Understanding the Cortisol Urine 24-Hour Test
What It Is: The Cortisol Urine 24-Hour Test, also known as the urinary free cortisol (UFC) test, measures the amount of cortisol excreted in your urine over a 24-hour period. Cortisol is a hormone produced by the adrenal glands in response to stress and plays a crucial role in regulating various bodily functions, including blood sugar levels, blood pressure, and immune response.
Why It's Done:
Diagnosing Hormonal Disorders:
The test helps identify abnormalities in cortisol levels, which can indicate conditions such as Cushing's syndrome (high cortisol levels) or Addison's disease (low cortisol levels).
It assists in diagnosing other medical disorders related to abnormal cortisol levels.
Monitoring Health:
This test is useful for individuals with symptoms suggestive of hormonal imbalances, such as unexplained weight gain or loss, fatigue, muscle weakness, and high blood pressure.
It helps evaluate the effectiveness of treatments and monitor the progression of the condition.
Understanding the Results:
High Cortisol Levels:
Elevated cortisol levels may indicate Cushing's syndrome, which can cause symptoms such as increased urination, increased thirst, weight gain, and muscle weakness2.
Low Cortisol Levels:
Low cortisol levels may suggest Addison's disease or secondary adrenal insufficiency, which can cause symptoms such as weight loss, fatigue, dizziness, and abdominal pain2.
Why Your Doctor Might Order This Test:
Symptoms of Hormonal Imbalances:
If you have symptoms such as unexplained weight gain or loss, fatigue, muscle weakness, or high blood pressure, this test can help diagnose the underlying cause.
Monitoring Treatment:
For patients undergoing treatment for hormonal disorders, this test helps monitor the effectiveness of the treatment.
Symptoms That Might Prompt This Test:
Unexplained weight gain or loss
Fatigue
Muscle weakness
High blood pressure

Lifestyle and Management:
Depending on your results, your healthcare provider might recommend further tests, treatments, or lifestyle changes to manage hormonal imbalances effectively.
Regular monitoring and follow-up are essential for successful treatment.
