Description
Overview
The 17-Hydroxyprogesterone (17-OHP) test measures the level of 17-OHP hormone in the blood. This hormone is produced by the adrenal glands and is a crucial building block for producing other hormones like cortisol. This test is primarily used to screen for and diagnose Congenital Adrenal Hyperplasia (CAH), an inherited condition affecting the adrenal glands.
Why is this test performed?
Doctors prescribe this test to investigate specific hormonal imbalances:
- For Women: To distinguish between Polycystic Ovary Syndrome (PCOS) and adrenal disorders, especially if you have symptoms like unwanted facial hair (hirsutism), severe acne, or irregular menstrual cycles.
- For Infants: To screen for enzyme deficiencies that affect growth and development.
- For Men: To check for adrenal tumors or unexplained fertility issues.
Test Details
- Sample Type: Blood (Serum)
- Preparation: Fasting is not strictly required, but doctors often recommend collecting the sample in the morning (between 8 AM and 10 AM) when hormone levels are most stable. For women, the sample may need to be collected during a specific time of the menstrual cycle (follicular phase).
- Turnaround Time: Reports are typically available within 24 to 48 hours.
