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 how the body metabolizes carbohydrates, proteins, and fats, and it participates in the regulation of blood pressure, immune activity, and the sleep-wake cycle. Because cortisol follows a daily rhythm, a blood test that measures its concentration provides a point-in-time view of adrenal and pituitary function.
About Cortisol Levels Blood Test in Downey
The cortisol blood test quantifies the amount of cortisol circulating in the bloodstream at the moment of collection.
Cortisol secretion is not constant. Levels typically peak in the early morning and decline through the day, which is why the timing of a blood draw is recorded and interpreted alongside the result.
Clinicians order cortisol testing to evaluate suspected adrenal insufficiency, adrenal overproduction, or disruptions in the pituitary signals that control the adrenal glands. Symptoms such as persistent fatigue, unexplained weight change, low blood pressure, or unusual skin pigmentation may prompt the test.
A single cortisol value is rarely diagnostic on its own. It is usually considered with the collection time, the person's clinical history, and sometimes additional testing such as ACTH measurement, a dexamethasone suppression test, or salivary or urinary cortisol collection.
