Cortisol – AM/PM Test

The Cortisol – AM/PM Test measures cortisol at designated morning and evening times to provide information about the body’s daily cortisol pattern. Cortisol is an important hormone involved in the body’s response to stress and several normal metabolic processes. Levels naturally change throughout the day, so collection timing is important when interpreting results. Factors such as medications, sleep, stress, and illness can also influence cortisol measurements. This test may be used as part of a broader evaluation when hormonal concerns are being investigated. Results should be interpreted by a healthcare professional alongside symptoms, medical history, and other relevant findings.
