This test measures the levels of Anti-Müllerian Hormone (AMH), which plays a key role in assessing fertility potential, ovarian reserve, and ovarian aging. It is also useful in predicting the onset of menopause and diagnosing conditions like Polycystic Ovary Syndrome (PCOS). AMH levels remain relatively stable throughout the menstrual cycle and gradually decrease with age, making it an important marker for evaluating a woman’s reproductive health.
