The Prolactin test helps diagnose and manage conditions related to pituitary gland function and reproductive health. Elevated prolactin levels can cause symptoms such as unexplained milk production, menstrual irregularities, and fertility problems. In men, high prolactin may lead to decreased libido and erectile dysfunction. Low prolactin levels may suggest pituitary gland issues. This test is essential for diagnosing prolactinomas, evaluating pituitary disorders, and managing reproductive and endocrine health.
