This test measures cortisol levels in your saliva. Cortisol, a hormone produced by the adrenal glands, affects almost every organ and tissue in your body. Proper cortisol levels are important in helping the body respond to stress, fight infection, regulate blood sugar, maintain blood pressure, and regulate metabolism.

You must get a specimen collection kit from the lab to take this test. This allows you to make the sample collections where and when it is convenient for you, without having to return to the lab to collect each of the four samples. 

What is a Cortisol Saliva Test?

The Cortisol Saliva Test works by collecting 4 samples of saliva and measuring the amounts of cortisol in each sample. If your cortisol levels are too high or too low, it may mean you have an adrenal gland disorder. These disorders can be serious if not treated.

Why would my doctor order a Cortisol Saliva Test?

Your provider may order a saliva test for cortisol to diagnose certain adrenal and pituitary gland conditions, such as Cushing’s syndrome, Addison’s disease, and adrenocortical insufficiency or hypersecretion.

When should I order a Cortisol Saliva Test?

Your provider may wish to order a Cortisol Saliva Test if you’ve exhibited the following symptoms:  

• Abnormally high or low blood pressure
• Sudden weight gain or loss
• Purple abdominal streaks 
• Fatigue 
• Abdominal pain
• Dark patches on the skin. 

How do I read the results of the test?

Once you receive the results of your saliva test for cortisol, you will need to consult with your provider. Only a medical professional can advise you on the results of your cortisol levels and help you develop a treatment plan if necessary. 

Do my results change with age?

A Cortisol Saliva Test will show slight fluctuations over time. Changes in your sleep schedule may also make your cortisol levels fluctuate. However, significant changes in cortisol levels are often due to adrenal or pituitary gland issues. 

What should I expect at my appointment?

FAQs

What's the difference between a Cortisol Saliva Test and a Cortisol Blood Test? 

Cortisol saliva tests allow you to collect 4 samples of cortisol throughout the day, whereas blood tests only collect a single sample at one time. Since cortisol levels fluctuate throughout the day, the Cortisol Saliva Test is considered to be more accurate. 

Does alcohol consumption affect the Cortisol Saliva Test? 

Alcohol has been found to increase levels of cortisol, both while consuming alcohol, and while withdrawing from the effects of alcohol.
