The 17-hydroxycorticosteroids (17-OHCS) test measures the levels of these steroids in urine, which are important markers of adrenal gland function. It's used to diagnose conditions like Cushing syndrome, where the body has excessive cortisol. A 24-hour urine sample is typically collected for the test. Here's a more detailed explanation: What it is: 17-OHCS are produced when the liver and body tissues break down cortisol, a steroid hormone. Why it's tested: The test helps determine if the body is producing too much cortisol, which can be a sign of Cushing syndrome. How it's performed: A 24-hour urine sample is collected, and the 17-OHCS levels are measured. Normal range: Normal levels vary slightly between males and females. High levels: Elevated 17-OHCS levels can indicate Cushing syndrome, stress, or other conditions. Conditions related to high levels: Cushing syndrome, depression, hydrocortisone therapy, malnutrition, obesity, pregnancy, high blood pressure, pituitary gland tumors, and physical and emotional stress.
