CORTISOL
What does CORTISOL measure?
This test measures cortisol, a hormone produced by the adrenal glands that helps regulate stress response, metabolism, blood pressure, and immune function. It may be used to evaluate adrenal gland function or investigate possible hormone imbalance when considered alongside clinical findings and other test results. Cortisol levels can vary during the day and may be affected by stress, illness, and certain medicines, so interpretation depends on the timing and clinical context.
