Quick Facts
- Sample: Blood
- Fasting: No fasting is required. Avoid biotin over 5 mg for 8 hours before testing. Wait at least two weeks after fertility injections. AMH can be tested any day of the cycle.

What This Test Measures
This test measures the level of circulating Anti-Mullerian Hormone (AMH) in your blood. AMH is produced by granulosa cells in the ovary, where it helps regulate the formation of primary follicles by limiting excessive follicular recruitment driven by FSH. Because of this role in folliculogenesis, AMH is used by some healthcare providers as one marker related to ovarian function.
In males, AMH is produced by the Sertoli cells of the testes and remains elevated through early life before declining during puberty and adulthood. This test reports a single AMH value and does not measure FSH, estrogen, or any other hormone.
Benefits
- Reflects circulating AMH, a single hormone marker.
- May support evaluation of ovarian follicular activity.
- May assist in evaluating conditions like PCOS.
- May help evaluate premature ovarian failure.
- May assist in evaluation of testicular presence.
- Simple blood draw with no special preparation.
Who Is This Test For?
- Women whose provider wants to assess ovarian follicular activity.
- Women being evaluated for polycystic ovary syndrome (PCOS).
- Women being evaluated for premature ovarian failure.
- Individuals whose provider is assessing testicular presence.
- Anyone whose healthcare provider has recommended AMH testing.

FAQ
1. What is the purpose of this hormone test?
This test measures the amount of Anti-Mullerian Hormone (AMH) circulating in your blood. AMH is produced by granulosa cells in the ovary and by Sertoli cells in the testes. Your healthcare provider may use this single hormone measurement to help evaluate aspects of ovarian follicular activity, conditions such as PCOS or premature ovarian failure, or testicular presence. This test does not diagnose any condition on its own.
2. Who would benefit from this test?
This test may be appropriate for women whose provider wants to assess ovarian follicular activity, or who are being evaluated for conditions such as PCOS or premature ovarian failure. It may also be appropriate for individuals whose provider is evaluating testicular presence. Whether this test is right for you depends on your individual health history and your provider's guidance.
3. When should I order this test?
You may consider ordering this test if your healthcare provider wants to evaluate ovarian follicular activity or assess for conditions such as PCOS or premature ovarian failure. It may also be ordered when a provider is evaluating testicular presence. This test is intended to support, not replace, a full medical evaluation.
4. How does this test differ from other hormone tests?
This test measures only circulating AMH and does not measure FSH, estrogen, testosterone, or any other hormone. AMH is produced by granulosa cells in the ovary and by Sertoli cells in the testes, and it functions differently from stimulating hormones like FSH, which regulate follicular development rather than reflect it directly. This result should not be treated as interchangeable with results from other hormone tests.
5. Do I need to fast before this test?
No special preparation is required for this test.
6. How quickly will I get results?
Results are typically available in 11 business days. Results may take longer based on weather, holiday, or lab delays.
7. How do I interpret the results?
The meaning of your AMH result depends on factors such as your sex, age, medical history, and the reason your provider ordered the test. AMH results are often reviewed alongside other clinical information and, in some cases, other hormone measurements. A single abnormal result does not automatically confirm a hormonal condition, and a single normal result does not rule one out. Discuss your results with a qualified healthcare provider for full interpretation.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
8. What should I do if my results are abnormal?
If your AMH result falls outside the expected range, review it with a qualified healthcare provider. Your provider can help determine whether additional evaluation or testing is appropriate based on your individual health history. This test result does not provide a complete clinical conclusion on its own.
9. How often should I get tested?
There is no fixed testing schedule for AMH. How often you should be tested depends on your individual circumstances and should be decided as directed by your healthcare provider.
Pre-test preparation
No fasting is required. Avoid high-dose biotin supplements (over 5 mg) for 8 hours before testing. Wait at least two weeks after fertility injections before testing. AMH can be tested any day of the menstrual cycle; for a baseline result, women taking combined oral contraceptives may consider stopping them for at least two months.
