At a glance
A practical checklist of common fertility tests you may be asked to complete before an IVF consultation in Thailand, plus how to organise records and what to confirm with your treating clinic.
Preparing for a first IVF consultation in Thailand usually starts with gathering information about your fertility health. Clinics commonly ask for a set of diagnostic tests before or during your first visit, but the exact list depends on your age, medical history, previous treatments and the clinic’s own protocols. This guide explains the categories of tests that may be requested, why they are done, and how to organise your records so your consultation is as productive as possible. It does not interpret results or recommend treatment. Always confirm the specific tests, timing and documentation requirements with the clinic you plan to attend.
At a glance
- Most fertility workups include hormone blood tests, an ultrasound scan, and a semen analysis for the male partner.
- Some tests are cycle-dependent, meaning they must be done on a specific day of your menstrual cycle.
- Bring copies of previous test results, imaging and treatment records in English where possible.
- Ask your clinic which tests they require, whether they accept results from your home country, and how long results remain valid.
- Travel timing may depend on when tests can be done and when results are reviewed.
Why diagnostic tests are requested before IVF
Before recommending any treatment, a clinic needs a baseline picture of your reproductive health. Tests help identify factors that may affect how you respond to ovarian stimulation, whether there are anatomical issues, or whether a male factor is present. They also help the clinical team plan a safe and appropriate approach. However, no single test can predict IVF success with certainty, and results are interpreted alongside your history and other findings. Your treating clinician is the only person who can explain what your results mean for you.
Common diagnostic tests that may be requested
The following tests are frequently part of a fertility workup. Your clinic may ask for all, some, or additional tests depending on your situation.
Ovarian reserve testing
Ovarian reserve tests estimate the number of eggs remaining in the ovaries. They do not measure egg quality or guarantee pregnancy. Common tests include:
- Anti-Müllerian hormone (AMH) blood test – can be done on most days of the cycle.
- Antral follicle count (AFC) – a transvaginal ultrasound scan, usually performed early in the menstrual cycle.
- Follicle-stimulating hormone (FSH) and estradiol – blood tests typically done on day 2–4 of your cycle.
These tests help estimate how you might respond to fertility medications, but they are not a definitive measure of fertility potential.
Hormone and ovulation tests
Other hormone tests may be requested to check ovulation, thyroid function, or other endocrine factors. Examples include:
- Thyroid-stimulating hormone (TSH)
- Prolactin
- Luteinising hormone (LH)
- Progesterone (often measured in the luteal phase to confirm ovulation)
Your clinic will specify the correct day of your cycle for each test.
Ultrasound and imaging
A transvaginal ultrasound is commonly used to assess the uterus, ovaries and endometrial lining. It may be done at different points in your cycle depending on what the doctor wants to evaluate. Other imaging, such as a hysterosalpingogram (HSG) or saline infusion sonohysterography (SIS), may be requested if there is a concern about the uterine cavity or fallopian tubes.
Semen analysis
If you have a male partner, a semen analysis is usually part of the initial workup. It assesses sperm count, motility and morphology. The clinic will provide instructions on how to collect the sample, including any required abstinence period. Results can vary, so a repeat test may be requested.
Infectious disease screening
Many clinics require screening for infectious diseases such as HIV, hepatitis B and C, and syphilis for both partners before proceeding with IVF. This is a standard safety measure and may also be required by law or laboratory regulations. Your clinic will tell you which tests are mandatory and whether they accept results from your home country.
Genetic and other tests
Depending on your history, your clinic may recommend genetic carrier screening, karyotyping, or other specialised tests. These are not routine for everyone and will be discussed based on your individual circumstances.
How to prepare your medical records
Organising your records in advance can save time and help your clinic understand your history quickly. Consider preparing:
- A summary of your fertility journey, including any previous treatments, medications, and outcomes.
- Copies of all previous test results, including blood tests, ultrasounds, and semen analyses.
- Any imaging reports (e.g., HSG, MRI) and, if possible, the images themselves.
- Records of any surgeries or medical procedures related to your reproductive health.
- A list of current medications, including doses and frequency.
- Vaccination records, if available.
If your records are not in English, ask your clinic whether they require a certified translation. Some clinics may accept digital copies in advance, while others may want to see originals. Confirm their preference.
Questions to ask your clinic before testing
Every clinic has its own requirements. Asking these questions early can help you plan:
- Which diagnostic tests do you require before a first consultation or before starting IVF?
- Do you accept test results from my home country, and if so, how recent must they be?
- Are any tests cycle-dependent, and how should I time them?
- Do you need the original reports or are digital copies sufficient?
- Will I need to repeat any tests in Thailand?
- What are the estimated costs for the tests you require?
- How long does it take to receive results, and when will they be reviewed?
- Can I complete some tests locally before travelling?
Planning your travel and appointments
Diagnostic testing can influence your travel timeline. Some tests must be done on specific days of your menstrual cycle, and results may take days or weeks to process. If you plan to travel to Thailand for your consultation, ask your clinic how to coordinate testing so that your visit is efficient. In some cases, you may be able to do initial tests at home and bring the results. In others, the clinic may prefer to perform tests themselves. There is no single timeline that fits everyone; your clinic can advise based on your individual situation.
Next steps
- Contact your chosen clinic and ask for their pre-IVF testing checklist.
- Gather your existing medical records and test results.
- Clarify which tests can be done locally and which must be done in Thailand.
- Ask about cycle timing and how to schedule tests around your travel.
- Confirm costs, translation requirements, and how results will be shared.
- Keep a folder (digital or physical) with all your records to bring to your appointment.

Frequently asked questions
Can I do fertility tests in my home country before travelling to Thailand?
Many clinics accept test results from other countries, but policies vary. Some may require tests to be repeated in Thailand, especially if they need to be done at a specific point in your cycle or if the clinic prefers its own laboratory. Ask your chosen clinic which tests they will accept and how recent the results must be.
How long do fertility test results remain valid?
Validity periods differ by test and by clinic. Some hormone tests may be considered current for a few months, while infectious disease screening may have a shorter or longer window. Your clinic will tell you how long they consider your results valid for their purposes.
Do I need to bring original documents or are digital copies enough?
Requirements vary. Some clinics accept digital copies for initial review but may ask for originals or certified translations later. It is best to ask your clinic directly and prepare both if possible.
What if my test results are outside the normal range?
Only your treating clinician can interpret your results in the context of your overall health and history. Do not try to interpret them yourself. Share all results with your clinic and ask for an explanation during your consultation.
Are there any tests that must be done on a specific day of my cycle?
Yes, some tests such as FSH, estradiol, and antral follicle count are typically done early in the menstrual cycle. Others, like progesterone, may be done later. Your clinic will give you specific timing instructions.
