reason and discuss whether re-biopsy, transfer without testing, or other options are appropriate.
    • Ask about the laboratory’s protocols, success rates for re-biopsy, and any additional costs or timelines.

    What does a no-result PGT report mean?

    PGT (preimplantation genetic testing) is performed on embryos created through IVF. The test analyzes a small number of cells taken from the embryo to look for specific genetic conditions. A no-result report means that the laboratory could not obtain a clear genetic result for that embryo. This is not the same as a normal or abnormal result; it is an inconclusive outcome.

    There are several possible reasons for a no-result report. These may include:

    • Insufficient DNA in the sample
    • Technical issues during the testing process
    • DNA degradation or contamination
    • Biological factors related to the embryo itself

    Your clinic and the genetic laboratory can provide more specific information about your case. It is important to remember that a no-result report does not necessarily mean the embryo is abnormal or unusable. It simply means the test did not produce a definitive answer.

    Questions to ask about the no-result report

    When you receive a no-result PGT report, schedule a discussion with your clinic. Here are key questions to ask:

    About the reason for the no-result

    • What was the specific reason for the no-result in our case?
    • Was the issue related to the embryo, the biopsy, or the laboratory process?
    • How common is a no-result outcome in your laboratory?

    About the embryo and next steps

    • Is the embryo still viable for transfer?
    • What are our options: re-biopsy, transfer without testing, or discard?
    • If we consider re-biopsy, what is the success rate for obtaining a result?
    • Are there any risks to the embryo from a second biopsy?

    About the laboratory and testing process

    • Which laboratory performed the test, and what are their quality controls?
    • What is the laboratory’s track record for successful PGT results?
    • Are there alternative testing methods that might be more suitable?

    About costs and logistics

    • Will there be additional costs for re-biopsy or repeat testing?
    • How long will we need to wait for a new result?
    • Are there any implications for our IVF cycle timeline?

    About counselling and support

    • Can we speak with a genetic counsellor to understand the implications?
    • What emotional support resources are available?

    Understanding re-biopsy

    Re-biopsy involves taking another sample from the same embryo for a second attempt at PGT. This is not always possible or recommended. The decision depends on the embryo’s quality, the reason for the no-result, and the clinic’s protocols. Your clinic can explain whether re-biopsy is an option in your case and what the chances of obtaining a result might be.

    It is important to note that re-biopsy may carry some risks, such as damage to the embryo. Your clinic should discuss these risks with you in detail.

    Transfer without testing

    In some cases, you may choose to transfer an embryo without a PGT result. This is a personal decision that should be made with the guidance of your medical team. They can help you understand the potential implications for prenatal testing and the health of the child. It is essential to have a thorough discussion about the benefits and risks before making this choice.

    Questions to ask about transfer without testing

    • What are the potential risks and benefits of transferring an untested embryo?
    • What prenatal testing options would be available if we proceed with transfer?
    • How does this decision affect our chances of pregnancy and live birth?

    Emotional and psychological considerations

    A no-result PGT report can be emotionally challenging. You may feel anxious, disappointed, or uncertain about the future. It is normal to have these feelings. Consider seeking support from a counsellor or a support group for individuals going through fertility treatment. Your clinic may also have resources to help you cope.

    Next steps: a checklist for your discussion

    1. Write down all your questions before the appointment.
    2. Bring a partner or trusted friend for support.
    3. Ask for a clear explanation of the no-result reason.
    4. Discuss all possible options, including re-biopsy and transfer without testing.
    5. Ask about costs, timelines, and any additional procedures.
    6. Request written information about the laboratory and its quality standards.
    7. Consider a second opinion if you feel uncertain.

    Conclusion

    A no-result PGT report is not the end of the road. It is a signal to have a detailed conversation with your clinic about your options. By asking the right questions, you can make an informed decision that aligns with your values and medical situation. Remember, your clinic is there to support you through this process.

    Frequently asked questions

  • PGT-M Preparation Checklist for a Known Single-Gene Condition

    If you are considering PGT-M (preimplantation genetic testing for monogenic disorders) for a known single-gene condition, preparation involves more than just booking an appointment. You will need to gather medical records, understand how the testing works, and ask the right questions to determine if PGT-M is feasible for your situation. This checklist will guide you through the key steps, but remember that every case is unique—your clinic will provide specific instructions based on your genetic results and treatment plan.

    At a Glance

    • Collect genetic reports and family history details.
    • Confirm the genetic diagnosis and the specific gene/mutation.
    • Ask about the need for a probe or test development.
    • Understand the IVF cycle and biopsy process.
    • Discuss timelines, costs, and legal considerations with your clinic.

    Step 1: Gather Your Genetic Records

    Your clinic will need detailed information about the genetic condition. Start by collecting:

    • The genetic test report that identified the condition in you or your partner.
    • Any carrier screening results.
    • Family history details, including affected and unaffected relatives.
    • If available, genetic test results from affected family members.

    These records help the lab understand the specific mutation and design the PGT-M test. If you have not had genetic testing, your clinic can refer you to a genetic counselor or specialist.

    Step 2: Confirm the Genetic Diagnosis

    Before proceeding, ensure that the genetic condition is clearly identified. You should know:

    • The exact gene involved.
    • The specific mutation or variant.
    • The inheritance pattern (autosomal dominant, recessive, X-linked, etc.).

    If this information is unclear, ask your genetic counselor or doctor to explain it. PGT-M requires a precise genetic target to test embryos accurately.

    Step 3: Understand Lab Feasibility

    Not all genetic conditions are equally amenable to PGT-M. The lab will need to develop a customized test, which may require:

    • Blood samples from you and your partner.
    • Sometimes samples from other family members (e.g., an affected child or parent).
    • Time to design and validate the test before your IVF cycle begins.

    Ask your clinic about their laboratory’s experience with your specific condition. They can tell you if a test is feasible and how long it will take to prepare.

    Step 4: Plan Your IVF Cycle

    PGT-M is performed in conjunction with IVF. You will need to undergo ovarian stimulation, egg retrieval, and fertilization. After embryos develop, a few cells are biopsied and sent for genetic testing. Consider:

    • Your overall health and fertility status.
    • Any previous IVF experience.
    • The number of embryos you hope to test.

    Your clinic will provide a personalized treatment plan, including medication protocols and timing.

    Step 5: Ask Key Questions

    Prepare a list of questions for your clinic. Here are some to consider:

    • How long will it take to develop the PGT-M test for our specific mutation?
    • What samples are needed from us and our family members?
    • What is the success rate for embryo biopsy and testing at your lab?
    • How many embryos typically reach the biopsy stage?
    • What are the costs for PGT-M testing, and what does that include?
    • Are there any legal or ethical considerations we should be aware of?
    • How will results be communicated, and what support is available?

    Step 6: Consider Logistics and Support

    If you are traveling for treatment, plan for:

    • Time off work and travel arrangements.
    • Accommodation near the clinic.
    • Translation services if needed.
    • Emotional support, such as counseling or support groups.

    PGT-M can be emotionally challenging. It is important to have a support system in place.

    Next Steps

    After you have gathered your records and asked your questions, you can decide whether to proceed. Your clinic will guide you through the next steps, which may include:

    • Genetic counseling sessions.
    • Blood tests and sample collection.
    • IVF cycle scheduling.
    • Embryo transfer planning.

    Remember, PGT-M is a complex process, but with careful preparation, you can make informed decisions.

    Frequently asked questions

    What is PGT-M?

    PGT-M is a genetic test performed on embryos created through IVF to identify whether they carry a specific single-gene disorder. It helps families at risk of passing on a known genetic condition to select embryos that are unaffected.

    How long does PGT-M testing take?

    The timeline varies. Developing a customized test for your specific mutation can take several weeks to months. After embryo biopsy, results are typically available within a few days to a couple of weeks. Your clinic will provide a specific timeline.

    Do we need to provide samples from family members?

    Often, yes. The lab may need samples from you and your partner, and sometimes from an affected child or other relatives, to design an accurate test. Your clinic will advise on exactly what is needed.

    Is PGT-M legal in Thailand?

    The legal status of PGT-M can vary and may be subject to regulations. It is essential to confirm with your clinic and relevant authorities about the current legal framework and any restrictions that may apply.

    What are the risks of PGT-M?

    PGT-M involves embryo biopsy, which carries a small risk of damage to the embryo. There is also a small chance of misdiagnosis. Your clinic will explain the risks and limitations in detail.

  • How to Interpret PGT-A Results: A Patient’s Guide

    If you are waiting for PGT-A results, you likely have questions about what the findings will mean for your IVF journey. This guide explains the types of results you may receive, how to interpret them, and what they might mean for your next steps. Remember, PGT-A is a screening tool, not a guarantee of pregnancy or a healthy baby. Your clinic will provide personalized advice based on your results and medical history.

    At a Glance: Key Points About PGT-A Results

    • PGT-A screens embryos for chromosomal abnormalities before transfer.
    • Results are typically reported as euploid, aneuploid, or mosaic.
    • Euploid embryos have the expected number of chromosomes and are usually prioritized for transfer.
    • Aneuploid embryos have missing or extra chromosomes and are generally not transferred.
    • Mosaic embryos have a mix of normal and abnormal cells; their transfer may be considered in certain situations.
    • PGT-A does not guarantee a successful pregnancy or a healthy baby.

    What Is PGT-A?

    Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a test performed on embryos created through IVF. It checks for the correct number of chromosomes. Humans typically have 46 chromosomes in each cell. Having too many or too few chromosomes can lead to implantation failure, miscarriage, or genetic conditions such as Down syndrome.

    PGT-A is optional and not necessary for everyone. Your doctor may recommend it based on your age, medical history, or previous IVF outcomes. It is important to discuss the benefits, limitations, and costs with your clinic.

    Understanding Your PGT-A Results

    PGT-A results are usually reported as one of the following:

    Euploid

    A euploid embryo has the expected number of chromosomes (46). This is considered a normal result. Euploid embryos have the highest chance of implanting and developing into a healthy baby, but they do not guarantee a successful pregnancy. Other factors, such as embryo quality and uterine environment, also matter.

    Aneuploid

    An aneuploid embryo has missing or extra chromosomes. For example, trisomy 21 (three copies of chromosome 21) causes Down syndrome. Aneuploid embryos are generally not transferred because they are unlikely to result in a live birth and may cause miscarriage. Your clinic will discuss options, which may include discarding the embryo or, in some cases, using it for research (with your consent).

    Mosaic

    A mosaic embryo has a mixture of cells with normal chromosomes and cells with abnormal chromosomes. The percentage of abnormal cells is usually reported. Mosaic embryos may have a lower chance of implantation than euploid embryos, but some can still lead to a healthy baby. The decision to transfer a mosaic embryo is complex and depends on the specific chromosomes involved, the percentage of abnormal cells, and your personal circumstances. Your clinic may recommend genetic counseling to help you decide.

    What Do PGT-A Results Mean for Transfer Decisions?

    Your doctor will use your PGT-A results, along with other factors, to recommend which embryo(s) to transfer. Typically, euploid embryos are prioritized. If you have no euploid embryos, your doctor may discuss the option of transferring a mosaic embryo, but this is not always recommended. Aneuploid embryos are usually not transferred.

    It is important to understand that PGT-A does not test for all genetic conditions. It only screens for chromosomal abnormalities. Other genetic tests, such as PGT-M, are used for specific inherited diseases.

    Questions to Ask Your Clinic

    • What type of PGT test was performed on my embryos?
    • How are my results reported? What is the exact terminology?
    • What is the percentage of abnormal cells in a mosaic embryo, and which chromosomes are affected?
    • What are the success rates for transferring euploid versus mosaic embryos in my age group?
    • Are there any additional tests I should consider?
    • What are the costs associated with PGT and any follow-up testing?

    Next Steps After Receiving Your Results

    1. Schedule a consultation with your doctor to review your results in detail.
    2. Ask for a written copy of your results and any relevant reports.
    3. Discuss the implications for your transfer plan, including timing and number of embryos to transfer.
    4. If you have mosaic embryos, ask about genetic counseling to understand the risks and options.
    5. Consider your emotional well-being; waiting for results can be stressful. Seek support from your clinic or a counselor if needed.

    Limitations of PGT-A

    PGT-A is a powerful tool, but it has limitations. It cannot guarantee a successful pregnancy or a healthy baby. Embryos can be damaged during the biopsy process, although this is rare. Also, PGT-A may not detect all chromosomal abnormalities, and some embryos may be misclassified. The accuracy of the test depends on the laboratory and the technology used.

    Furthermore, PGT-A does not test for single-gene disorders (like cystic fibrosis) or structural rearrangements (like translocations). Those require PGT-M or PGT-SR, respectively. Your clinic can explain which tests are appropriate for your situation.

    Frequently Asked Questions

    What is the difference between PGT-A and PGT-M?

    PGT-A screens for chromosomal abnormalities (aneuploidy), while PGT-M tests for specific single-gene disorders that are inherited. PGT-M is used when one or both parents carry a known genetic mutation.

    Can a mosaic embryo result in a healthy baby?

    Yes, some mosaic embryos can lead to a healthy baby, but the chance is generally lower than with a euploid embryo. The outcome depends on the specific chromosomes involved and the percentage of abnormal cells. Your clinic can provide more personalized information.

    What if all my embryos are aneuploid?

    If all embryos are aneuploid, they are typically not transferred. Your doctor will discuss options, which may include a new IVF cycle, using donor eggs or sperm, or considering other family-building options. Genetic counseling can help you explore these choices.

    Is PGT-A mandatory for IVF?

    No, PGT-A is optional. It is not necessary for all patients. Your doctor may recommend it based on your age, medical history, or previous IVF outcomes. Discuss the pros and cons with your clinic to make an informed decision.

    How long does it take to get PGT-A results?

    The time to receive results varies by laboratory and the testing method used. Your clinic will provide an estimated timeline. Typically, results may take several days to a few weeks.

  • How PGT-M Works for Single Gene Disorders in Thailand

    Understanding PGT-M

    Preimplantation genetic testing for monogenic disorders (PGT-M) is a technique used during in vitro fertilization (IVF) to identify embryos that do not carry a specific single-gene disorder. It is designed for couples or individuals who have a known genetic condition in their family and wish to reduce the risk of passing it on to their children.

    PGT-M is not a guarantee of a healthy baby, nor is it suitable for everyone. It is a complex process that requires careful planning, genetic counseling, and laboratory expertise. This article explains how PGT-M works, what you can expect, and what to prepare if you are considering it in Thailand.

    At a Glance: Key Points About PGT-M

    • PGT-M is used for single-gene disorders such as cystic fibrosis, sickle cell anemia, or Huntington’s disease.
    • It requires IVF because embryos are created in the laboratory and tested before transfer.
    • The process involves genetic testing of embryos to identify those without the specific mutation.
    • Success depends on many factors, including the number of viable embryos and the accuracy of the genetic test.
    • International patients need to plan for medical records, legal considerations, and travel logistics.

    Who Might Consider PGT-M?

    PGT-M may be considered by:

    • Couples where one or both partners carry a known single-gene mutation.
    • Individuals with a family history of a genetic disorder who want to avoid passing it on.
    • Couples who have had a child with a genetic condition and want to reduce the risk in future pregnancies.

    Before proceeding, you should have a confirmed genetic diagnosis and understand the inheritance pattern of the condition. Genetic counseling is essential to discuss the implications and alternatives.

    The PGT-M Process: Step by Step

    1. Genetic Consultation and Testing

    The first step is a genetic consultation with a specialist. You will need to provide detailed medical and family history. The clinic will likely require genetic test results from you and your partner to identify the specific mutation. This may involve blood or saliva samples.

    2. IVF Cycle

    PGT-M is performed in conjunction with IVF. You will undergo ovarian stimulation to produce multiple eggs, which are then retrieved and fertilized with sperm in the laboratory. The resulting embryos are cultured for several days.

    3. Embryo Biopsy

    On day 5 or 6 of development, a few cells are removed from each embryo (trophectoderm biopsy). This is done carefully to minimize damage to the embryo. The biopsy is sent to a genetic laboratory for analysis.

    4. Genetic Testing

    The biopsied cells are tested for the specific single-gene disorder. The laboratory uses techniques such as polymerase chain reaction (PCR) or next-generation sequencing to detect the mutation. The results typically take a few days to a few weeks.

    5. Embryo Transfer

    Only embryos that are unaffected (not carrying the mutation) are considered for transfer. A healthy embryo is selected and transferred to the uterus. Any remaining unaffected embryos may be frozen for future use.

    What to Prepare as an International Patient

    If you are traveling to Thailand for PGT-M, preparation is key. Here are the main areas to consider:

    Medical Records

    You will need to provide comprehensive medical records, including:

    • Genetic test results confirming the diagnosis.
    • Details of any previous pregnancies or children affected by the condition.
    • Medical history of both partners.
    • Any prior IVF or fertility treatment records.

    Make sure these documents are translated into English if they are in another language.

    Legal and Ethical Considerations

    PGT-M is regulated differently in each country. In Thailand, you should confirm the legal status of PGT-M and any requirements for international patients. This may include consent forms and approval from a medical ethics committee.

    Travel and Accommodation

    Plan for a stay of several weeks, as the IVF cycle and testing take time. Consider accommodation near the clinic, transportation, and support for recovery after egg retrieval.

    Costs

    The cost of PGT-M in Thailand varies depending on the clinic, the complexity of the genetic test, and the number of embryos tested. Ask for a detailed breakdown of fees, including IVF, biopsy, genetic testing, and any additional procedures.

    Questions to Ask Your Clinic

    Before choosing a clinic, ask these questions:

    • What is your experience with PGT-M for my specific genetic condition?
    • How many embryos are typically biopsied and tested per cycle?
    • What is the turnaround time for genetic results?
    • How do you handle inconclusive or ambiguous results?
    • What are the success rates for PGT-M in your clinic? (Ask for specific data, not general claims.)
    • What support do you offer for international patients, such as translation services or coordination?

    Alternatives and Limitations

    PGT-M is not the only option. Alternatives include:

    • Prenatal diagnosis (e.g., chorionic villus sampling or amniocentesis) during pregnancy.
    • Using donor eggs or sperm to avoid passing on the genetic condition.
    • Adoption or remaining childless.

    PGT-M has limitations. It does not eliminate the risk of all genetic disorders, only the specific one tested. There is also a small chance of misdiagnosis or no embryos being unaffected. The process can be emotionally and physically demanding.

    Next Steps

    If you are considering PGT-M in Thailand, start by:

    1. Consulting with a genetic counselor in your home country to confirm your diagnosis and discuss options.
    2. Researching fertility clinics in Thailand that offer PGT-M.
    3. Contacting clinics to ask about their experience, success rates, and support for international patients.
    4. Preparing your medical records and planning your travel.

    Frequently asked questions

    What is the difference between PGT-M and PGT-A?

    PGT-M tests for a specific single-gene disorder, while PGT-A screens for chromosomal abnormalities (aneuploidy). They are used for different purposes and can be performed together in some cases.

    How long does the PGT-M process take?

    The entire process, from genetic consultation to embryo transfer, typically takes several weeks to a few months. The genetic testing itself may take a few days to a few weeks, depending on the laboratory.

    Is PGT-M legal in Thailand?

    PGT-M is available in Thailand, but regulations may vary. It is important to confirm the legal status and any requirements with the clinic and relevant authorities before proceeding.

    What are the risks of embryo biopsy?

    Embryo biopsy is generally considered safe, but there is a small risk of damage to the embryo. The procedure is performed by experienced embryologists to minimize this risk.

    Can PGT-M guarantee a healthy baby?

    No, PGT-M reduces the risk of passing on a specific genetic disorder, but it does not guarantee a healthy baby. There are other factors that can affect pregnancy and child health.

  • Understanding PGT-P: Polygenic Risk Testing in IVF

    PGT-P (preimplantation genetic testing for polygenic disorders) is a newer type of genetic screening that estimates the likelihood of an embryo developing certain common conditions influenced by multiple genes, such as type 2 diabetes, heart disease, or autoimmune disorders. Unlike PGT-A (aneuploidy screening) or PGT-M (single-gene disorder testing), PGT-P does not look for a specific mutation but rather calculates a polygenic risk score based on many genetic variants.

    In Thailand, PGT-P is available at some fertility centers, but it is not universally recommended. It is considered an emerging technology with ongoing debate about its clinical utility. This guide explains what PGT-P is, how it differs from other PGT tests, when it might be considered, and important limitations to discuss with your doctor.

    At a Glance: Key Points About PGT-P

    • PGT-P estimates risk for common polygenic conditions, not single-gene disorders.
    • It is an optional, emerging test—not a standard part of IVF.
    • Results are probabilistic, not diagnostic.
    • Availability and policies vary by clinic in Thailand.
    • Discuss with a genetic counselor to understand benefits and limitations.

    What Is PGT-P?

    PGT-P stands for preimplantation genetic testing for polygenic disorders. It is a technique that analyzes embryos created through IVF to estimate their genetic risk for conditions that are influenced by many genes and environmental factors. These conditions include type 2 diabetes, coronary artery disease, certain cancers, and autoimmune diseases.

    The test calculates a polygenic risk score (PRS) by looking at thousands of small genetic variations across the genome. Each variation contributes a small amount to the overall risk. The score is compared to a reference population to estimate whether an embryo has a higher or lower relative risk for a particular condition.

    It is important to understand that PGT-P does not diagnose a disease. It only provides a statistical estimate of risk. A high-risk score does not mean the child will definitely develop the condition, and a low-risk score does not guarantee protection.

    How PGT-P Differs from PGT-A and PGT-M

    To understand PGT-P, it helps to know the other common types of PGT:

    • PGT-A (aneuploidy screening): Checks for the correct number of chromosomes. It identifies embryos with extra or missing chromosomes, which often cause implantation failure or miscarriage.
    • PGT-M (monogenic disorders): Tests for a specific single-gene mutation, such as cystic fibrosis or Huntington’s disease, when one or both parents carry the mutation.
    • PGT-SR (structural rearrangements): Detects chromosomal structural changes like translocations or inversions.

    PGT-P is different because it does not look for a specific mutation or chromosomal abnormality. Instead, it assesses the combined effect of many genetic variants to estimate risk for common, complex diseases.

    When Is PGT-P Recommended?

    PGT-P is not a routine test. It may be considered in specific situations, such as:

    • When a couple has a strong family history of a polygenic condition, such as early-onset heart disease or type 2 diabetes.
    • When patients are already undergoing IVF with PGT-A and want additional risk information.
    • When patients are interested in reducing the likelihood of passing on polygenic risk to their children.

    However, professional guidelines vary. Many reproductive medicine societies do not yet endorse PGT-P for routine use due to limited evidence and ethical concerns. It is essential to discuss with your fertility specialist and a genetic counselor whether PGT-P is appropriate for your situation.

    How PGT-P Is Performed

    The process is similar to other PGT tests:

    1. IVF cycle: Eggs are retrieved and fertilized to create embryos.
    2. Embryo biopsy: A few cells are removed from the embryo, usually on day 5 or 6 (blastocyst stage).
    3. Genetic analysis: The cells are analyzed to generate a polygenic risk score.
    4. Embryo selection: Based on the scores, you and your doctor decide which embryos to transfer.

    It is important to note that PGT-P requires a biopsy, which is an invasive procedure. While the risk is low, there is a small chance of embryo damage. Also, not all embryos may be suitable for biopsy.

    Potential Benefits and Limitations

    Potential Benefits

    • Provides additional information about the risk of common conditions.
    • May help reduce the risk of passing on polygenic diseases.
    • Can be combined with PGT-A to give a more comprehensive genetic picture.

    Limitations and Considerations

    • Not diagnostic: A risk score is not a diagnosis. Many factors, including environment and lifestyle, influence disease development.
    • Limited predictive power: For many conditions, the genetic contribution is small, so the score may not significantly change clinical management.
    • Ethical concerns: There is debate about selecting embryos based on polygenic risk, as it may lead to discrimination or unrealistic expectations.
    • Cost and availability: PGT-P is expensive and may not be covered by insurance. Not all clinics in Thailand offer it.
    • Uncertain long-term outcomes: The technology is relatively new, and long-term health outcomes are not yet fully known.

    PGT-P in Thailand: Availability and Considerations

    In Thailand, PGT-P is offered at some advanced fertility centers, but it is not as widely available as PGT-A or PGT-M. The availability may depend on the clinic’s laboratory capabilities and the expertise of its genetic team.

    If you are considering PGT-P in Thailand, here are some questions to ask your clinic:

    • Do you offer PGT-P? If so, which conditions are included in the panel?
    • What is the cost of PGT-P, and is it separate from other PGT tests?
    • How many embryos are typically needed for a successful PGT-P cycle?
    • What is the accuracy and validation of the risk scores?
    • Do you have a genetic counselor who can explain the results?

    It is also important to consider that PGT-P is not a substitute for prenatal screening or postnatal care. Even with a low-risk score, a child may still develop a condition, and a high-risk score does not mean the condition will occur.

    Alternatives to PGT-P

    If you are concerned about polygenic conditions, there are other options to consider:

    • Preconception carrier screening: Tests parents for single-gene mutations that could be passed on.
    • Prenatal testing: During pregnancy, tests like NIPT or amniocentesis can screen for certain conditions.
    • Lifestyle and medical management: For many polygenic conditions, early detection and lifestyle changes can reduce risk.

    Discuss these options with your healthcare provider to make an informed decision.

    Questions to Ask Your Clinic

    Before deciding on PGT-P, consider asking your fertility team:

    • What is the scientific evidence supporting PGT-P for my specific situation?
    • How will the results be used in embryo selection?
    • What are the risks of embryo biopsy?
    • Are there any ethical or legal considerations in Thailand?
    • What is the success rate of IVF with PGT-P in your clinic?

    Next Steps

    If you are exploring PGT-P, here is a simple checklist:

    1. Research and understand the basics of PGT-P.
    2. Consult with a fertility specialist to discuss your medical history.
    3. Ask if PGT-P is available and whether it is recommended for you.
    4. Meet with a genetic counselor to review potential risks and benefits.
    5. Consider the costs and whether you have the resources to proceed.

    Remember, PGT-P is an evolving technology. Stay informed and make decisions based on the best available evidence and professional guidance.

    Frequently asked questions

    What is the difference between PGT-P and PGT-A?

    PGT-A checks for chromosomal abnormalities (aneuploidy), while PGT-P estimates the risk of polygenic conditions based on multiple genetic variants. PGT-A is more established and widely used, whereas PGT-P is newer and less commonly recommended.

    Is PGT-P available in Thailand?

    Yes, some fertility centers in Thailand offer PGT-P, but it is not universally available. You should check with individual clinics to see if they provide this testing and what conditions are included.

    Is PGT-P recommended for everyone undergoing IVF?

    No, PGT-P is not recommended for everyone. It is typically considered only in specific cases, such as a strong family history of polygenic conditions. Most professional guidelines do not endorse routine use due to limited evidence.

    What are the limitations of PGT-P?

    PGT-P provides only a statistical risk estimate, not a diagnosis. It has limited predictive power for many conditions, and there are ethical concerns about selecting embryos based on polygenic risk. The technology is also relatively new, so long-term outcomes are uncertain.

    How much does PGT-P cost in Thailand?

    The cost of PGT-P varies by clinic and is not typically covered by insurance. It is generally more expensive than PGT-A or PGT-M. You should contact clinics directly for current pricing.

  • How Much Does PGT-A Testing Cost in Thailand? A Guide to Understanding the Price

    If you are exploring IVF with preimplantation genetic testing for aneuploidy (PGT-A) in Thailand, one of the first questions you likely have is: “How much does it cost?” The honest answer is that there is no single fixed price. PGT-A costs in Thailand can vary significantly depending on several factors, including the number of embryos tested, the laboratory fees, and the specific package your clinic offers. This guide breaks down the cost components and provides practical questions to ask when comparing quotes.

    At a Glance: Key Cost Factors

    • Number of embryos tested: Most clinics charge per embryo, so the total cost rises with more embryos.
    • Laboratory fees: PGT-A requires specialized lab equipment and expertise, which is reflected in the price.
    • Clinic packages: Some clinics bundle PGT-A with IVF cycles, which may offer savings compared to separate fees.
    • Additional services: Genetic counseling, biopsy procedures, and shipping (if samples are sent abroad) may add to the total.

    Understanding the Cost Components

    PGT-A is a multi-step process that involves embryo biopsy, genetic analysis, and often genetic counseling. Each step has associated costs that contribute to the final price.

    Embryo Biopsy

    Before testing, a few cells are removed from each embryo. This procedure requires skilled embryologists and specialized equipment. The biopsy fee is typically charged per embryo or as part of a package.

    Genetic Analysis

    The biopsied cells are sent to a genetics laboratory to analyze the chromosomes. This analysis can be done in-house or at an external lab. The cost depends on the technology used (e.g., next-generation sequencing) and the number of embryos tested.

    Genetic Counseling

    Many clinics include a session with a genetic counselor to help you understand the results and their implications. This may be included in the package or billed separately.

    Why Prices Vary Between Clinics

    Thailand has many fertility clinics, each with its own pricing structure. Some factors that influence price differences include:

    • Location: Clinics in Bangkok may have higher overhead costs than those in other cities.
    • Laboratory accreditation: Labs with international accreditation may charge more for their services.
    • Technology: Clinics using the latest genetic testing platforms may have higher fees.
    • Included services: Some packages include medications, monitoring, or additional tests, which can affect the overall price.

    What to Ask When Comparing Quotes

    When you receive quotes from different clinics, it is essential to ask detailed questions to understand what is included and what is not. Here are some questions to consider:

    • Is the biopsy fee included in the PGT-A price, or is it separate?
    • Are there additional charges for embryo freezing or storage?
    • Does the price include genetic counseling before and after testing?
    • Are there discounts for testing multiple embryos?
    • What is the turnaround time for results, and does that affect the cost?
    • Are there any hidden fees, such as shipping or administrative charges?

    Potential Additional Costs

    Beyond the basic PGT-A fee, you may encounter other expenses. These can include:

    • IVF cycle costs: PGT-A is usually performed in conjunction with IVF, so you will need to factor in the cost of the IVF cycle itself.
    • Medication: Fertility medications are often not included in PGT-A quotes.
    • Travel and accommodation: If you are traveling to Thailand, you will need to budget for flights, hotels, and local transportation.
    • Follow-up treatments: If you need additional IVF cycles or embryo transfers, these will incur separate costs.

    How to Plan Your Budget

    Since exact prices are not available without a clinic consultation, it is wise to plan for a range. Start by researching clinics and requesting detailed quotes. Then, consider the following steps:

    1. Compare packages: Look at what each clinic includes in its PGT-A package and compare the total cost of IVF plus PGT-A.
    2. Ask about payment plans: Some clinics offer installment options or financing.
    3. Check for hidden fees: Ask for a full breakdown of all charges.
    4. Consider the number of embryos: Estimate how many embryos you might have based on your age and previous IVF history, and ask for a per-embryo price.

    Next Steps

    To get a clear picture of PGT-A costs in Thailand, you will need to contact clinics directly. Prepare a list of questions and ask for a written quote. Remember that the cheapest option is not always the best; consider the clinic’s experience, laboratory standards, and success rates (though success rates are not guaranteed).

  • How to Interpret PGT-A Results from a Thai Lab

    What Is PGT-A and Why Is It Used?

    Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a screening technique used during in vitro fertilization (IVF) to analyze embryos for chromosomal abnormalities. The goal is to identify embryos with the correct number of chromosomes (euploid) before transfer, potentially improving the chances of implantation and reducing the risk of miscarriage or genetic disorders. PGT-A does not test for all genetic conditions; it focuses on chromosome number changes.

    Understanding PGT-A Result Categories

    Thai laboratories typically report PGT-A results in three main categories:

    • Euploid: The embryo has the expected number of chromosomes (46 in humans). These embryos are considered chromosomally normal and are generally prioritized for transfer.
    • Aneuploid: The embryo has missing or extra chromosomes (e.g., trisomy 21, monosomy X). These embryos are unlikely to result in a healthy pregnancy and are usually not recommended for transfer.
    • Mosaic: The embryo has a mixture of euploid and aneuploid cells. The degree of mosaicism (low, medium, high) can affect transfer recommendations. Some low-level mosaic embryos may be considered for transfer if no euploid embryos are available, after genetic counseling.

    How Thai Labs Report PGT-A Results

    Thai labs typically provide a report that includes:

    • Embryo identification number
    • Biopsy date and testing method (e.g., next-generation sequencing)
    • Chromosomal analysis for each chromosome pair
    • Result classification: euploid, aneuploid, or mosaic (with percentage if applicable)
    • Sex chromosome status (if requested)

    Reports may also include a comment on embryo quality and recommendations. It is important to note that reporting formats can vary between laboratories. Always request a copy of the full report and discuss it with your fertility specialist.

    What to Ask Your Doctor About Transferability

    When reviewing your PGT-A results, consider asking your doctor these questions:

    • Which embryos are euploid and recommended for transfer?
    • If mosaic embryos are present, what is the level of mosaicism and what are the potential risks and outcomes?
    • Are there any aneuploid embryos that might be considered for transfer under exceptional circumstances?
    • How does the lab’s classification system affect transfer decisions?
    • What additional testing (e.g., PGT-M for single gene disorders) might be needed?

    Limitations of PGT-A

    PGT-A is a screening tool, not a diagnostic test. It has limitations:

    • It cannot detect all genetic disorders, such as single-gene mutations or structural rearrangements.
    • Mosaicism may be underestimated or overestimated due to biopsy sampling.
    • Euploid embryos do not guarantee pregnancy or a healthy baby; other factors (e.g., uterine environment, embryo quality) also matter.
    • There is a small risk of misdiagnosis or no result from the biopsy.

    Next Steps After Receiving Results

    After reviewing your PGT-A results with your doctor, you may consider:

    • Discussing transfer options for euploid embryos
    • Exploring additional genetic counseling if mosaic or aneuploid results are present
    • Considering further testing (e.g., PGT-M) if a specific genetic condition is a concern
    • Reviewing your IVF cycle plan and timing for frozen embryo transfer

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

    Frequently asked questions

    What does euploid mean in PGT-A results?

    Euploid means the embryo has the correct number of chromosomes (46 in humans). These embryos are considered chromosomally normal and are typically prioritized for transfer.

    Can a mosaic embryo be transferred?

    In some cases, low-level mosaic embryos may be considered for transfer if no euploid embryos are available. This decision should be made after thorough genetic counseling and discussion of potential risks with your doctor.

    How accurate are PGT-A results from Thai labs?

    Thai labs generally use validated technologies like next-generation sequencing, but no test is 100% accurate. There is a small risk of misdiagnosis or no result. Discuss the lab's quality controls and success rates with your clinic.

    Do I need PGT-A for all embryos?

    PGT-A is optional and not recommended for all patients. It is often considered for women of advanced maternal age, those with recurrent pregnancy loss, or previous aneuploidy. Your doctor can help determine if it is appropriate for you.

    What questions should I ask about my PGT-A report?

    Ask your doctor to explain each result category, the level of mosaicism if present, and how the lab's classification affects transfer recommendations. Also inquire about the need for additional testing or genetic counseling.

  • Mosaic PGT-A reports: laboratory thresholds and interpretation questions

    A mosaic PGT-A report needs interpretation by the reporting laboratory and qualified clinical professionals. It is not a whole-embryo cell census or an automatic treatment instruction.

    Report categories depend on the laboratory

    Laboratories can use different thresholds and reporting policies for intermediate copy-number findings. ASRM’s 2023 committee opinion on mosaic PGT-A results (Fertility and Sterility 120:973–982) explains this variation. This source addresses reporting principles; it does not establish what most Thai laboratories do. This page therefore provides no universal low, medium or high percentage cut-offs.

    Request the report’s own rules

    • Which laboratory and assay produced this report?
    • What are its validated reporting thresholds and limitations?
    • Does it report mosaic findings, mask them or classify intermediate findings another way?
    • How are segmental findings and no-result reports distinguished?
    • Which clinician or qualified genetic counsellor will explain the actual finding and available options?

    Keep interpretation separate from an individual decision

    Do not treat a reported percentage as a measured proportion of abnormal cells throughout an embryo or as a personal fetal-risk percentage. Ask the professional team to explain uncertainty, its transfer policy and any pregnancy follow-up discussion using the complete report. A general article cannot decide embryo priority or whether transfer or additional testing is appropriate.
