There are different types of cortisol tests that may be performed, including blood, saliva, and urine tests. The urine test is done over a period of 24 hours.

The cortisol urine test tends to be more comprehensive than the other types of cortisol tests. It measures the total amount of cortisol excreted into the urine over a 24-hour period. Blood tests or saliva tests, however, only measure cortisol levels at a particular time of day. Some people also find blood tests to be stressful, and since the body releases more cortisol during times of stress, the results may not be as precise. In some cases, your doctor may order both a cortisol urine test and another type of cortisol test to obtain more accurate results.
