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 stress response. Because cortisol follows a daily rhythm, the timing of a blood draw can affect the result, and clinicians often interpret a single measurement alongside the time of collection and the reason the test was ordered.
About Cortisol Levels Blood Test in Petaluma
Cortisol levels blood testing measures the concentration of cortisol circulating in the bloodstream at the moment of collection.
The adrenal glands secrete cortisol in a diurnal pattern, with concentrations typically highest in the early morning and lowest late in the day. A blood test captures a single point in that cycle, so the collection time is recorded and considered when results are reviewed.
Cortisol testing may be requested when there are signs or symptoms that suggest the adrenal glands are producing too much or too little cortisol. These can include unexplained weight change, fatigue, changes in blood pressure, or other findings that prompt a clinician to evaluate adrenal function.
Results are interpreted in context. A value outside a laboratory's reference interval does not by itself establish a diagnosis, and additional testing or clinical correlation may be needed to clarify what the measurement means for an individual.
