Anti-Müllerian Hormone Test Test
The AMH test measures the amount of anti-Müllerian hormone in your blood. It helps check ovarian reserve, predict response to fertility treatment, diagnose PCOS, monitor ovarian cancer, and evaluate testicular function in babies.
What this test measures
An anti-Müllerian hormone (AMH) test measures the amount of AMH in a blood sample. AMH is made by the testicles in males and the ovaries in females. Levels vary with sex and age.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Higher-than-normal results
A high level of AMH may mean you have more eggs available. If tested for PCOS, a high level may be a sign of the disease. Certain types of ovarian cancer can also cause high AMH levels.
Lower-than-normal results
A low level of AMH may mean your egg supply is shrinking and your time to get pregnant may be shorter. Low AMH may also mean you are getting close to menopause. In male babies, little or no AMH may mean the testicles are not working or missing.
Frequently asked questions
What is an AMH test used for?
AMH tests are mainly used with other tests to make decisions about treating female infertility. They can check ovarian reserve and predict how well you may respond to fertility medicine.
Can an AMH test tell me if I can get pregnant?
No. An AMH test can tell you the size of your ovarian reserve, but it cannot tell you about the health of your eggs or predict whether you will be able to get pregnant.
What does a high AMH level mean?
In general, a high level of AMH means you have more eggs available. It may also be a sign of PCOS or certain types of ovarian cancer.
What does a low AMH level mean?
A low level means your egg supply is shrinking and your time to get pregnant may be shorter. It may also mean you are getting close to menopause.
Can an AMH test diagnose PCOS?
An AMH test alone cannot diagnose PCOS. A high level of AMH is a sign that you may have the disease, but other tests are needed for diagnosis.
