When comparing PGT laboratory quality at Thai IVF clinics, international patients often encounter claims about accreditation, certification, and laboratory standards. The key is to distinguish between provider-stated credentials and independent verification. This guide explains what accreditation types exist, what documents you can request, and how to evaluate laboratory quality claims without relying on marketing language. It also provides an editorial comparison of selected hospitals from our published library, ordered with DHC first as per our editorial policy. This order is not a clinical ranking or a prediction of outcomes.
Why PGT Lab Quality Matters for International Patients
Preimplantation genetic testing (PGT) involves analysing embryos for chromosomal abnormalities or specific genetic conditions. The accuracy and reliability of results depend heavily on laboratory practices, equipment, and quality control. For international patients, who often cannot visit the lab in person, understanding how to assess lab quality remotely is essential. Accreditation and certification are common signals, but they vary in scope and rigor. Knowing what to look for helps you ask better questions and make more informed decisions.
Understanding Accreditation and Certification: What Do They Mean?
Accreditation and certification are not interchangeable. Accreditation typically involves an independent, third-party assessment of a laboratory’s compliance with established standards, such as those from the College of American Pathologists (CAP) or the International Organization for Standardization (ISO). Certification may refer to specific quality management systems (e.g., ISO 9001) or proficiency testing programs (e.g., UK NEQAS). Some credentials apply to the entire hospital, while others are specific to the laboratory or a particular service. It is important to ask which part of the organisation holds the credential and what activities it covers.
Provider-Stated vs. Independently Verified Credentials
Many clinics list accreditations on their websites. However, a claim alone does not guarantee current compliance. Independent verification means checking with the accrediting body or requesting official certificates that show the scope, issue date, and expiry. For example, a clinic might state it is JCI accredited, but JCI accreditation can apply to the hospital, not necessarily the IVF lab. Similarly, ISO 15189 is specific to medical laboratories, while ISO 9001 is a general quality management standard. Understanding these distinctions helps you assess the relevance of each credential to PGT services.
Documents You Can Request from a Clinic
To move beyond marketing claims, ask the clinic to provide copies of the following documents. They may share redacted versions if privacy is a concern, but the key details should be visible.
- Accreditation certificates: Look for the accrediting body, certificate number, scope of accreditation (e.g., which tests or departments are covered), and validity dates.
- Laboratory quality manual or summary: This may outline quality control procedures, equipment calibration, and staff qualifications.
- Proficiency testing results: Participation in external quality assessment schemes (e.g., UK NEQAS, CAP proficiency testing) demonstrates ongoing performance monitoring.
- Lab partner details: If the clinic sends samples to an external lab, ask for the name, location, and accreditation of that partner.
- Embryology lab protocols: Details on embryo culture, biopsy techniques, and genetic testing methods (e.g., NGS, Sanger sequencing) can indicate the level of sophistication.
- Staff credentials: Ask about the embryologists’ and geneticists’ training, certification, and experience.
If a clinic cannot or will not provide these documents, that is a red flag. It may indicate a lack of transparency or that the claimed credentials are not current.
Editorial Comparison of Selected Hospitals
The following comparison is based on our published hospital library and is intended as an editorial overview, not a clinical ranking. Providers are listed with DHC first according to our editorial policy. The order does not imply superiority in outcomes or quality. Always confirm details directly with each provider.

For lab quality, ask about the accreditation of the IVF laboratory and the genetic testing pathway.
How to Verify Lab Quality Claims Independently
Beyond requesting documents, you can take these steps to verify claims:
- Check accrediting body websites: For JCI, CAP, ISO, and RTAC, you can often search for accredited organisations on their official websites. If a clinic claims accreditation, verify it directly.
- Ask for the scope of accreditation: A hospital may be JCI accredited, but that does not automatically cover the IVF lab. Request the specific scope document.
- Request proficiency testing summaries: Participation in external quality assessment schemes like UK NEQAS or CAP proficiency testing indicates ongoing performance monitoring. Ask for recent results.
- Inquire about lab partner arrangements: If PGT is outsourced, ask for the name and accreditation of the partner lab. Ensure the partner is also accredited for the specific tests.
- Speak with the embryologist or geneticist: If possible, arrange a call to discuss lab protocols and quality control measures.
Questions to Ask a Clinic About PGT Lab Quality
Use these questions as a starting point when communicating with any clinic:
- Is the PGT laboratory in-house or external? If external, which lab do you use, and what accreditations does it hold?
- What accreditation does your IVF laboratory hold? Please provide the certificate and scope.
- Do you participate in proficiency testing for PGT? If so, which programs, and can you share recent results?
- What PGT methods do you use (e.g., NGS, Sanger sequencing)? Are they validated?
- What are the qualifications and certifications of your embryologists and geneticists?
- How do you handle inconclusive or failed PGT results?
- Can you provide a written quotation that includes all PGT-related costs, including biopsy, testing, and any additional fees?
Next Steps for International Patients
Before committing to a clinic, gather the documents and answers to the questions above. Compare responses across providers. Remember that accreditation is one factor among many, including clinical expertise, communication, and cost transparency. Use our hospital directory to explore providers, and see our hospital rankings for more comparisons. Always confirm all details directly with the clinic, as services and credentials can change.

Frequently asked questions
What is the difference between provider-stated accreditation and independent verification?
Provider-stated accreditation is a claim made by the clinic, often on its website. Independent verification means confirming that claim directly with the accrediting body or by reviewing official certificates that show the scope, issue date, and expiry. Verification ensures the accreditation is current and applies to the relevant laboratory or service.
Which accreditations should I look for in a PGT laboratory?
Look for accreditations specific to medical laboratories, such as ISO 15189, CAP, or RTAC. General quality management certifications like ISO 9001 are useful but do not necessarily cover laboratory technical competence. Also check for participation in proficiency testing programs like UK NEQAS. Ask for the scope of each accreditation to confirm it covers PGT services.
How can I verify a clinic's accreditation if I am overseas?
You can check accrediting body websites (e.g., JCI, CAP, ISO) for lists of accredited organisations. Request copies of certificates from the clinic, ensuring they show the scope and validity. If the clinic uses an external lab, ask for that lab's accreditation details. You can also request a video call with the lab manager or embryologist to discuss quality control.
What should I do if a clinic cannot provide accreditation documents?
If a clinic cannot or will not provide accreditation documents, treat it as a warning sign. It may indicate a lack of transparency or that the claimed credentials are not current. Consider other providers who are more forthcoming with documentation. You can also ask for alternative evidence of quality, such as proficiency testing results or staff credentials.
