At a glance
A practical, step-by-step guide to help you prepare for your PGT-A embryo biopsy day in Thailand, including what to ask your clinic and what to expect.
If you are scheduled for a PGT-A biopsy in Thailand, you may feel a mix of hope and nervousness. This guide explains what happens on the day of the biopsy and provides a practical checklist to help you feel prepared. Remember, your fertility clinic is your best source of specific instructions, so use this as a general framework and confirm details with your care team.
At a Glance: Your Biopsy Day Checklist
- Confirm your appointment time and location with your clinic.
- Ask about any preparation steps required from you (e.g., medications, fasting).
- Understand that the biopsy is performed on embryos in the lab, not on your body.
- Plan for a waiting period after the biopsy while embryos are sent for testing.
- Prepare questions about timing, results, and next steps.
Understanding the PGT-A Biopsy Process
PGT-A (preimplantation genetic testing for aneuploidy) is a test that checks embryos for the correct number of chromosomes. During the biopsy, a few cells are removed from the outer layer of the embryo (trophectoderm) that will become the placenta. This is done in the embryology laboratory, not in your body. The biopsied cells are then sent to a genetics lab for analysis, which can take several days to weeks.
It is important to know that PGT-A is not a guarantee of a successful pregnancy or a healthy baby. It is a screening tool that can help your doctor choose which embryo to transfer, but it does not eliminate all risks.
Before the Biopsy Day: What to Ask Your Clinic
In the days leading up to your biopsy, contact your clinic to clarify the following:
- Exact timing: When is the biopsy scheduled? Is it on a specific day after egg retrieval?
- Preparation requirements: Do you need to take any medications, such as antibiotics or progesterone, before the biopsy? Are there any dietary restrictions?
- Who performs the biopsy: Ask about the embryologist’s experience and the lab’s protocols.
- How you will be informed: Will the clinic call you with results, or will you have a follow-up appointment?
- Costs: Confirm what is included in the biopsy fee and what additional costs may arise (e.g., genetic testing, shipping).
On the Day of the Biopsy: Step-by-Step
1. Confirm Logistics
Double-check your appointment time and location. If you are traveling from another city or country, ensure you have reliable transportation and have planned for any traffic delays. Keep your clinic’s contact number handy.
2. Follow Pre-Procedure Instructions
Your clinic may give you specific instructions, such as taking certain medications or avoiding food or drink for a few hours. Follow these exactly. If you are unsure, call the clinic.
3. Arrive at the Clinic
Plan to arrive a little early to complete any paperwork or to ask last-minute questions. You may not need to do anything physically on this day, as the biopsy is performed in the lab. However, you may need to sign consent forms if you haven’t already.
4. Understand the Lab Process
While the biopsy is happening, you will likely wait. The embryologist will use a microscope and a fine needle to remove a few cells from each embryo. This process is delicate and requires skill. The embryos are then placed back into culture while the biopsied cells are prepared for genetic analysis.
5. Ask About Next Steps
Before you leave, ask the clinic how and when you will receive the results. Typically, results are available within a week or two, but this can vary. Ask whether you will have a consultation to discuss the results and what your options are.
What to Expect After the Biopsy
After the biopsy, your embryos will continue to develop in the lab. The biopsied cells are sent to a genetics laboratory for analysis. You may not need to stay in Thailand during this waiting period, but you should discuss this with your clinic. Some patients choose to return home and come back for a frozen embryo transfer later.
It is normal to feel anxious while waiting for results. Try to focus on self-care and stay in touch with your clinic for updates.
Questions to Ask Your Clinic About Biopsy Day
- How many embryos are expected to be biopsied?
- What is the experience of the embryologist performing the biopsy?
- How long will the biopsy take?
- Will I be sedated or experience any discomfort? (Usually, the biopsy is not painful because it is done on embryos, not on you.)
- How will I be notified of the results, and how long will it take?
- What are the next steps after the results are available?
Your Next-Step Checklist
- Confirm your biopsy appointment details with your clinic.
- Ask about any preparation steps required from you.
- Plan your travel and accommodation if you are coming from afar.
- Prepare a list of questions for your clinic.
- After the biopsy, ask about the expected timeline for results.
- Discuss with your doctor what the results might mean for your treatment plan.

Frequently asked questions
Is the PGT-A biopsy painful?
No, the biopsy is performed on embryos in the laboratory, not on your body. You will not feel any pain during the procedure. You may have some anxiety, but the process itself is not physically uncomfortable.
How long does the PGT-A biopsy take?
The biopsy procedure itself is relatively quick, but the overall time can vary depending on the number of embryos. Your clinic can give you a more specific estimate based on your situation.
When will I get the PGT-A results?
Results typically take several days to a few weeks, as the biopsied cells must be sent to a genetics laboratory for analysis. Your clinic will provide you with a more precise timeline.
Do I need to stay in Thailand while waiting for PGT-A results?
It depends on your clinic's recommendations and your personal circumstances. Some patients choose to return home and come back for a frozen embryo transfer later. Discuss your travel plans with your clinic.
