What Your Cortisol 24

The cortisol 24-hour urine test involves the collection of all passed urine within a period of 24 hours. When you take the sterilized container, you will need to discard the first urine sample after waking up then, you start collecting all the passed urine. During the second day, and within the 24-hour framework, you will need to urinate straight into the container after waking up. This will constitute the last sample.

The 24-hour cortisol urine test results will be in the normal ranges if the cortisol level is between 3.5 and 45 mg for the 24 hours sample. These results might vary slightly. If the levels are below 3.5 mg then, your cortisol levels are low. This indicates that the adrenal glands are not making enough cortisol and, it may indicate that you have a condition referred to as Addison disease . Of the cortisol levels are above 45 mg then, the levels are high and you may have Cushing syndrome that can be caused by many factors. These include having a tumor at the adrenal gland, having drank alcohol or caffeine, being under a lot of stress, or being depressed.

Why The Test Is Performed

Cortisol Urine Test

The test is done to check for increased or decreased cortisol production. Cortisol is a glucocorticoid hormone released from the adrenal gland in response to adrenocorticotropic hormone . This is a hormone released from the pituitary gland in the brain. Cortisol affects many different body systems. It plays a role in:

  • Metabolism of fats, carbohydrates, and protein
  • Nervous system function

and Addison disease , can lead to either too much or too little production of cortisol. Measuring urine cortisol level can help diagnose these conditions.

What Is Cortisol And The Cortisol 24

Phosphate In Urine Test | Phosphorus Urine Test |

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.

You will be instructed to stop taking such medications before the test.

What Does It Mean If Your Cortisol Free Urine Result Is Too Low

Suppressed cortisol values may also be observed in primary adrenal insufficiency and hypopituitarism. However, many normal individuals may also exhibit a very low 24-hour urinary cortisol excretion with considerable overlap with the values observed in pathological hypocorticalism. Therefore, without other tests, 24-hour urinary cortisol measurements cannot be relied upon for the diagnosis of hypocorticalism.

    • Keep the large container in the refrigerator.
    • Empty your bladder for the last time at or just before the end of the 24-hour period. Add this urine to the large container, and write down the time.

    What Abnormal Results Mean

    A higher than normal level may indicate:

    • Cushing disease , in which the pituitary gland makes too much ACTH because of excess growth of the pituitary gland or a tumor in the pituitary gland
    • Ectopic Cushing syndrome , in which a tumor outside the pituitary or adrenal glands makes too much ACTH
    • Severe depression
    • Tumor of the adrenal gland that is producing too much cortisol

    A lower than normal level may indicate:

    • Addison disease in which the adrenal glands do not produce enough cortisol
    • Hypopituitarism in which the pituitary gland does not signal the adrenal gland to produce enough cortisol
    • Suppression of normal pituitary or adrenal function by glucocorticoid medicines including pills, skin creams, eyedrops, inhalers, joint injections, chemotherapy

    Urinary Free Cortisol Measurement Most Accurate First

    Measuring 24-hour urinary free cortisol with liquid chromatography-mass spectrometry is the most accurate first-line diagnostic tool for diagnosing Cushings syndrome in adults, according to research published in The Journal of Clinical Endocrinology & Metabolism.

    Filippo Ceccato, MD, of the University Hospital of Padova, Italy, and colleagues analyzed data from 137 adults from 2012 to 2014 with clinical conditions suggestive of hypercortisolism. Within the cohort, 38 had a confirmed diagnosis of Cushings syndrome 99 did not have the diagnosis. In all patients, researchers measured 24-hour urinary free cortisol with liquid chromatography-tandem mass spectrometry , late-night salivary cortisol with a radio-immunometric method and serum cortisol with a 1-mg dexamethasone suppression test. Researchers performed all three tests on patients within 2 weeks to avoid fluctuations in cortisol production.

    Researchers found that using LC-MS/MS to measure urinary free cortisol revealed both a combined higher positive ratio and a lower negative likelihood ratio among the three first-line tests.

    After using a receiver operating characteristic -contrast analysis to compare the power of each test alone and combined with one another, the urinary free cortisol assay was at least as good as all the other possible combinations, according to researchers.
