The 17-Hydroxy Corticosteroids blood test from Walk-In Lab measures levels of 17-OHCS, an inactive product formed when the liver and other body tissues break down the steroid hormone, cortisol. 17-OHCS is an indirect measurement of proper pituitary, or adrenal gland function.
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.
A higher than normal level of 17-OHCS may indicate:
- A type of Cushing syndrome caused by a tumor in the adrenal gland that produces cortisol
- Hydrocortisone therapy
- Severe high blood pressure
- Severe physical or emotional stress
- Tumor in the pituitary gland or elsewhere in the body that releases a hormone called adrenocorticotropic hormone (ACTH)
A lower than normal level of 17-OHCS may indicate:
- Adrenal glands are not producing enough of their hormones
- Pituitary gland is not producing enough of its hormones
- Hereditary enzyme deficiency
- Previous surgery to remove the adrenal gland
