Cortisol -Morning (7 to 9 AM)

This test measures the level of cortisol, a hormone produced by the adrenal glands that helps regulate stress response, metabolism, blood pressure, and immune function. Cortisol levels normally vary during the day and are usually highest in the morning. A healthcare professional may order this test to help evaluate symptoms or conditions related to adrenal gland or pituitary function, including suspected low or high cortisol production. Results are interpreted alongside symptoms, medical history, and other tests.
