Cortisol, AM & PM Test

A cortisol AM & PM test is a blood test that measures the levels of cortisol in the body at different times of the day. Cortisol is a hormone that is released in response to stress and helps regulate metabolism, immune function, and blood pressure.

In the morning, cortisol levels are typically higher as part of the body's natural circadian rhythm. This rise in cortisol helps wake us up and gives us energy to start the day. As the day goes on, cortisol levels naturally decrease.

By measuring cortisol levels in the morning and evening, healthcare providers can assess if the body is producing the right amount of cortisol at the right times. This test can be helpful in diagnosing conditions such as adrenal insufficiency or Cushing's syndrome, which are both related to abnormalities in cortisol production.

It is important to follow any specific instructions from your healthcare provider before taking a cortisol AM & PM test, such as fasting before the test or avoiding certain medications. Your provider will also discuss the results with you and recommend any necessary follow-up or treatment.
