What is this test?

The 17-Hydroxyprogesterone (17-OHP) test measures the amount of a hormone called 17-hydroxyprogesterone in your saliva. This hormone is produced by your adrenal glands, which are small glands located on top of your kidneys. 17-OHP is an important intermediate in the production of cortisol, a hormone that helps your body respond to stress, maintain blood pressure, and regulate metabolism.

Why is it performed?

This test is primarily used to: (1) Screen newborns for a genetic condition called congenital adrenal hyperplasia (CAH), which affects hormone production in the adrenal glands; (2) Monitor individuals already diagnosed with CAH to ensure treatment is working effectively; (3) Evaluate adrenal gland function in children and adults with symptoms of hormonal imbalances; (4) Help diagnose other adrenal disorders when needed.

How is the sample collected?

For a saliva test, you will be given a special collection kit. Typically, you will need to: (1) Rinse your mouth with water before collection; (2) Place a cotton swab or collection device in your mouth for 2-5 minutes to absorb saliva; (3) Place the swab in the provided container; (4) Follow specific timing instructions, as some tests require collection at certain times of day (often morning). The sample is then sent to a laboratory for analysis.

How to prepare?

Preparation may include: avoiding eating, drinking (except water), smoking, or chewing gum for 30-60 minutes before collection; not brushing teeth or using mouthwash before the test; informing your doctor about any medications you are taking, as certain drugs can affect results; following any specific instructions provided by your healthcare provider or the testing laboratory.
