cortisol

Cortisol is a glucocorticoid (steroid) hormone. It is released from the adrenal gland located above the kidneys in response to adrenocorticotropic hormone. The test measures the amount of cortisol in the blood. Abnormal cortisol levels indicate disorders of the adrenal gland, which can be serious if not diagnosed and treated on time. The test also helps evaluate the working/ efficacy status of the pituitary and adrenal glands.

Intravenous blood samples are collected for this test, and no specific preparation is required prior to sample collection.

You may feel a little stinging-like sensation when a needle is inserted while collecting the sample and may experience slight bruising; however, it subsides with time.

High cortisol levels in blood indicate Cushing's syndrome, while low levels indicate Addison’s disease or another type of adrenal disease. Other factors like infection, stress and pregnancy can affect cortisol levels. Some medicines and birth-control pills can also affect cortisol levels. If your cortisol results are not normal, it does not necessarily imply a medical condition. Talk to your health care provider for guidance.

The production of cortisol by the adrenal glands is regulated by the pituitary gland. It is a pea-shaped gland located at the base of the brain, sometimes called the ‘master gland’. The pituitary gland sends signals to the adrenal glands to produce the right amount of cortisol when you exercise or face any stressful situation.
