Order Cortisol AM & PM Test | Cortisol LevelsCortisol is a steroid hormone produced by the adrenal glands and released in a daily rhythm that typically peaks shortly after waking and declines over the course of the day. Because that pattern carries as much information as any single number, a Cortisol AM & PM Test measures the hormone at two points in the day rather than once. The paired results give a fuller picture of how cortisol is fluctuating.
About Cortisol AM & PM Test | Cortisol Levels in Saratoga
A two-sample cortisol test is used to evaluate the body's daily cortisol rhythm.
Cortisol influences blood sugar, blood pressure, immune activity, and the body's response to stress. Its release is governed by the hypothalamic-pituitary-adrenal axis, a feedback loop in which the brain signals the adrenal glands and rising cortisol levels then suppress further signaling.
Under normal conditions, cortisol is highest in the morning and falls substantially by late afternoon or early evening. A morning and afternoon pair of specimens allows a laboratory and clinician to compare the two values and assess whether that expected decline is present.
Results are interpreted alongside symptoms, medications, and other laboratory findings. A single value outside a reference range does not by itself establish a diagnosis; the timing of the draw, sleep patterns, and recent illness or stress can all influence the measurement.
