Cortisol - Random

CORTISOL - RANDOM Test Purpose

The Random Cortisol Test measures the level of cortisol, a hormone produced by the adrenal glands, in a blood sample collected at any time of the day. Cortisol plays a vital role in regulating metabolism, blood pressure, immune function, and the body's response to physical and emotional stress. This test helps assess adrenal gland function and is commonly used to investigate symptoms caused by abnormal cortisol production.

A random cortisol test can aid in the diagnosis of conditions such as Cushing's syndrome (excess cortisol), Addison's disease (adrenal insufficiency), adrenal tumors, and other disorders affecting the hypothalamic-pituitary-adrenal (HPA) axis. It may also be recommended to monitor patients receiving corticosteroid therapy or to evaluate unexplained fatigue, weight changes, muscle weakness, low blood pressure, or persistent stress-related symptoms.

Since cortisol levels naturally fluctuate throughout the day, your doctor may interpret the results alongside your symptoms or recommend additional tests, such as morning cortisol, ACTH, or stimulation tests, for a more comprehensive evaluation.
