Cortisol is the body's primary stress hormone, produced by the adrenal glands. It follows a natural daily rhythm — highest in the morning and lowest at night. Abnormal cortisol levels can indicate conditions such as Cushing's syndrome (excess cortisol), Addison's disease (cortisol deficiency), adrenal insufficiency, or chronic stress. This test measures total serum cortisol and is useful for evaluating adrenal function, fatigue, weight changes, and stress-related symptoms. For the most accurate results, morning collection is preferred.
