What Is a Cortisol Levels Test?
The cortisol levels test measures the amount of cortisol in your body. Cortisol is a hormone made by your adrenal glands. It helps control stress, blood sugar, and blood pressure. Doctors use the cortisol levels test to check if your body makes the right amount of this hormone. Often, this test is called a cortisol blood test, but it can also use urine or saliva samples.
Why Is the Cortisol Levels Test Important?
Cortisol plays a big role in your health. For example, it helps your body respond to stress. It also keeps your blood sugar and blood pressure in balance. If your cortisol levels are too high or too low, it can cause health problems. Therefore, the cortisol levels test helps doctors find out if your adrenal glands are working well.
Symptoms and Conditions That May Require Testing
Sometimes, your doctor may suggest a cortisol levels test if you have certain symptoms. These symptoms can point to problems with your adrenal glands. For instance, you may need testing if you have:

Understanding Test Results
After your test, your doctor will explain the results. Normal cortisol levels depend on the time of day and the type of test. For example, blood cortisol is usually highest in the morning and lowest at night. The typical morning cortisol test normal range is about 6 to 23 micrograms per deciliter (mcg/dL). However, these numbers can vary by lab.
If your results are outside the normal range, your doctor will look at your symptoms and other tests. Sometimes, a single abnormal result may not mean you have a problem.
Causes of Abnormal Cortisol Levels
Many things can cause high or low cortisol levels. For instance, high cortisol can be due to:

Sometimes, you may need to see a hormone specialist, called an endocrinologist. Your doctor will guide you on the best next steps based on your health and symptoms.
