How to Verify PGT Lab Accreditation in Thailand: A Patient Checklist

When you are considering preimplantation genetic testing (PGT) in Thailand, one of the most important steps is verifying that the laboratory meets recognized quality and accreditation standards. Accreditation is a formal process by which an independent body evaluates a laboratory against specific standards. This checklist will help you ask the right questions and look for the right evidence when evaluating PGT labs in Thailand.

At a Glance: What to Check

• Look for official accreditation from recognized international or national bodies.
• Ask for the laboratory’s accreditation certificate and check its scope.
• Inquire about participation in external quality assessment (EQA) programs.
• Ask about the lab’s quality management system and standard operating procedures.
• Confirm that the lab follows strict protocols for sample handling and reporting.

Understanding PGT and Laboratory Accreditation

PGT is a set of genetic tests performed on embryos created through in vitro fertilization (IVF) before transfer. There are several types, including PGT-A (aneuploidy screening), PGT-M (monogenic disorders), and PGT-SR (structural rearrangements). The accuracy and reliability of these tests depend heavily on the laboratory’s technical expertise and quality controls.

Accreditation is a voluntary process that demonstrates a laboratory meets certain standards. In Thailand, laboratories may seek accreditation from international bodies such as the College of American Pathologists (CAP) or the Joint Commission International (JCI), or from national bodies like the Thai Bureau of Laboratory Quality Standards. Accreditation is not a guarantee of a specific outcome, but it indicates that the lab has been evaluated by an independent organization.

Checklist for Verifying PGT Lab Accreditation

1. Check for Official Accreditation

Ask the clinic or laboratory directly for their accreditation certificate. Look for the name of the accrediting body, the date of issue, and the expiration date. Accreditation is typically time-limited, so ensure the certificate is current.

2. Verify the Scope of Accreditation

Accreditation may cover specific tests or procedures. Confirm that the accreditation includes the specific PGT services you are considering, such as PGT-A, PGT-M, or PGT-SR. The scope should be clearly stated on the certificate.

3. Inquire About External Quality Assessment (EQA)

EQA programs involve sending samples to an external provider to assess the lab’s performance. Participation in EQA is a strong indicator of a lab’s commitment to quality. Ask which EQA programs the lab participates in and how often they undergo these assessments.

4. Ask About Quality Management Systems

A robust quality management system (QMS) includes documented procedures, staff training, and continuous improvement processes. Ask the lab about their QMS and whether they follow international standards such as ISO 15189.

5. Review Sample Handling and Reporting Protocols

Inquire about how the lab handles samples, including chain of custody, labeling, and storage. Also ask about their reporting procedures, including how results are communicated and how they handle inconclusive or ambiguous results.

6. Consider the Laboratory’s Experience and Specialization

While not a formal accreditation, the experience of the laboratory in performing PGT can be relevant. Ask about the number of PGT cycles they have processed and their success rates, but remember that success rates are not standardized and should be interpreted with caution.

Questions to Ask Your Clinic

• Can you provide a copy of the laboratory’s current accreditation certificate?
• Which accrediting body issued the certificate, and what is its scope?
• Does the laboratory participate in external quality assessment programs? If so, which ones?
• What quality management standards does the laboratory follow?
• How are samples handled and tracked from biopsy to result?
• What is the laboratory’s experience with the specific type of PGT I need?

Next Steps: Your Verification Plan

1. Shortlist clinics that offer PGT and are transparent about their laboratory arrangements.
2. Contact each clinic and request the laboratory’s accreditation details.
3. Review the accreditation certificate and verify its validity with the accrediting body if possible.
4. Ask about EQA participation and quality management practices.
5. Consider scheduling a consultation to discuss your specific case and ask any remaining questions.

Verifying PGT lab accreditation is a key part of making an informed decision. Use this checklist to guide your conversations with clinics and laboratories in Thailand.

Frequently asked questions

What is the most recognized accreditation for PGT labs in Thailand?

There is no single 'most recognized' accreditation. International bodies like the College of American Pathologists (CAP) and Joint Commission International (JCI) are widely recognized, as are national accreditations from the Thai Bureau of Laboratory Quality Standards. The important thing is that the accreditation is current and covers the specific PGT services you need.

How can I verify a lab's accreditation is valid?

Ask the clinic for a copy of the accreditation certificate and note the accrediting body, issue date, and expiration date. You can also contact the accrediting body directly to confirm the lab's status, as many have online directories.

What is external quality assessment (EQA) and why does it matter?

EQA is a program where a laboratory receives unknown samples from an external provider and must analyze them correctly. Participation in EQA demonstrates that the lab's results are reliable and comparable to other labs. It is a key indicator of quality.

Does accreditation guarantee a successful pregnancy?

No. Accreditation indicates that a lab meets certain quality standards, but it does not guarantee a specific outcome. Many factors affect the success of PGT and IVF, including the patient's age, the quality of the embryos, and the expertise of the entire clinical team.
