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 regulating blood pressure, immune activity, and the sleep-wake cycle. Because cortisol follows a daily rhythm, a blood test measures the amount present at the moment the sample is drawn.
About Cortisol Levels Blood Test in Harlingen
A cortisol blood test measures the concentration of cortisol circulating in the bloodstream.
Cortisol production is governed by the hypothalamic-pituitary-adrenal axis. The hypothalamus releases corticotropin-releasing hormone, the pituitary responds with adrenocorticotropic hormone, and the adrenal glands then secrete cortisol. This chain of signals helps keep cortisol within a workable range throughout the day.
Cortisol is not released at a constant level. It typically peaks in the early morning and declines through the day, reaching its lowest point late at night. Because of this pattern, the time of collection matters when interpreting a result, and a single measurement is often considered alongside the clinical picture rather than in isolation.
Testing may be used to evaluate suspected adrenal or pituitary conditions, such as excessive or insufficient cortisol production. Results can be affected by factors including stress, medications, pregnancy, and the timing of the draw, so the ordering clinician interprets the value in context.
