24 Hour Cortisol Urine Test

What Is A Cortisol Urine Test

Cortisol testing: How to collect a 24-hour urine sample

A cortisol urine test is also called a urinary free cortisol test or UFC test. It measures the amount of cortisol in your urine.

Cortisol is a hormone produced by the adrenal glands, which are located on top of the kidneys. Cortisol is often released in response to physical or emotional stress.

Cortisol functions by:

  • playing a role in mood regulation
  • playing a role in the metabolism of carbohydrates, fats, and proteins

Cortisol levels naturally rise and fall throughout the day. Theyre usually highest in the morning and lowest around midnight, but there are also variations that depend on the person.

When this 24-hour cycle is disrupted, however, the body can produce too much or too little cortisol. A cortisol test can be performed to determine the underlying cause of abnormal cortisol levels.

There are different types of cortisol tests that may be performed, including blood, saliva, and urine tests. The urine test is done over a period of 24 hours.

The cortisol urine test tends to be more comprehensive than the other types of cortisol tests. It measures the total amount of cortisol excreted into the urine over a 24-hour period.

Blood tests or saliva tests, however, only measure cortisol levels at a particular time of day. Some people also find blood tests to be stressful, and since the body releases more cortisol during times of stress, the results may not be as precise.

How Do I Get Ready For This Test

Ask your provider whether you need to restrict food, medicine, or activity before this test. Plan to be home for the 24 hours you do the test so you can store the urine sample properly. Be sure your provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don’t need a prescription and any illegal drugs you may use.

Cortisol Urine Test Urinary Free 24

A Cortisol Urine Test, Urinary Free is used in the diagnosis of Cushing syndrome requires evidence of cortisol hypersecretion. While serum cortisol levels fluctuate unpredictably and are strongly dependent on concurrent cortisol-binding globulin levels, a 24-hour urine specimen integrates the cortisol production for an entire day and is not affected by CBG. Urinary cortisol reflects the portion of serum-free cortisol filtered by the kidney, and correlates well with cortisol secretion rate.

Also Known As: Urinary Free Cortisol

Methodology:

Liquid chromatography/tandem mass spectrometry

Preparation:

You must take your lab order to the lab to obtain a proper specimen container before collection. No fasting required. Urinate at 8am and discard the specimen. Then collect all urine in 24-hour period, ending with final collection at 8am the next morning. Refrigerate the collected urine between all voidings or keep it in a cool place. Screw the lid on securely. Transport the specimen promptly to the laboratory. Container must be labeled with full name, date and time collection started, and date and time collection finished.

Test Results:

3-4 days. May take longer based on weather, holiday or lab delays.

  • On the second day of the urine collection:

  • Urinate into the container right after waking up. This will be the last sample.
  • Return the containers to the appropriate person as soon as possible.
  • If your infant needs to have a cortisol urine test, youll collect their urine in a special bag.

    The collection procedure is as follows:

  • Thoroughly wash the area around your babys urethra with soap and warm water.
  • After your baby has urinated, pour the urine sample in the bag into a collection container. Keep this container in a cool place.
  • Return the container to the appropriate person as soon as possible.
  • Collect urine samples over a 24-hour period. It will be necessary to check the bag often throughout the collection period.

    What Is This Test

    This test measures the level of the hormone cortisol in your urine. Hormones are chemical messengers that travel through your blood. Cortisol helps your body use proteins, fats and carbohydrates. It helps maintain blood pressure, control blood sugar levels, and regulate the immune system. It’s made and released by the adrenal glands, which sit atop the kidneys.

    Another hormone, adrenocorticotropic hormone , controls the release of cortisol. ACTH is made and released by the pituitary gland, which is at the base of your brain.

    Cortisol is released at different times during the day, so the best way to measure it is to collect all the urine you produce over a 24-hour period.

    What Is Cortisol And The Cortisol 24

    Cortisol is a glucocorticoid that is formed by the cortex of the adrenal glands. It is the primary hormone that is linked to stress and, is part of the fight-or-flight hormone. When you are doing something that your body is perceiving as a threat, your body releases into your brain a hormone called the adrenocorticotropic . This hormone triggers your adrenal glands and leads to the formation and release of both cortisol and adrenaline. Cortisol release is a very normal reaction of the body and, can be triggered by something as little as hearing a dog barking at you or a fire alarm in your apartment. This hormone production is how your body reacts to such a stimulus, which will give it more energy and strength.

    When your body is experiencing a fight or flight response, this means that adrenal glands are releasing their cortisol. As a result, unnecessary and detrimental functions of the body, that are not need it for this response, get suppressed. Responses normally involve having a rapid heart rate, dry mouth, upset stomach and diarrhea, and panic. In addition, during a fight or flight response, cortisol can also suppress any processes related to growth, your digestive system, your reproductive system, and make alterations to your immune system functions.

    What Should I Do After The Test

    A complete history and physical examination are critical in determining the pretest likelihood of a diagnosis of Cushing syndrome. Patients present with a wide range of clinical features ,2 and no single symptom is necessary to the diagnosis. A high positive likelihood ratio for Cushing syndrome has been found in the presence of ecchymoses , osteopenia or fracture , proximal muscle weakness and hypertension .3 Many of the signs and symptoms of Cushing syndrome are common in the general population. But if they occur at an unusual stage of life or if multiple and progressive features are present , then a diagnosis of Cushing syndrome should be considered.2
