The cortisol test is a simple test ordered by your physician to measure the level of cortisol in the blood, urine or saliva. Cortisol is a hormone that is responsible for the response to stress and threat. It also plays a major role in various body functions such as fighting against infection and regulating blood sugar and metabolism.
The cortisol blood test is the most common way to measure the production of cortisol hormone. The disorders caused by high or low cortisol levels can lead to serious health issues if not treated. So, we highly recommend you to get tested for cortisol levels if you experience any of the symptoms that are caused by abnormal cortisol levels.
The article below covers all the significant topics related to cortisol test like the cortisol test cost, normal cortisol levels, procedure, cortisol saliva home test kit, preparation, risks and how to get tested for a cortisol test.

What is cortisol?
Cortisol is a steroid hormone that is produced by the adrenal glands. There are two adrenal glands that are small and located on the top of each kidney. Cortisol is the main hormone responsible for the response to stress and threat. So, it is also known as the “stress hormone”. Whenever you experience something that your body perceives as a threat, your brain releases a hormone called adrenocorticotropic hormone (ACTH). This hormone triggers the adrenal gland to release cortisol.
In addition to responding to stress, cortisol hormone is also responsible for various other body functions like fighting against infection, maintaining blood pressure, regulating the blood sugar levels, and regulating the metabolism.
Why is a cortisol test done?
The cortisol test is done to measure the levels of cortisol hormone. This test helps to diagnose the disorders in the adrenal glands and as a way to assess the functioning of the adrenal glands and the pituitary gland. The disorders in the adrenal glands include Cushing’s syndrome (a condition caused by high cortisol levels) and Addison’s disease (a condition caused by low cortisol levels).
Your physician will order a cortisol test if you experience the following symptoms that are caused by high and low cortisol levels.
Symptoms of high cortisol levels
- Obesity (especially in the trunk)
- High blood pressure
- High blood sugar
- Muscle weakness
- Fragile skin
- Purple stretch marks on the abdomen
- Osteoporosis (low bone density)
Symptoms of low cortisol levels
- Weight loss
- Muscle weakness
- Pain in the abdomen
- Dark patches of skin
- Low blood pressure
- Loss of body hair
- Loss of consciousness
- Sudden and severe pain in the abdomen, legs, or lower back
- Severe vomiting and diarrhea
Normal levels of cortisol
Generally, the cortisol levels are high after waking and low at bedtime. The normal cortisol levels might vary between the labs. However, the standard range of cortisol levels in a blood sample taken between 6 a.m. and 8 a.m. is between 6 and 23 mcg/dl (micrograms per deciliter).
How is the cortisol test done?
1. Cortisol blood test
It takes less than 5 to 10 minutes to perform this test.
2. Cortisol saliva home test kit
Is there any preparation required before the test?
There is no special preparation required for the cortisol blood test or saliva test. There is no constraint on the diet. But, your physician may ask you to stop certain medications that contain estrogen and androgen, and synthetic glucocorticoids such as prednisone, and phenytoin. Because these drugs and medications can influence the cortisol levels and result in an inaccurate diagnosis.
Are there any risks in the test?
There are no possible risks or complications in taking the cortisol saliva test. When the blood sample is drawn, you might feel dizziness, slight pain, bruise or redness in the injected area for a very little period. If you have any abnormal bleeding in the injected area, inform your physician immediately.
What does the test result mean?
If the cortisol levels are higher than normal, it indicates the possibility of Cushing’s syndrome that might be caused by a tumor in the pituitary gland or adrenal gland or in the other part of the body that is involved in producing cortisol.
If the cortisol levels are lower than normal, it indicates the possibility of Addison’s disease or hypopituitarism ( a condition in which the pituitary gland fails to function properly).
How to treat high and low cortisol levels?
Your physician will prescribe some medications and supplements to increase or lower the cortisol levels. Naturally, a proper combination of diet and physical exercise, and a healthy lifestyle can also help to maintain the normal cortisol levels.
The cortisol test can be done in any of the following locations across the U.S. either by visiting the nearest lab or getting tested at home using the saliva test kit. To know the cortisol test cost, refer to the first section of the article.
