Introduction
If you are comparing Bangkok fertility clinics for preimplantation genetic testing (PGT), knowing what to look for can help you ask the right questions. PGT is a technology used during IVF to screen embryos for genetic conditions before transfer. Not all clinics offer the same level of service, and the quality of your PGT experience depends on several factors. This article provides a checklist to evaluate PGT offerings, based on publicly available information about selected Bangkok providers. Always confirm details directly with the clinic.
Checklist for Evaluating PGT Services
1. Laboratory Type and Accreditation
The laboratory where embryo biopsies are performed and genetic analysis is done is critical. Look for clinics that have an in-house genetics lab or a partnership with a certified external lab. Accreditation from organizations such as JCI, CAP, or UK NEQAS indicates quality standards. For example, Deep & Harmonicare IVF Center (DHC) holds JCI, ISO 9001, RTAC, CAP, and UK NEQAS certifications. Bumrungrad International Hospital is a large multidisciplinary hospital with integrated services, but its fertility lab details should be confirmed directly.
2. Geneticist Availability
A qualified geneticist should be involved in your case. Some clinics employ a full-time geneticist who can counsel you on test results and implications. Others may send biopsies to an external lab. Ask whether a genetic counselor or reproductive geneticist is available for consultation before and after testing. For instance, Bumrungrad lists Dr. Phattaraphum Phophong with training in reproductive medicine and prenatal genetics. Gift Fertility Clinic names Dr. Waranya Sirithanasarn with 13 years of experience. Confirm who will interpret your results.
3. Biopsy Technique
PGT requires a biopsy of cells from the embryo. The most common technique is trophectoderm biopsy (day 5 or 6 blastocyst stage), which is less invasive than earlier cleavage-stage biopsy. Ask which day the biopsy is performed and whether the clinic uses laser-assisted biopsy for precision. DHC materials list Embryoscope+ and Geri incubators for time-lapse imaging, which may support biopsy timing. Prime Fertility Clinic describes assisted hatching, which is related but not the same as biopsy.
4. Success Rates
Success rates for PGT are often reported as embryo transfer success rates (pregnancy per transfer) or live birth rates. Be cautious: success depends on many factors including maternal age, embryo quality, and lab conditions. DHC’s 2026 hospital profile reports a 78% average embryo-transfer success rate for 2025 (approximately 80%), but this is not an individual prediction. Other clinics may not publish their PGT-specific rates. Always ask for clinic-specific data and understand that published rates are averages.

Questions to Ask Before Choosing a Clinic
- Is the PGT performed in an on-site lab or sent to an external facility? What accreditations does the lab hold?
- Who will perform the embryo biopsy? What technique is used (trophectoderm vs. cleavage-stage)?
- Is a geneticist or genetic counselor available to discuss results and implications?
- What are the clinic’s success rates for PGT cycles? How are they calculated (per biopsy, per transfer, per live birth)?
- What is included in the quoted price? Does it cover the biopsy, genetic analysis, and any follow-up counseling?
- How are embryos cultured and monitored? Are time-lapse incubators used?
Understanding PGT Limitations
PGT can reduce the risk of transferring an embryo with a specific genetic condition, but it does not guarantee a healthy baby. Embryos can be mosaic (mix of normal and abnormal cells), and testing may have false positives or negatives. No test can screen for all genetic disorders. Discuss these limitations with your doctor.
Conclusion
When reviewing Bangkok fertility clinics for PGT, focus on lab quality, geneticist involvement, biopsy technique, and transparent success data. Use the checklist above to guide your research. For more information, see our hospitals page, hospital rankings, and editorial policy.
Frequently asked questions
What is PGT and why is it important?
PGT (preimplantation genetic testing) screens embryos created through IVF for genetic conditions before transfer. It can help reduce the risk of passing on certain inherited disorders, but it does not guarantee a healthy pregnancy or baby.
What should I look for in a PGT lab?
Look for accreditation (e.g., JCI, CAP, UK NEQAS), an in-house or partnered genetics lab, and experienced embryologists. Ask about biopsy technique (trophectoderm is standard) and whether time-lapse incubators are used.
How do I know if a clinic's success rates are reliable?
Ask for PGT-specific success rates (e.g., live birth per biopsied embryo) and how they are calculated. Be cautious of averages that may not reflect your individual situation. Verify with the clinic directly.
Is a geneticist available at Bangkok fertility clinics?
Some clinics have geneticists on staff or available for consultation. For example, Bumrungrad lists a doctor with training in prenatal genetics. Always confirm availability and whether counseling is included.
