What Is Anti-Müllerian Hormone (AMH)?
AMH is a hormone produced primarily by the cells in the ovaries. It plays a role in the development of eggs (ova) and helps determine a person’s ovarian reserve—the number of eggs remaining in the ovaries. AMH is often measured to evaluate fertility, especially in women who are planning pregnancy or experiencing infertility.
Why Might You Need This Test?
Your healthcare provider may order an AMH test if you’re experiencing fertility issues, planning to undergo fertility treatments, or if you have symptoms that suggest hormonal imbalances affecting reproductive health. It can also be useful in monitoring ovarian health in certain medical conditions.
What Does the Test Involve?
A blood sample is taken from a vein in your arm. The sample is then sent to a lab for analysis. The test does not require fasting or special preparation, but always follow your provider’s instructions for best results.
How Is the Result Interpreted?
AMH levels can vary widely among individuals. While there are general reference ranges, they are not strictly standardized for everyone. Your results will be discussed with your healthcare provider to determine their clinical significance based on your age, medical history, and symptoms.
Reference range
Adult: 3.5-5.0 mmol/LN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
AMH levels can provide important clues about ovarian health. Lower AMH levels may indicate reduced ovarian reserve, which can affect fertility. Higher levels may suggest better egg quality or reserve. However, AMH alone is not a definitive test for fertility and should be considered alongside other factors, such as age, menstrual history, and medical history.
