What is the purpose of this test?
The Cortisol Blood Test, PM, measures the level of cortisol in your blood in the afternoon or evening. Cortisol is a hormone produced by the adrenal glands that helps regulate many body functions, including metabolism, immune response, and stress. This test specifically checks cortisol levels later in the day, as they naturally decrease from morning to evening.
Doctors use the Cortisol Blood Test, PM, to assess how well your adrenal glands are functioning and to diagnose conditions related to cortisol levels, such as Cushing's syndrome or Addison's disease. It can also help monitor treatment effectiveness in patients with these conditions. Additionally, this test may be used to investigate symptoms like chronic fatigue, weight gain or loss, and mood disorders, which can be linked to abnormal cortisol levels in the afternoon or evening. Understanding cortisol levels in the afternoon provides important insights into your overall hormonal balance and health.
