Why the Test is Performed
17-hydroxycorticosteroid (17-OHCS) is a product formed when the liver and other body tissues break down the steroid hormone, cortisol.
This test can help determine if the body is producing too much of the hormone, cortisol. The test may be used to diagnose Cushing syndrome . This is a disorder that occurs when the body has a high level of cortisol.

Normal Results
Normal values:
- Male: 4 to 14 mg per 24 hours
- Female: 2 to 12 mg per 24 hours
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.
