PGT-A in Thailand Your guide to cost, top specialists & hospitals
Chromosomal screening can help guide embryo selection in specific clinical situations. PGT-A is one tool among several, and the decision to use it is best made with your fertility specialist.
What Is PGT-A?
Also known as: Embryo Screening · Preimplantation Genetic Testing for Aneuploidy
PGT-A is a genetic screening test that checks IVF embryos for aneuploidy, the wrong number of chromosomes, before one is transferred. A few cells are taken from the trophectoderm, the outer layer that becomes the placenta rather than the baby, and read with next-generation sequencing across all 23 chromosome pairs. Each embryo is sorted as euploid, aneuploid, or mosaic. Results take one to two weeks, during which the embryos stay safely frozen.
The idea is honest selection. Transferring a chromosomally normal embryo can lift implantation and lower miscarriage risk in some situations, and an early result can spare you transfers with little chance of working. There is nothing for your body to feel or recover from, since the testing happens in the lab.
The evidence is genuinely mixed, and we would rather say so. For most patients it does not reliably raise the odds of taking a baby home from one egg retrieval, and the benefit is clearest with recurrent miscarriage or older maternal age. Whether PGT-A is right for you is a shared decision with your specialist, not a default add-on.
It can address a range of concerns, including:
Am I a Good Candidate for PGT-A?
PGT-A suits patients already going through IVF who want to screen embryos for chromosomal normality before transfer.
PGT-A is an embryo screening test, so suitability depends on your IVF cycle and how you will use the results.
Blastocyst embryos: the test needs embryos that reach the blastocyst stage to biopsy, so it suits cycles producing them.
Freeze and wait: good candidates are willing to freeze all embryos and wait for results before transfer.
Realistic understanding: PGT-A improves embryo selection but does not guarantee pregnancy, and it is not a test for inherited single-gene conditions.
Who is not suitable for pgt-a?
- Under 35 with a strong embryo cohort, where the added benefit is smaller
- Only one or two embryos reach blastocyst, until a biopsy strategy is discussed
- Unclear how mosaic or inconclusive results will be handled
- Expecting it to test for inherited single-gene disorders, which need PGT-M

PGT-A Clinics in Thailand
PGT-A quality depends on embryologist biopsy skill and the genetics laboratory performing the analysis. Both need to be strong.
Leading Fertility Clinics in Bangkok
Our partner clinics have in-house or closely partnered genetics laboratories equipped with NGS platforms for PGT-A analysis. Their embryologists perform trophectoderm biopsies routinely with documented low damage rates. The combination of experienced biopsy technique and reliable analysis produces consistent, actionable results.
Experienced Genetics Teams
PGT-A results require expert interpretation, particularly mosaic results. Our partner clinics provide genetic counselling from qualified professionals who explain the clinical significance of each result and help you make informed decisions. This is not a generic lab report; it is a personalised consultation.
What to Look for in a Clinic
Ask about the clinic's biopsy damage rate (it should be very low). Confirm they use NGS technology, not older aCGH platforms. Check whether genetic counselling is included in the PGT-A package. Ask about turnaround time; one to two weeks is standard. And confirm the clinic handles mosaic results with nuance rather than blanket rejection of all mosaic embryos.
PGT-A Results and Impact on IVF
PGT-A changes the IVF equation by shifting from morphology-based embryo selection to genetics-based selection. Here is the practical impact.
How PGT-A Affects IVF Outcomes
Per-transfer implantation and miscarriage figures often look better when a euploid embryo is selected, particularly with advanced maternal age where aneuploidy rates rise. The more honest measure, however, is cumulative live-birth rate per egg retrieval, which counts every transfer of every embryo from one cycle. On that measure, the STAR trial (2019) found no improvement for unselected patients, and other studies show differences narrow or disappear. The UK HFEA rates PGT-A red for improving the chances of having a baby for most patients on its add-on traffic-light system.1 PGT-A can help avoid transferring embryos with very low implantation potential and may reduce the time to a successful transfer, but it does not reliably increase the chance of taking a baby home from a given egg retrieval for most patients1.
What PGT-A Cannot Do
PGT-A screens for chromosome number, not single-gene disorders (that requires PGT-M). It does not assess embryo quality in terms of mitochondrial function, metabolic activity, or other developmental factors. A euploid embryo still needs a receptive uterine environment and correct transfer timing to implant. PGT-A improves the odds; it does not guarantee success.2
PGT-A Cost in Thailand
Average Cost of PGT-A
PGT-A in Thailand costs between $2,000 and $3,600 for testing of up to eight embryos. Additional per-embryo fees apply above this number. The cost covers genetic counselling, the biopsy procedure, NGS analysis, results consultation, and a written report with recommendations.
Cost Breakdown
The PGT-A fee includes genetic counselling before testing, the embryo biopsy performed by the embryology team, the genetic analysis using next-generation sequencing, a results consultation, and a comprehensive written report. If you have more than eight embryos to test, additional per-embryo fees apply. The IVF cycle itself is priced separately.
What Affects the Price?
The number of embryos tested is the main variable. The base fee typically covers up to eight embryos, with additional charges per embryo above that threshold. If PGT-M (single-gene testing) is combined with PGT-A on the same biopsy, additional fees apply for the PGT-M component. The IVF cycle cost, medication, and embryo freezing are all separate line items.
Cost by PGT-A Type
Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:
- PGT-A for up to 4 embryos: $2,000–$2,500. Biopsy and chromosomal screening of a small embryo cohort
- PGT-A for 5–8 embryos: $2,500–$3,000. Mid-range cohort with per-embryo cost reduction
- PGT-A for 9 or more embryos: $3,000–$3,600. Large cohort testing at the lowest per-embryo rate
Exact pricing is confirmed after your consultation and treatment plan are finalised.
Thailand vs International Price Comparison
PGT-A in Thailand costs 50–70% less than equivalent testing in the US ($5,000–$9,000), Australia (A$4,400–A$8,000), and UK (£4,000–£7,000). Given the significant impact PGT-A has on per-transfer success rates and miscarriage reduction, the lower Thai pricing makes it a practical addition to any IVF cycle rather than an expensive upgrade.
PGT-A Testing Approaches
PGT-A involves two distinct steps: a precise embryo biopsy and sophisticated genetic analysis. Both require specialised expertise and advanced technology.
Trophectoderm Biopsy
Five to ten cells are carefully removed from the trophectoderm, the outer layer of the blastocyst that will become the placenta. This layer is biopsied rather than the inner cell mass, ensuring the embryo itself is unharmed. An experienced embryologist performs the biopsy using a precision laser and micromanipulation tools at the blastocyst stage (day five to six).
- Does not damage the inner cell mass that forms the baby
- Performed at blastocyst stage for maximum accuracy
- Embryos are vitrified immediately after biopsy
- Best for: all PGT-A patients; biopsy is a required step in the process
Next-Generation Sequencing (NGS) Analysis
The biopsied cells are analysed using NGS technology, which reads the DNA to determine the chromosome count across all 23 pairs simultaneously. NGS is the current gold-standard platform for PGT-A, offering high accuracy and the ability to detect mosaicism: embryos with a mix of normal and abnormal cells. Results classify each embryo as euploid, aneuploid, or mosaic.
- Screens all 23 chromosome pairs in a single analysis
- Detects mosaicism and segmental abnormalities
- Results typically available within one to two weeks
- Best for: all PGT-A patients; NGS is the standard analysis platform
PGT-A Techniques
The accuracy of PGT-A depends on biopsy skill and laboratory analysis quality. Both are well-established at Thailand's leading fertility centres.
Biopsy Quality and Embryologist Skill
The biopsy must remove enough cells for reliable analysis without compromising the embryo. This requires a trained embryologist working under magnification with a precision laser. At experienced centres, biopsy of the outer cells has not been shown to harm the embryo. The number of cells taken (typically five to ten) is calibrated to balance analysis accuracy against embryo safety.
- Risk of embryo damage is very low at experienced centres
- Laser-assisted biopsy ensures precision and minimal trauma
- Immediate vitrification after biopsy preserves embryo quality
- Best for: ensuring reliable results without compromising your embryos
Results Interpretation and Genetic Counselling
Each embryo receives one of three results: euploid (normal chromosome count), aneuploid (abnormal), or mosaic (a mix of normal and abnormal cells). Mosaic results require careful interpretation; some low-level mosaic embryos may still be considered for transfer. A genetic counsellor reviews the results with you, explains the implications, and helps you make informed decisions about which embryo to transfer.
- Clear categorisation of each embryo's chromosomal status
- Mosaic results are explained with nuance, not binary yes/no answers
- Genetic counselling provided before and after testing
- Best for: making informed, confident decisions about embryo selection
PGT-A Process Timeline
Embryo Biopsy (Day 5–6)
When your embryos reach blastocyst stage, the embryologist performs the trophectoderm biopsy. This is a laboratory procedure; you are not involved and there is nothing to recover from. Each embryo is vitrified immediately after biopsy to preserve quality while genetic analysis is completed.
Genetic Analysis (1–2 Weeks)
Biopsied cells are sent for next-generation sequencing analysis. Each embryo receives a result: euploid, aneuploid, or mosaic. You can return home during this waiting period; results are delivered remotely.
Results Consultation
Your specialist and genetic counsellor review the results with you. They explain which embryos are suitable for transfer, what the findings mean, and any implications of mosaic results. A clear written report is provided.
Frozen Embryo Transfer
A euploid embryo is thawed and transferred to your prepared uterus in a subsequent FET cycle, a short visit of five to seven days. Transferring a PGT-A-screened euploid embryo can give a higher per-transfer chance of a healthy pregnancy, though the difference in cumulative live-birth rate per egg retrieval is smaller and depends on your clinical situation.
Does PGT-A Require Additional Time in Thailand?
No additional stay is needed beyond your IVF cycle. The biopsy happens during the standard embryo culture period. Results take one to two weeks, during which you can return home. You will return for a frozen embryo transfer (a separate visit of five to seven days) once results confirm a euploid embryo is available.
What Happens If All Embryos Are Aneuploid?
This is a possibility, particularly for women over 40 where aneuploidy rates are higher. If all tested embryos are aneuploid, options include another IVF cycle to produce more embryos, using donor eggs, or other treatment pathways. Knowing the result in advance prevents you from transferring embryos with very low implantation potential, saving time, money, and the emotional toll of an unsuccessful transfer.
Should You Add PGT-A If You Are Under 35?
Evidence for routine PGT-A in younger patients is weak. The STAR trial (2019) found no live-birth improvement per started cycle for unselected patients, and the HFEA rates PGT-A red for improving the chance of a baby for most patients and grey in older women, with the strongest signal in specific clinical contexts such as recurrent miscarriage or repeated implantation failure. For most patients under 35 with a good embryo cohort, PGT-A is unlikely to change whether you take a baby home. It may still be considered to shorten time-to-pregnancy in a specific situation, but it is a shared decision with your specialist, not a default upgrade.
Risks and Limitations of PGT-A
PGT-A is safe and widely used, but it is a screening tool with inherent limitations. Understanding what it can and cannot do is important for setting expectations.
- Small risk of embryo damage during biopsy (rare; biopsy of the outer cells has not been shown to harm the embryo)2
- False positive or false negative results are rare but possible
- Mosaicism may produce complex or inconclusive results
- A biopsy can occasionally fail to amplify enough DNA, leaving an embryo with no result; re-warming and re-biopsy is sometimes possible but adds cost and a small further risk
- Not all embryos reach blastocyst stage and are available for biopsy
- PGT-A does not test for single-gene disorders (PGT-M is needed for that)
- No guarantee of pregnancy even with a euploid embryo
- Testing may reduce the number of embryos available for transfer if many are aneuploid
PGT-A is a screening tool, not a diagnostic guarantee. A small percentage of results may be inconclusive. Genetic counselling is provided before and after testing so you fully understand the benefits, limitations, and implications of your results.
Is PGT-A Safe in Thailand?
Yes. PGT-A is performed at licensed fertility clinics using the same biopsy equipment and NGS platforms found in top genetics laboratories worldwide. Our partner clinics employ experienced embryologists with documented biopsy proficiency and work with accredited genetics labs for analysis. Quality-control measures meet international standards.
How Accurate Is PGT-A?
PGT-A has high accuracy for detecting whole-chromosome aneuploidy, the most common cause of implantation failure and early miscarriage. However, it is not perfect. False positives (an embryo classified as aneuploid that is actually normal) and false negatives (the opposite) can occur, though both are rare. Mosaicism, where a biopsy sample contains a mix of normal and abnormal cells, adds complexity. These limitations are discussed in your genetic counselling session.
What Is a Mosaic Embryo?
A mosaic embryo contains a mixture of chromosomally normal and abnormal cells. Mosaicism is detected in a minority of biopsied embryos, and the reported rate varies widely between laboratories.3 Handling mosaic results is one of the genuinely uncertain areas of PGT-A: the biopsy samples only a few outer cells and may not reflect the inner cell mass, healthy births have been reported from transferred low-level mosaics, and professional guidance such as PGDIS recommendations continues to evolve. It is not a binary keep-or-discard decision. Genetic counselling weighs the level and type of mosaicism against the alternative embryos available to you and the wider clinical picture, and the decision rests with you.
Adding PGT-A to Your IVF Cycle in Thailand
PGT-A fits naturally into your IVF timeline. The biopsy happens during normal embryo culture, and results arrive while you are home between visits.
How PGT-A Fits Into Your IVF Schedule
The biopsy is performed on day five or six of embryo culture, within your standard IVF stay. Embryos are vitrified immediately after biopsy. You can return home while results are processed over one to two weeks. Once results confirm a euploid embryo, you return for a frozen embryo transfer, a separate visit of five to seven days.
Is PGT-A Worth It for Your Situation?
PGT-A adds cost but can save money overall by reducing the number of unsuccessful transfers. It is most clearly beneficial for women over 35, those with recurrent miscarriage, and those who have experienced repeated implantation failure. For younger patients with multiple good-quality embryos, the added value is smaller, but the confidence of knowing you are transferring a chromosomally normal embryo may still be worthwhile.
Combining PGT-A with PGT-M
If you carry a known genetic condition, PGT-M (testing for a specific gene) can be performed on the same biopsy as PGT-A. This screens embryos for both chromosomal abnormalities and the specific inherited condition simultaneously. The combined approach gives you the most comprehensive information about each embryo before transfer.
