Cortisol is a major hormone present in our body and is an important contributor to a lot of bodily functions. When our body senses danger it releases the adrenocorticotropic hormone which further triggers the adrenal gland to secrete Cortisol. When that happens, the body is able to handle the problem at hand. The Cortisol level test is conducted to know whether there are unusual levels of this hormone in the body. Let us have a look at the Cortisol level test, its purpose, procedure, and the results.


Purpose of the Cortisol level test


A Cortisol level test is conducted to find if there are any abnormalities associated with the Adrenal gland. This includes diseases like Cushing’s syndrome and Addison’s disease. Both of these ailments happen when the Cortisol level is not within the desired range.


Symptoms of Cushing’s syndrome are:


  • Obesity
  • High Blood pressure
  • High blood sugar
  • The tendency of skin to get bruised
  • Muscle weakness
  • Irregularity in periods
  • Excess hair on the face

The procedure of the Cortisol test


Following are the steps involved when a Cortisol test is conducted:

    • The patient is made to sit in a chair and the vein in the arm is made visible by tying an elastic band.
    • The area around the vein is cleaned with rubbing alcohol.
    • Blood is extracted from the vein and transferred to a collecting tube.
    • Now the rubber band is removed from the hand and a bandage is applied to the area.


Results of the Cortisol level test


If the Cortisol level test is conducted between 6-8 AM, the levels of the hormone ideally should lie between 10-20 micrograms/deciliter. In case the levels are below the ideal ones, it signifies an ailment like Addison’s disease and Hypopituitarism. The use of certain drugs can also lower the cortisol levels but the doctor would be able to decide that.
