Cortisol -Evening (3 to 5 PM)

This test measures the level of cortisol, a hormone made by the adrenal glands, during the afternoon when levels normally decline. It may be used to help assess the body’s cortisol pattern and investigate symptoms or conditions linked with unusually high or low cortisol production. Healthcare professionals may order it as part of an evaluation for adrenal gland or pituitary gland disorders. Results are interpreted alongside symptoms, medical history, and other hormone tests.
