How Much Does PGT Genetic Screening Cost in Thailand? Cost Breakdown & Influencing Factors
Last week, a 38-year-old patient with an AMH of 1.2 ng/mL and a report of balanced chromosomal translocation asked: If I go to Thailand for third-generation IVF, how much will PGT genetic screening actually cost? This question seems simple, but answering it requires breaking down at least five variables: technology type, number of embryos, testing platform, whether genetic counseling is involved, and the subsequent freezing cycle. This article directly answers this question and provides a complete framework for cost evaluation.
Direct Answer: Cost of PGT Genetic Screening
The cost of PGT genetic screening in Thailand is calculated per embryo, with no unified package price. The main differences come from the screening objectives and the testing technology platform.
| Screening Type | Cost per Embryo (THB) | Common Applications |
|---|---|---|
| PGT-A (Aneuploidy Screening) | 8,000 - 12,000 | Advanced maternal age, recurrent implantation failure, recurrent miscarriage |
| PGT-M (Monogenic Disease Screening) | 15,000 - 25,000 | Thalassemia, spinal muscular atrophy, hereditary cancers, etc. |
| PGT-SR (Structural Rearrangement Screening) | 12,000 - 18,000 | Carriers of balanced translocations, Robertsonian translocations, inversions, etc. |
Using the biopsy of 5-8 blastocysts as an example, the total cost for PGT-A is approximately 40,000-60,000 THB, for PGT-M approximately 75,000-150,000 THB, and for PGT-SR approximately 60,000-110,000 THB. Additional costs for biopsy, genetic counseling, and embryo freezing must be calculated separately. It is recommended to budget 80,000-150,000 THB for the entire genetic screening phase.
Breakdown of Cost Influencing Factors
Differences in Screening Technology Platforms
Mainstream testing platforms in Thailand include NGS (Next-Generation Sequencing), aCGH (Array Comparative Genomic Hybridization), and FISH (Fluorescence In Situ Hybridization). The NGS platform offers high throughput and resolution at the Mb level, with moderate cost, making it the primary choice for PGT-A and PGT-SR. aCGH provides higher resolution, capable of detecting small fragment deletions and duplications, with a cost increase of about 20%. FISH only targets specific chromosomes, has the lowest cost but limited information, and is gradually being phased out.
Number of Embryos and Timing of Biopsy
Biopsy occurs at the blastocyst stage (day 5-6), and only embryos that form blastocysts can be biopsied. It is common to retrieve 10 eggs and end up with 4-6 blastocysts, meaning the number of biopsies is naturally limited. Some clinics charge a base fee for the first 3-4 embryos, with a tiered price for additional ones. The unit price for fewer than 5 embryos is usually higher than the package price for 6 or more embryos.
Genetic Counseling and Family Verification
PGT-M and PGT-SR require prior genetic mutation mapping and family linkage analysis of the proband (the patient or affected family member). This step costs approximately 3,000-8,000 RMB in China or about 10,000-20,000 THB in Thailand. Genetic counseling fees are separate, around 3,000-5,000 THB per session, typically requiring 1-2 consultations.
Easily Overlooked Detail: Embryo freezing fees are charged annually. Genetic screening results typically take 3-6 weeks to be issued, during which time the embryos are frozen. The resulting freezing costs are often omitted from the budget. Embryo freezing in Thailand costs about 5,000-10,000 THB per year, with some clinics charging per straw.
Pricing Logic of Different Hospitals and Laboratories
Laboratories with PGT testing qualifications in Thailand are mainly located in Bangkok, operating as either independent laboratories or hospital-owned labs. Independent labs like Genea and iGenix accept samples from multiple clinics, offer transparent pricing, and charge per embryo. Hospital-owned labs such as BNH, Samitivej, Jetanin, and EK often bundle genetic screening costs with ovarian stimulation, egg retrieval, and embryo culture into a "third-generation IVF package," but the PGT cost within the package is similar to that of independent labs.
The main differences come from additional services: whether genetic counseling, embryo freezing, and result interpretation reports are included. The lowest-priced packages often require separate payment for biopsy fees (approximately 5,000-8,000 THB per embryo), while higher-priced packages may already include the biopsy procedure.
| Pricing Model | Representative Institution Type | Total Cost for 5 Embryos (THB) | Notes |
|---|---|---|---|
| Per Embryo Billing | Independent Laboratory | 45,000-60,000 | Biopsy and result interpretation fees are extra |
| Third-Generation IVF Package Price | General Hospital | 55,000-80,000 | Includes biopsy and freezing, but with embryo number limits |
| Tiered Billing (First 3 + Excess) | High-End Clinic | 50,000-70,000 | Lower unit price for excess, suitable for those with many embryos |
Common Pitfalls to Avoid
- Low-Price Traps: A "20,000 THB all-inclusive PGT" usually only covers the biopsy fee, with testing fees charged separately per embryo. Before signing a contract, confirm whether the fee covers embryo biopsy, genetic counseling, result reports, and embryo freezing.
- Genetic Screening in "Success Guarantee" Packages: Some packages claim to include PGT, but only PGT-A. If PGT-M or PGT-SR is needed, additional payment is required, and the paid PGT-A fee is non-refundable.
- Proband Sample Requirements: PGT-M requires blood samples from both parents and an affected family member. If the proband is in China, blood sample transport or completing family verification in China needs to be arranged in advance. This time and logistics cost are easily overlooked.
- Handling Mosaic Results: About 5-10% of embryos may be mosaic (some cells normal, some abnormal), requiring additional genetic counseling and secondary testing, costing approximately 3,000-5,000 THB per test.
Costs and Procedures for Special Cases
Carriers of Balanced/Robertsonian Translocations
These cases require PGT-SR, which is more expensive than PGT-A. The key is distinguishing between balanced translocation carriers and completely normal embryos. This requires family linkage analysis or breakpoint mapping, adding 2,000-4,000 THB in analysis costs. The probability of obtaining a transferable embryo is typically only 20-35%, meaning more blastocysts are needed to get a normal embryo, indirectly increasing biopsy and testing costs.
Families with Monogenic Diseases (Thalassemia, SMA, Hereditary Deafness, etc.)
PGT-M requires designing probes for specific gene mutations. The upfront primer design and validation cost is about 8,000-12,000 THB, regardless of the number of embryos tested. If the family has multiple mutation sites, the probe design cost is higher. During embryo testing, each site is charged separately, increasing the cost by 30-50%.
Advanced Maternal Age with Diminished Ovarian Reserve
For patients with AMH below 1.0 ng/mL and an antral follicle count of fewer than 6, the number of eggs retrieved is low, and the blastocyst formation rate is low, potentially resulting in only 2-3 embryos for testing. Although the total testing cost is lower, the unit cost per embryo for genetic screening is higher, and the risk of having an insufficient number of transferable embryos increases. Some clinics have a minimum charge for fewer than 4 embryos submitted for testing, around 30,000-40,000 THB.
Doctor's Perspective: Cost Does Not Equal Success Rate
"Patients often directly link PGT cost with success rates, thinking that spending more on comprehensive screening guarantees success," mentioned a reproductive doctor with 8 years of practice in Thailand. "But PGT is a screening tool, not a treatment. For young women with normal chromosomes, PGT-A does not improve the live birth rate per single transfer and may even result in embryo loss due to the biopsy procedure. Whether the cost is worthwhile depends on the patient's specific indications."
From a medical perspective, the groups that most clearly benefit from PGT include: women aged ≥38, those with recurrent implantation failure (≥3 times), recurrent miscarriage (≥2 times), known carriers of chromosomal structural rearrangements or monogenic diseases. For patients without these indications, the cost of PGT is an unnecessary expense.
Frequently Asked Questions
Q: Is PGT cheaper in Thailand than in China?
A: For the genetic screening step alone, costs in Thailand are similar to those in first-tier city reproductive centers in China. PGT-A in China costs about 3,000-5,000 RMB per embryo, while in Thailand it's about 8,000-12,000 THB (approximately 1,600-2,400 RMB), making Thailand slightly cheaper. However, the gap narrows when adding biopsy, freezing, and genetic counseling fees. The core reason for choosing Thailand is the more flexible requirements for medical indications and documentation, not a price advantage.
Q: Can PGT-A and PGT-M be done together? How is the cost calculated?
A: Yes. Performing both aneuploidy and monogenic disease screening on the same blastocyst costs the base PGT-A fee plus an additional fee for PGT-M, typically an extra 8,000-12,000 THB per embryo, totaling approximately 18,000-25,000 THB per embryo.
Q: How long do I need to pay embryo freezing fees?
A: In Thailand, frozen embryos are typically renewed annually, costing about 5,000-10,000 THB per year. If genetic screening results are normal but transfer is not immediate, freezing fees must be paid continuously. Some clinics offer discounts for paying 3-5 years upfront, saving 15-25% on costs.
Q: I have no family history of genetic diseases. Do I only need PGT-A?
A: If you are <38 years old, with no history of recurrent miscarriage or recurrent implantation failure, the necessity of PGT-A is limited. Although the cost is not high, the potential risks of the biopsy procedure (approximately 1-2% embryo damage rate) and the additional freezing cycle are factors to consider.
What You Need to Prepare
- Genetic Reports: If PGT-M or PGT-SR is involved, provide the proband's genetic test report and blood or DNA samples from both parents.
- Genetic Counseling Records: Domestic genetic counseling reports can serve as a reference, but Thai laboratories usually require new genetic counseling to confirm the testing plan.
- Expected Number of Embryos: Ovarian reserve assessment indicators like AMH, FSH, and antral follicle count are used to estimate the number of blastocysts available for biopsy, thereby calculating the total genetic screening cost.
- Time Planning: Probe design for PGT-M takes about 4-6 weeks, family analysis for PGT-SR about 2-4 weeks, and obtaining test results after biopsy about 3-6 weeks. The entire cycle from ovarian stimulation to obtaining a report on transferable embryos typically takes 2-3 months.
Observations from a Practitioner
After handling over 300 cases of PGT in Thailand, I've found that budget overruns mainly occur in two areas: first, the number of embryos is lower than expected, leading to higher unit costs; second, secondary testing is needed for mosaicism or variants of uncertain significance (VOUS). It is recommended to reserve 20-30% flexibility in the budget. Additionally, some patients skip family verification for PGT-M to save costs and test embryos directly in Thailand. This approach may fail to distinguish between carriers and normal embryos, wasting both embryos and testing fees. Proband genetic mapping is an indispensable preliminary step for PGT-M.
Risk Reminder: PGT genetic screening cannot 100% rule out all genetic risks. The accuracy for monogenic disease screening is about 95-98%, and for chromosomal screening, about 99-99.5%. After a normal screening result, there is still a residual risk of about 0.5-2% upon transfer. Furthermore, the potential impact of the biopsy procedure on embryo developmental potential is not yet fully conclusive. It is essential to fully understand the technical limitations before deciding to undergo PGT.
