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 handles 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 measures the amount circulating at the moment the sample is drawn, and the result is interpreted alongside the time of collection and the clinical context.
About Cortisol Levels Blood Test in Fontana
The cortisol blood test quantifies the concentration of cortisol in serum or plasma.
Cortisol secretion is not steady across the day. It typically peaks in the early morning and declines through the afternoon and evening, so a single measurement is most informative when the collection time is known and consistent with the question being asked.
A blood cortisol test is commonly used to investigate suspected adrenal insufficiency, in which production is too low, or cortisol excess, in which production is too high. It may also be ordered to monitor conditions or treatments that affect adrenal function.
Results are rarely diagnostic in isolation. Clinicians often combine a cortisol measurement with other laboratory studies, such as ACTH or dynamic stimulation and suppression tests, to determine whether an abnormal level originates in the adrenal glands or in the regulatory pathways that control them.
