CORTISOL

The cortisol test measures the level of cortisol, a steroid hormone produced by the adrenal glands, in the blood, urine, or saliva. Cortisol plays a crucial role in regulating metabolism, immune response, and stress. The test is used to diagnose and monitor conditions affecting cortisol levels, such as Cushing’s syndrome, Addison’s disease, and adrenal insufficiency. Elevated cortisol levels can indicate hypercortisolism, while low levels can suggest hypocortisolism. The cortisol test provides valuable information for assessing adrenal function, diagnosing underlying conditions, and guiding treatment decisions.
