The Anti-Müllerian Hormone (AMH) test measures the level of AMH in the blood, which is produced by cells in the ovaries. AMH is a key indicator of ovarian reserve, reflecting the number of remaining eggs and the overall health of the ovaries. This test is used to assess fertility potential, predict the onset of menopause, and evaluate conditions like polycystic ovary syndrome (PCOS). It is particularly useful in fertility treatments, helping to determine the best approach for in vitro fertilization (IVF). A blood sample is required for this test.
