What is the Cortisol Free 24 Hours Urine Test?

The Cortisol Free 24 Hours Urine Test measures the amount of unbound (free) cortisol eliminated in urine over an entire day. Unlike a single blood cortisol measurement, this test reflects overall cortisol production during a 24-hour period. It is widely used to help diagnose Cushing’s syndrome, assess adrenal gland disorders, and monitor patients receiving treatment for cortisol-related conditions.

Who should take this test?

Individuals with suspected Cushing’s syndrome.
Patients with unexplained weight gain, especially around the abdomen and face.
People with persistent high blood pressure or uncontrolled diabetes.
Individuals experiencing muscle weakness, easy bruising, or purple stretch marks.
Patients undergoing evaluation for adrenal gland disorders.
Doctor-recommended monitoring of cortisol-related conditions.

Preparation & Test Process

Sample Type

A complete 24-hour urine collection is required. Follow the laboratory instructions carefully to ensure accurate results.

Fasting

Fasting is generally not required.

Preparation

Inform your doctor about all medications, including corticosteroids, oral contraceptives, and other hormone therapies, as they may affect cortisol levels.

Important Note

Missing any urine during the 24-hour collection may lead to inaccurate results. Follow the collection instructions exactly as provided by the laboratory.

Understanding Your Results

High urinary free cortisol levels may suggest Cushing’s syndrome, adrenal tumors, pituitary disorders, or prolonged stress.

Low urinary free cortisol levels may be associated with Addison’s disease, adrenal insufficiency, or reduced cortisol production.

Results should always be interpreted together with your symptoms, physical examination, blood cortisol levels, ACTH testing, imaging studies, and other endocrine investigations.
