17OH -Hydroxy Progesteron

You should get a 17-hydroxyprogesterone test if you have excess facial or body hair, severe acne, irregular periods, or infertility, especially when PCOS is suspected. It is also used for newborn screening for congenital adrenal hyperplasia (CAH), for babies with ambiguous genitalia, for early puberty in children, and for monitoring CAH treatment.

Fasting is usually not required for a 17-hydroxyprogesterone test, but give your sample early in the morning (around 7–9 AM), when levels are most reliable. Women should test during the early follicular phase (days 2–5 of the menstrual cycle). Inform your doctor about steroids, hormonal medicines, oral contraceptives, or pregnancy.
