The Cortisol Test measures the level of the hormone cortisol in blood, urine, or saliva to evaluate adrenal gland function and stress response.
Read moreCortisol is a steroid hormone produced by the adrenal glands that plays a vital role in regulating blood pressure, blood sugar levels, and the body's stress response. The Cortisol Test is requested to diagnose adrenal disorders such as Cushing’s syndrome (excess cortisol production) or Addison’s disease (low cortisol production). Samples may be collected at different times of the day, as cortisol levels vary throughout the day, typically measured in the morning and evening for comparison.
