Order Cortisol Levels Blood TestCortisol is a steroid hormone produced by the adrenal glands and released in a daily rhythm that peaks in the early morning and declines through the day. Because it influences carbohydrate, protein, and fat metabolism, its concentration is often measured when the adrenal or pituitary systems are being evaluated. A cortisol levels blood test reports the amount of cortisol circulating in the bloodstream at the time the sample is drawn.
About Cortisol Levels Blood Test in Addison
Understanding what cortisol does helps explain why the test is ordered.
Cortisol is synthesized in the adrenal cortex under the control of adrenocorticotropic hormone (ACTH), which is secreted by the pituitary gland. This chain of command means that abnormal cortisol results can point to a problem in the adrenal glands, the pituitary, or the regulatory feedback between them.
The hormone supports the body's response to stress and helps maintain blood glucose by promoting gluconeogenesis from stored fuels. It also modulates immune activity, blood pressure, and the sleep-wake cycle, so both persistently high and persistently low concentrations can produce wide-ranging effects.
Because cortisol secretion follows a diurnal pattern, the time of collection matters when interpreting a result. A single measurement is often considered alongside the collection time, the clinical picture, and sometimes additional tests such as ACTH or a dexamethasone suppression study before any conclusion is drawn.
