Meet Cortisol, the Hormone You Can't Ignore

6. Diagnosis of cortisol imbalances

There are multiple ways to test for cortisol imbalances. Blood tests are effective, but they have to be done by a qualified healthcare provider. Blood samples are usually taken twice a day, once in the morning when levels are high and again in the later afternoon when they are lower.

Other options include urine tests and a saliva test. A cortisol urine test typically requires a 24-hour urine sample. The person collects their urine in a special bottle at home for 24 hours. In some cases, a cortisol urine test can be done with a single sample of urine collected in the morning. A cortisol saliva test can also be done at home. These tests are typically done at night before going to bed when cortisol levels are lower.

When a cortisol imbalance is detected, additional testing may be needed to determine the source of the imbalance. For example, CT scans and MRIs can detect tumors in the adrenal glands or pituitary glands. If you think you are displaying signs of a cortisol imbalance, talk to your doctor.
