Order Cortisol Levels Blood TestCortisol is a steroid hormone produced by the adrenal glands and released in response to signals from the pituitary gland. It influences carbohydrate, protein, and fat metabolism, helps regulate blood pressure and immune activity, and follows a daily rhythm that typically peaks in the early morning and declines through the day. A cortisol blood test measures the amount of this hormone circulating in the bloodstream at the moment the sample is drawn.
About Cortisol Levels Blood Test in Northbrook
What the cortisol blood test measures
The test quantifies total cortisol in the blood. Because cortisol is bound largely to carrier proteins and released in pulses, a single measurement reflects only the level at that specific time rather than a full picture of adrenal function.
Results are usually interpreted alongside the time of collection. Morning values are generally compared with morning reference ranges, and afternoon or evening values with ranges established for those times.
Clinicians may order the test when symptoms suggest either excessive cortisol production or insufficient production. It is often used together with other adrenal and pituitary tests to build a more complete assessment.
