What is the test?
The urine 24-hour free cortisol test measures the amount of cortisol, a hormone produced by the adrenal glands, excreted in the urine over a 24-hour period. This test provides valuable information about the body’s cortisol production and can aid in the diagnosis of conditions such as Cushing’s syndrome or adrenal gland disorders.
Test Procedure:
The patient collects all urine voided over a 24-hour period. The total volume of urine is measured, and a sample is sent to the laboratory for free cortisol measurement.
When to take the test:
When a healthcare provider suspects adrenal disorders, Cushing’s syndrome, or other conditions related to cortisol imbalance, they may order this 24-hour urine test.
Who should take the test:
Patients with symptoms suggestive of adrenal dysfunction, such as unexplained weight gain, high blood pressure, or changes in skin appearance, may require this 24-hour urinary free cortisol test for diagnosis and monitoring.
Precautions for exceptional cases (pregnancy, etc.):
Pregnant individuals can undergo this test if necessary, but healthcare providers should be informed about the pregnancy status for accurate interpretation of the results.

A: Yes, certain medications, including corticosteroids, can impact urinary free cortisol levels. Individuals should inform the healthcare provider about all medications being taken to interpret the urine 24-hour free cortisol test accurately.
Q2: What can abnormal urinary free cortisol levels indicate?
A: Abnormal urinary free cortisol levels can indicate conditions such as Cushing’s syndrome (excess cortisol production) or adrenal insufficiency (low cortisol production). Further tests and clinical evaluation are necessary to determine the underlying cause of abnormal urinary free cortisol levels.
Q3: Is the 24-hour urine collection method necessary for this test?
A: Yes, a 24-hour urine collection provides a more accurate measurement of free cortisol excretion, allowing healthcare providers to assess the body’s cortisol production over an extended period. This comprehensive data aids in the diagnosis and management of adrenal disorders.
