About this test
The 17-Alpha-Hydroxyprogesterone (17-OHP) test measures the level of 17-OHP, a steroid precursor, in the blood. This measurement is crucial for diagnosing and monitoring congenital adrenal hyperplasia (CAH), a genetic disorder affecting adrenal hormone production. It is also used to evaluate individuals with suspected adrenal tumors or certain reproductive disorders like polycystic ovary syndrome (PCOS).
