PGT Report Interpretation Checklist for Thailand: A Plain-English Guide for International Patients

Reading a PGT report from a Thai clinic can feel like decoding a foreign language, especially when you are far from home and the results arrive by email. This checklist helps you review the report calmly, understand common terms such as euploid, aneuploid and mosaic, and prepare focused questions for a genetic counselor or clinician. It does not tell you what your results mean for your own treatment. Only a qualified professional who knows your history can do that. Use this guide to organize your reading, not to replace medical advice.

At a glance

• PGT reports describe laboratory findings about embryos, not a guarantee of pregnancy or a healthy child.
• Common result categories include euploid, aneuploid, mosaic and inconclusive or no result.
• Check that the report identifies the clinic, laboratory, patient, cycle and date.
• Look for the PGT type: PGT-A, PGT-M or PGT-SR.
• Write down your questions before speaking with a genetic counselor or clinician.
• Ask how the clinic will explain the report to you and whether a translated version is available.

What a PGT report is and what it is not

Preimplantation genetic testing (PGT) is a laboratory test performed on cells taken from an embryo during IVF. The report summarizes what the laboratory observed. It is not a diagnosis of a future child, and it cannot promise that a transferred embryo will implant, develop normally or result in a live birth. PGT also cannot rule out all genetic conditions, because testing looks at specific things and has technical limits.

There are different types of PGT. PGT-A looks at the number of chromosomes in an embryo. PGT-M looks for a specific inherited condition that runs in a family. PGT-SR looks at structural chromosome rearrangements. Your report should state which type was performed, because the meaning of the results depends on the test.

Checklist: details to confirm on the first page

Before you read the results, confirm that the report belongs to you and your cycle. Missing or mismatched identifiers are a reason to contact the clinic before drawing any conclusions.

• Patient name and date of birth, or another unique identifier.
• Partner or donor information, if relevant to your case.
• Clinic name and laboratory name.
• Cycle number or embryo cohort identifier.
• Date of embryo biopsy and date the report was issued.
• Type of PGT performed: PGT-A, PGT-M or PGT-SR.
• Method used, if stated, such as the technology platform or whether the lab used a fresh or thawed sample.
• Number of embryos tested and number with a result.
• Whether any embryos were not tested or gave no result.

If any of these details are unclear, ask the clinic to clarify them in writing. A report that cannot be linked confidently to your cycle is difficult to interpret.

Understanding the main result categories

PGT reports often use a small set of terms. The exact wording varies by laboratory, so always ask the clinic to explain the terms used in your report.

Term	Plain-English meaning	What it does not tell you
Euploid	The laboratory found the expected number of chromosomes for the type of test performed.	It does not guarantee implantation, pregnancy or a healthy child.
Aneuploid	The laboratory found an extra or missing chromosome, or another chromosome number difference.	It does not describe every possible feature of that embryo, and it does not predict how any future pregnancy would develop.
Mosaic	The laboratory found a mix of cells with different chromosome patterns in the sample.	It does not mean the embryo will definitely develop in a particular way. Mosaic results are often discussed case by case.
Inconclusive or no result	The laboratory could not produce a clear result for that embryo.	It does not mean the embryo is abnormal. It means the test did not give a clear answer.
Affected or unaffected (PGT-M or PGT-SR)	The laboratory found or did not find the specific genetic change being tested for.	It does not rule out other genetic conditions that were not part of the test.

Some reports include a percentage or a confidence note next to a mosaic result. These details can be technical. Ask the laboratory or your clinician to explain what the number means for your report rather than interpreting it yourself.

Checklist: questions to ask about each embryo result

For every embryo listed, you can note the result and then ask the clinic these questions. The answers help you understand the report without turning it into a self-diagnosis.

1. What does this result mean in plain language for this specific embryo?
2. Was the result clear, borderline or inconclusive?
3. If the result is mosaic, how does the clinic usually discuss mosaic results with patients?
4. Does the report include a recommendation, or is the decision left to me and my clinician?
5. Are there any embryos with no result, and what are the options for those embryos?
6. How does this result fit with the rest of my IVF cycle information?
7. What would you want me to understand before I decide anything?

PGT-A, PGT-M and PGT-SR: why the type matters

The same word can carry different weight depending on the test. A PGT-A report is usually about chromosome number across the embryo. A PGT-M report is usually about a specific inherited condition that was known before testing. A PGT-SR report is usually about a structural rearrangement that was identified in a parent or donor.

Because of these differences, a result that looks simple on paper may need a more detailed explanation. For example, a PGT-M result may say an embryo is unaffected for the condition tested, but that does not mean all genetic risks are excluded. A PGT-A result may say an embryo is euploid, but that does not guarantee a pregnancy. Ask your clinician to explain the scope and limits of the specific test you had.

Limitations to keep in mind

PGT is a screening and diagnostic laboratory tool with technical limits. It cannot detect every possible genetic or health issue. It cannot predict how an embryo will develop after transfer. It cannot guarantee a successful pregnancy, a live birth or a healthy child. Some results are uncertain, and some embryos may be reported as mosaic or inconclusive.

PGT is also not necessary or suitable for every patient or every IVF cycle. Whether PGT is appropriate depends on your medical history, your reasons for testing and the advice of your treating clinician. A PGT report is one piece of information among many, not a final answer.

Preparing for your conversation with a genetic counselor or clinician

Before your appointment, organize your questions in writing. If the report is in Thai or another language, ask the clinic whether an English version or a translated summary is available. If you are joining by phone or video, confirm the time zone and whether an interpreter can be arranged.

• Ask who will explain the report: a genetic counselor, a clinician or both.
• Ask whether the laboratory that performed the test can be contacted for technical questions.
• Ask how the clinic handles results that are mosaic or inconclusive.
• Ask what information the clinic needs from you before the discussion.
• Ask for the explanation in writing if you may need to review it later.
• Take notes and repeat back what you understood, so any misunderstanding can be corrected.

Next-step checklist after reading the report

1. Confirm the report belongs to your cycle and that all identifiers match.
2. Note the PGT type and the result for each embryo.
3. Mark any term you do not understand, especially mosaic or inconclusive results.
4. Write down your questions before contacting the clinic.
5. Ask for a conversation with a genetic counselor or clinician.
6. Ask for a written summary or translated explanation if needed.
7. Do not make treatment decisions based only on the report before speaking with your clinician.

Practical notes for international patients

Time zones, language and distance can make report discussions harder. Ask the clinic how they usually share results with international patients, whether they offer a scheduled call, and whether they can provide documents in a language you read comfortably. If you are planning travel or a follow-up cycle, ask what information you should bring to your next appointment. Keep copies of all reports and correspondence in one place.

Costs, visa rules, legal requirements and clinic-specific policies can change. This guide does not state exact prices, documents or legal conclusions. Confirm those details directly with your clinic and, where relevant, with the appropriate authority.

Frequently asked questions

What does euploid mean on a PGT report?

Euploid generally means the laboratory found the expected number of chromosomes for the type of test performed. It does not guarantee that an embryo will implant, lead to a pregnancy or result in a healthy child. Ask your clinician to explain what a euploid result means in your specific situation.

What is the difference between aneuploid and mosaic?

Aneuploid usually means the laboratory found an extra or missing chromosome, or another chromosome number difference. Mosaic usually means the laboratory found a mix of cells with different chromosome patterns in the sample. Mosaic results are often discussed case by case because the meaning can be less clear-cut. A genetic counselor or clinician can explain how these terms apply to your report.

Can I interpret my PGT report without a clinician?

You can read the report and note the terms, but you should not interpret the results on your own. PGT results need to be considered alongside your medical history, the type of test performed and the limits of the laboratory method. A genetic counselor or clinician can help you understand what the report does and does not tell you.

What should I do if my PGT report is inconclusive?

An inconclusive or no-result entry means the laboratory could not produce a clear result for that embryo. It does not automatically mean the embryo is abnormal. Ask your clinic what options exist for embryos with no result and how they usually discuss these situations with patients.

Does PGT guarantee a healthy baby?

No. PGT is a laboratory test with technical limits. It cannot detect every possible genetic or health issue, and it cannot guarantee implantation, pregnancy, live birth or child health. It is one part of IVF care, not a guarantee of any outcome.
