Cortisol is a hormone made by the adrenal glands which has various functions in the body ranging from fighting infections to regulating blood sugar and metabolism and maintaining blood pressure. Testing cortisol levels is an evaluation of adrenal function where high and low levels may indicate the presence of certain diseases such as Addison’s Disease, Cushing’s Syndrome, or the presence of a tumor.

Cortisol can be tested alone or as part of adrenal gland function tests such as:

917- DEX Suppression Test – low dose
918- DEX Suppression Test – high dose
919- ACTH Stimulation Test
