How to Read a PGT Report from a Thai Clinic: A Plain-English Guide for International Patients

If you have received a PGT report from a clinic in Thailand, the first step is to understand what the report is and what it is not. A PGT report summarises laboratory findings from a small sample of cells taken from an embryo. It is a technical document, not a diagnosis of your health or a guarantee of any outcome. This guide explains the common structure and terminology you may see, the categories of results that are typically reported, and the questions that can help you and your clinician interpret the findings in your specific situation. It does not replace a conversation with your treating clinic or a qualified genetics professional.

At a glance

• PGT reports describe laboratory findings from embryo samples; they do not predict pregnancy or child health with certainty.
• Different PGT types (PGT-A, PGT-M, PGT-SR) answer different questions and use different reporting language.
• Result categories such as “euploid,” “aneuploid,” “mosaic,” and “inconclusive” have specific meanings that your clinician should explain in context.
• Reports may include technical caveats, limitations, and recommendations for confirmatory testing or genetic counselling.
• Ask your clinic for a translated or explained version of the report if the original is not in a language you read comfortably.

What a PGT report is — and what it is not

A PGT report is a laboratory summary. It typically describes the type of test performed, the sample analysed, the methodology used, and the findings for each embryo tested. It may also include quality indicators, limitations, and a disclaimer about the scope of the test.

It is not a diagnosis of you or your partner. It is not a guarantee that an embryo will implant, develop normally, or result in a healthy child. It is not a complete picture of all possible genetic conditions. And it is not a substitute for genetic counselling, especially when a specific inherited condition is involved.

Because PGT is a screening or diagnostic adjunct, not a treatment, the report should always be interpreted alongside your clinical history, the reason PGT was recommended, and the limitations of the technology used.

The three main types of PGT and what their reports cover

PGT is an umbrella term. The type of PGT performed determines what the report can and cannot tell you. The table below outlines the general focus of each type. Your clinic can confirm which type was used in your case.

PGT type	General focus	Typical report content
PGT-A	Screening for extra or missing chromosomes (aneuploidy)	Chromosome copy number findings per embryo; may include mosaic or inconclusive categories
PGT-M	Testing for a specific inherited condition known to be present in the family	Presence or absence of the specific gene variant tested; may include affected, carrier, or unaffected categories
PGT-SR	Testing for structural chromosome rearrangements	Findings related to the specific rearrangement; may include balanced, unbalanced, or inconclusive categories

Some reports combine more than one type, for example PGT-A plus PGT-M. In that case, the report may have separate sections for each test. Ask your clinic which sections apply to your embryos.

Common sections you may see in a PGT report

Report formats vary by laboratory and clinic, but many include the following sections. The exact headings may differ, and some reports may omit sections that are not relevant to your test.

• Patient and sample identification: Your name or identifier, the clinic’s identifier, the date of the biopsy, and the date the report was issued.
• Test requested: The specific PGT type and any additional tests ordered.
• Methodology: A brief description of the laboratory technique used, such as the platform or the number of cells analysed. This section may include technical limitations.
• Results table: A list of embryos tested, often identified by a code or number, with the finding for each. This is usually the core of the report.
• Interpretation or comments: A narrative explanation of the findings, including any caveats or recommendations.
• Limitations and disclaimer: A statement about what the test cannot detect, the possibility of false results, and the need for clinical correlation.
• Recommendations: Suggestions for next steps, such as genetic counselling, confirmatory testing, or discussion with your clinician.

If any section is unclear or missing, ask your clinic for clarification. You are entitled to understand the information that affects your care.

Understanding result categories

The language used in PGT reports can be technical. Below are some common categories and what they generally mean. Your clinician should explain how these categories apply to your specific embryos and your treatment plan.

Euploid

This term generally means the embryo has a typical number of chromosomes for its stage of development, based on the cells sampled. It does not guarantee implantation or a healthy pregnancy. It means the test did not detect an abnormal chromosome number in the sample.

Aneuploid

This term generally means the embryo has an abnormal number of chromosomes in the sample. Aneuploidy can involve an extra chromosome (trisomy), a missing chromosome (monosomy), or more complex patterns. The report may specify which chromosome(s) are involved. The clinical significance depends on the specific finding and is best discussed with your clinician.

Mosaic

Mosaicism means the sample contains a mix of cells with different chromosome numbers. The report may describe the percentage of cells affected or use terms like “low-level” or “high-level” mosaic. Mosaic results are often complex, and their interpretation depends on the specific chromosomes involved and the proportion of affected cells. Your clinic may recommend genetic counselling to discuss the implications.

Inconclusive or no result

Sometimes the laboratory cannot obtain a clear result from the sample. This may be due to technical factors, insufficient DNA, or other reasons. An inconclusive result does not mean the embryo is abnormal; it means the test did not provide a definitive answer. Your clinic may discuss options such as re-biopsy, re-testing, or proceeding without a result, depending on your situation.

Carrier or affected (for PGT-M)

For PGT-M, the report may use terms like “affected,” “carrier,” or “unaffected” in relation to the specific condition tested. These terms describe the presence or absence of the gene variant in the sample. The meaning for your family depends on the inheritance pattern of the condition and should be explained by a genetics professional.

Why the same result can be interpreted differently

PGT results are not interpreted in isolation. The same laboratory finding may lead to different clinical recommendations depending on:

• The reason PGT was performed (for example, advanced maternal age, recurrent pregnancy loss, or a known familial condition).
• The number and quality of embryos available.
• Your reproductive history and previous treatment outcomes.
• The specific chromosomes or gene variants involved.
• The limitations of the testing platform used.
• Your personal values and preferences, which may be informed by genetic counselling.

This is why a report should not be read as a standalone verdict. It is one piece of information among many that your care team will consider.

Questions to ask your clinic about your PGT report

Bring your report to your next consultation and consider asking the following questions. You may want to request a translated copy or an explanation in a language you understand well.

1. Which type of PGT was performed, and what was it looking for?
2. Can you explain the result for each embryo in plain language?
3. What do the terms “euploid,” “aneuploid,” “mosaic,” or “inconclusive” mean for my specific embryos?
4. What are the limitations of this test for my situation?
5. Are there any findings that suggest I should consider genetic counselling?
6. How might these results affect the options available to me?
7. What would you recommend as next steps, and what alternatives exist?
8. Can I have a copy of the full report, including any technical appendices?
9. Is there a genetics professional or counsellor I can speak with?
10. What costs, if any, are associated with further testing or counselling?

Write down the answers. If something is still unclear, ask again. It is reasonable to take time to understand the information before making decisions.

Limitations of PGT and report interpretation

PGT is a powerful tool, but it has limitations. No test can detect every possible genetic or chromosomal issue. Some conditions are not detectable by the methods used. Mosaic results can be difficult to interpret because the sample may not represent the whole embryo. Technical errors, though uncommon, can occur. And a “normal” result does not guarantee a healthy pregnancy or child.

Because of these limitations, PGT reports should always be interpreted by qualified professionals in the context of your overall care. If you are considering PGT or have received a report, ask your clinic about the specific limitations of the test you used.

Next steps for international patients

If you are reviewing a PGT report from a clinic in Thailand, here is a short checklist to help you move forward:

• Request a full copy of the report, including any technical sections, in a language you read comfortably.
• Ask your clinic to schedule a consultation to explain the results.
• Prepare your questions in advance, using the list above as a starting point.
• Ask whether genetic counselling is available, either at the clinic or remotely.
• Take notes during the consultation and ask for clarification on any point you do not understand.
• Consider seeking a second opinion if you feel uncertain or if the findings are complex.
• Keep all reports and correspondence in a safe place for your records.

Understanding your PGT report is a process, not a single event. You are entitled to clear explanations and to make decisions at your own pace. For more general information about PGT in Thailand, you can explore our PGT in Thailand page, browse our guides, or check our FAQ section.

Frequently asked questions

What does an inconclusive PGT result mean?

An inconclusive result means the laboratory could not obtain a clear finding from the sample. This can happen for technical reasons, such as insufficient DNA or poor sample quality. It does not mean the embryo is abnormal. Your clinic may discuss options such as re-testing or proceeding without a result, depending on your situation.

Can a PGT report tell me whether my embryo will implant?

No. A PGT report describes laboratory findings from a sample of cells. It cannot predict whether an embryo will implant, develop normally, or result in a healthy child. Implantation depends on many factors, including embryo quality, uterine environment, and maternal health. Your clinician can explain how the report fits into your overall treatment plan.

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

PGT-A screens for extra or missing chromosomes (aneuploidy). PGT-M tests for a specific inherited condition known to be present in the family. PGT-SR tests for structural chromosome rearrangements. Each type uses different laboratory methods and produces different types of reports. Your clinic can confirm which type was used in your case.

Should I get genetic counselling after receiving a PGT report?

Genetic counselling can be helpful, especially if your report shows a mosaic result, a specific chromosome abnormality, or a finding related to an inherited condition. A genetics professional can explain the implications for you and your family and help you understand your options. Ask your clinic whether genetic counselling is available.

Can I get my PGT report translated into English?

Many clinics in Thailand can provide reports or explanations in English, but this varies. If your report is not in a language you read comfortably, ask your clinic for a translated copy or for a consultation with an interpreter. It is important that you understand the information that affects your care.
