Order Cortisol AM & PM Test | Cortisol LevelsCortisol is a steroid hormone produced by the adrenal glands and released in a daily rhythm, typically peaking shortly after waking and declining through the day. Because that pattern matters as much as any single value, a Cortisol AM & PM test measures the hormone at two points in the day rather than once.
About Cortisol AM & PM Test | Cortisol Levels in St. Charles
A two-point cortisol measurement gives a fuller picture of adrenal output than a single draw.
Cortisol influences blood sugar, blood pressure, immune activity, and the body's response to stress. Its release follows a circadian pattern, so a morning specimen and an afternoon specimen are collected to show how levels rise and fall across the day.
Clinicians order paired cortisol testing when they want to evaluate the rhythm itself, not just whether a single result sits inside a reference interval. Comparing the two draws can reveal a flattened curve, an unusually high or low value, or a pattern that warrants further endocrine evaluation.
Results are interpreted alongside the collection times, the reference ranges used by the performing laboratory, and the individual's symptoms and history. A single abnormal value does not by itself establish a diagnosis; it is one piece of a broader clinical assessment.
