A cortisol test measures the level of cortisol, a hormone produced by the adrenal glands, in your blood, urine, or saliva. Cortisol plays a vital role in various bodily functions, including metabolism, immune response, and stress response. The cortisol test is essential for diagnosing and managing disorders related to abnormal cortisol levels, such as Cushing’s syndrome and Addison’s disease. It helps evaluate how the body responds to stress, assesses the function of the adrenal and pituitary glands, and monitors the effectiveness of treatments for adrenal disorders. By understanding cortisol levels and their patterns, healthcare providers can better diagnose conditions, manage treatments, and improve overall health outcomes.
