Cortisol, PM

This test measures the level of cortisol, a hormone that helps your body manage stress and energy, in your blood during the afternoon or evening. It helps show whether your hormone levels follow a healthy daily pattern, as cortisol should naturally drop later in the day. This measurement is often used to screen for adrenal gland disorders, such as Cushing’s syndrome, where levels remain abnormally high at night. However, a single result cannot diagnose a specific disease or determine the exact cause of a hormone imbalance on its own.
