About Cortisol AM & PM Test | Cortisol Levels in Berkeley
Cortisol is a steroid hormone produced by the adrenal glands that influences nearly every organ system.
Cortisol is a steroid hormone produced by the adrenal glands that influences nearly every organ system. It plays a central role in the body's stress response, helps regulate blood sugar, blood pressure, and inflammation, and contributes to the sleep-wake cycle. Levels normally peak shortly after waking and decline gradually throughout the day.
The Cortisol AM & PM Test captures this fluctuation by collecting blood samples at two designated times. The morning draw typically occurs between 6 and 8 a.m., when cortisol should be at its highest, while the afternoon draw usually takes place between 4 and 6 p.m., when levels should be significantly lower. Comparing the two results provides a more complete picture than a single measurement.
This test is used to evaluate conditions that affect cortisol production, such as Cushing's syndrome (excess cortisol) or Addison's disease (insufficient cortisol). It may also be ordered for persistent fatigue, unexplained weight changes, high blood pressure, or other symptoms that suggest a hormonal imbalance. Results are interpreted alongside clinical findings and sometimes additional testing.
