When you are comparing fertility clinics in Thailand, laboratory quality is one of the most important factors you cannot see directly. You can read about success rates, but those numbers depend on many variables. A more reliable approach is to ask for specific evidence about the laboratory itself: who works there, what certifications it holds, and how it monitors quality. This guide explains what documents a clinic may be able to provide, how to read them without overinterpreting, and what to confirm in writing before you commit.
At a glance
- Laboratory evidence includes accreditation certificates, staff credentials, quality-control records, and details about testing performed on site versus sent elsewhere.
- Accreditation scope varies: a certificate may cover the whole hospital, only the IVF laboratory, or a specific type of testing.
- Ask for the current certificate, the exact name of the accredited entity, and the expiry date.
- No single document guarantees a successful outcome. Use evidence to compare transparency and process, not to predict your own result.
- Request written confirmation of who will perform each step of your laboratory work.
Why laboratory evidence matters for international patients
IVF and preimplantation genetic testing (PGT) involve delicate laboratory steps: embryo culture, biopsy, freezing, and genetic analysis. These steps happen behind the scenes, often in a different room or building from where you meet your doctor. For international patients, the challenge is greater because you may not be able to visit in person before treatment.
Laboratory evidence helps you understand whether a clinic has established systems for quality control, staff training, and equipment maintenance. It does not tell you your personal chance of success, but it can help you judge whether the clinic operates with transparency and consistency.
What documents and credentials can a clinic provide?
Clinics vary in what they share publicly and what they provide on request. Here are common categories of evidence you can ask about.
1. Accreditation certificates
Accreditation is a voluntary process where an independent organization reviews a facility against defined standards. In fertility care, you may encounter:
- JCI (Joint Commission International) – often hospital-wide, covering patient safety and clinical quality.
- RTAC (Reproductive Technology Accreditation Committee) – specific to fertility laboratories and services.
- ISO 9001 – a general quality management standard, not specific to IVF.
- ISO 15189 – a standard for medical laboratories, including genetic testing.
- CAP (College of American Pathologists) – laboratory accreditation, often for genetics or pathology.
- UK NEQAS – external quality assessment schemes for laboratory testing.
Each certificate has a scope. For example, a hospital may hold JCI accreditation, but that does not automatically mean its IVF laboratory is accredited by RTAC. Ask for the certificate itself and check which entity and which services are listed.
2. Staff credentials
Ask about the embryologists and geneticists who will handle your eggs, sperm, and embryos. You can request:
- Names and qualifications of the laboratory director and senior embryologists.
- Whether embryologists hold certifications such as ESHRE certification (as described by some clinics).
- Experience with your specific type of testing (for example, PGT-A, PGT-M, or PGT-SR).
Some clinics list these details on their websites; others provide them on request. If a clinic cannot name the person who will perform your testing, that is a point to clarify.
3. Quality-control and proficiency-testing records
Laboratories should participate in external quality assessment (EQA) or proficiency testing for the tests they offer. You can ask:
- Does the laboratory participate in EQA for embryo culture, semen analysis, and genetic testing?
- How often are internal audits performed?
- What are the laboratory’s key performance indicators (for example, embryo survival after thaw)?
Clinics may not publish these details, but they can often provide a summary or explain their process.
4. Equipment and technology documentation
Some clinics describe specific equipment, such as time-lapse incubators or witness systems. You can ask for:
- Brand and model of incubators and other critical equipment.
- Maintenance and calibration schedules.
- Whether the clinic uses an electronic witnessing system to track samples.
This information helps you understand the laboratory’s infrastructure, but it does not replace accreditation or staff expertise.
How to interpret laboratory evidence without overreaching
It is easy to see a certificate and assume it guarantees quality. Instead, treat evidence as a starting point for questions.
- Check the scope. A certificate for the hospital does not automatically cover the IVF laboratory. Ask for the specific laboratory’s accreditation.
- Check the date. Certificates expire. Request the current version and note the expiry date.
- Check the name. The accredited entity may be a parent company or a different legal name. Confirm it matches the clinic you are considering.
- Ask about limitations. No laboratory can guarantee a pregnancy. Accreditation means the laboratory meets certain process standards, not that every cycle will succeed.
- Compare like with like. If one clinic holds RTAC and another holds ISO 9001, these are different standards. Ask what each covers.
Questions to ask about lab standards
Use these questions when you contact a clinic. Request written answers so you can compare.
- Which accreditations does your IVF laboratory hold, and can you provide the current certificates?
- Who is the laboratory director, and what are their qualifications?
- Are your embryologists certified by a recognized body? If so, which one?
- Do you perform PGT in-house or send samples to an external laboratory? If external, which laboratory?
- What is your process for embryo biopsy and genetic testing?
- How do you monitor laboratory quality (for example, EQA, audits, KPIs)?
- What equipment do you use for embryo culture and freezing?
- Can you provide a sample laboratory report for a typical PGT case?
- How do you handle incidents or discrepancies in the laboratory?
- What are the costs for laboratory procedures, and what is included in the quoted price?

Next steps: a checklist for verifying laboratory evidence
- Request certificates. Ask for the current accreditation certificates for the IVF laboratory and genetics laboratory (if applicable). Check the scope, entity name, and expiry date.
- Ask for staff credentials. Request the names and qualifications of the laboratory director and embryologists who will handle your case.
- Clarify testing location. Confirm whether PGT is performed in-house or sent to an external laboratory. If external, ask for the name and accreditation of that laboratory.
- Request quality-control information. Ask about EQA participation, internal audits, and key performance indicators.
- Get a written quotation. Ensure the quotation lists all laboratory procedures, medications, testing, storage, and any exclusions.
- Ask about incident reporting. Understand how the clinic handles laboratory errors or discrepancies.
- Compare responses. Use the same questions for each clinic and compare their answers side by side.

Frequently asked questions
What is the difference between hospital accreditation and IVF laboratory accreditation?
Hospital accreditation, such as JCI, reviews the entire hospital's patient safety and quality systems. IVF laboratory accreditation, such as RTAC, focuses specifically on the embryology laboratory and assisted reproduction services. A hospital may hold JCI accreditation without its IVF laboratory being separately accredited. Always ask for the certificate that covers the laboratory performing your treatment.
How can I check if a clinic's PGT laboratory is certified?
Ask the clinic whether PGT is performed in-house or sent to an external laboratory. If in-house, request the laboratory's accreditation certificates (for example, ISO 15189, CAP, or UK NEQAS participation). If external, ask for the name of the external laboratory and its credentials. You can then verify those credentials directly with the accrediting body if needed.
Does a clinic's accreditation guarantee a successful pregnancy?
No. Accreditation indicates that a laboratory meets certain process and quality standards, but it does not predict individual outcomes. Many factors affect IVF success, including age, diagnosis, and treatment protocol. Use accreditation as one piece of information when comparing clinics, not as a guarantee.
What should I do if a clinic cannot provide laboratory accreditation documents?
If a clinic cannot provide specific laboratory accreditation documents, ask for other evidence of quality control, such as staff credentials, equipment maintenance records, or participation in external quality assessment schemes. If the clinic is unable to provide any verifiable laboratory evidence, you may want to consider other clinics that are more transparent.
How often do accreditation certificates need to be renewed?
Renewal periods vary by accrediting body. For example, JCI accreditation is typically renewed every three years, while ISO certifications may be renewed on a different cycle. Always ask for the current certificate and check the expiry date to ensure it is valid at the time of your treatment.
