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.

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.
