About 17-Hydroxy Progesterone (17-OHP)
17-OHP is a hormone your doctor checks mainly to screen for congenital adrenal hyperplasia, a condition where the adrenal glands produce hormones in the wrong balance. It is often ordered for infants with ambiguous symptoms or women being investigated for irregular periods and excess hair growth.
The test is a straightforward blood draw with no fasting required. Because hormone levels can shift with the time of day and menstrual cycle, your doctor may specify when exactly to get the sample taken.
How to Prepare
- No fasting required.
- Morning sample is preferred, so try to visit us or book home collection early in the day.
