Cortisol in 24-Hour Urine

If you suspect issues with your cortisol levels, you can have a cortisol in 24-hour urine test at IntroLab in Belgrade. This test accurately measures the concentration of this important hormone and provides insight into the functioning of your adrenal glands.

What is Cortisol?

Cortisol is a steroid hormone produced and secreted by the adrenal glands located above the kidneys. Known as the “stress hormone,” its production increases when the body experiences stress. Cortisol helps the body adapt to and manage stress, and it also plays crucial roles in other functions. It regulates metabolism, controls blood pressure, reduces inflammation, and manages the sleep-wake cycle.

Why Measure Cortisol in 24-Hour Urine?

Cortisol levels can fluctuate due to various reasons, and measuring these levels precisely is important. Elevated cortisol levels may indicate Cushing’s disease, while low levels may suggest Addison’s disease or hypopituitarism. The 24-hour urine cortisol test is also useful for diagnosing adrenal insufficiency and other endocrine disorders.

When is it Necessary to Perform the Test?

This test is recommended if you have symptoms suggesting a cortisol production disorder, such as:

• Fatigue
• Weakness
• Sudden weight loss
• Changes in blood pressure
• Excessive sweating
• Changes in menstrual cycles in women

How is Cortisol Measured in 24-Hour Urine?

The 24-hour urine cortisol test involves collecting all urine produced over a 24-hour period. The start and end times of the collection period must be accurately recorded. After the collection is complete, the sample is sent to the laboratory for analysis.

Specifics of the Test

The 24-hour urine cortisol test offers a comprehensive view of cortisol levels over an entire day, unlike blood or saliva tests that measure cortisol at a single point in time.

Types of Cortisol Tests

Besides the 24-hour urine cortisol test, other tests to assess cortisol levels include blood cortisol tests and saliva cortisol tests.
