The 17-Hydroxyprogesterone (17-OHP) Test measures the levels of 17-OHP, a hormone produced by the adrenal glands, in blood or urine. Abnormal levels can indicate congenital adrenal hyperplasia (CAH), adrenal gland disorders, or hormonal imbalances. This test helps healthcare providers assess adrenal function, diagnose endocrine disorders early, and guide treatment plans to maintain hormonal balance and overall health.
