The 17-OH progesterone blood test measures the level of 17-hydroxyprogesterone in the bloodstream. 17-hydroxyprogesterone is a hormone that plays a crucial role in the production of other hormones, such as cortisol and sex hormones like testosterone and estrogen. This test is primarily used to evaluate the functioning of the adrenal glands and diagnose certain hormonal disorders.
Congenital Adrenal Hyperplasia (CAH) Diagnosis: The most common reason for performing this test is to diagnose or rule out congenital adrenal hyperplasia, a group of inherited disorders affecting the adrenal glands' ability to produce hormones. CAH can lead to abnormal development of sexual characteristics and other health issues.
Monitoring CAH Treatment: If a person has been diagnosed with CAH, the 17-OH progesterone test may be used to monitor the effectiveness of treatment and to adjust medication dosages.
Elevated levels of 17-OH progesterone may indicate the presence of CAH. Your doctor will interpret the results based on the reference range provided in our reports.
Fasting Requirements: In most cases, fasting is not required before the test. However, certain medications or medical conditions may interfere with the accuracy of the test results. It's important to inform your doctor about any medications, supplements, or health conditions you have before the test.
Timing: The test is often done in the morning when the levels of 17-hydroxyprogesterone are typically highest.
