Order Cortisol Levels Blood TestCortisol is a steroid hormone produced by the adrenal glands and released under the influence of the pituitary hormone ACTH. It helps regulate carbohydrate, protein, and fat metabolism, moderates the body's response to stress, and contributes to blood pressure and immune function. Because cortisol follows a predictable daily rhythm, measuring its concentration in blood can help clinicians evaluate whether the adrenal and pituitary axes are working as expected.
About Cortisol Levels Blood Test in Cupertino
A cortisol blood test measures the amount of cortisol circulating in the bloodstream at the time of collection.
Cortisol output rises and falls across the day, typically peaking in the early morning and reaching its lowest point late at night. For this reason, the time of collection matters, and results are interpreted against the reference range associated with that collection time. A single measurement reflects only one moment, so clinicians often combine it with the clinical picture or additional testing.
Blood cortisol is used to investigate suspected adrenal insufficiency, in which the glands produce too little cortisol, and conditions of cortisol excess such as Cushing syndrome. It may also be ordered when symptoms suggest a disruption in the pituitary or adrenal pathways, including unexplained fatigue, weight change, low blood pressure, or unusual pigmentation.
Results are not read in isolation. Medications, acute illness, pregnancy, and the stress of the collection itself can shift cortisol concentrations. When a borderline or unexpected value appears, the clinician may request repeat sampling, a timed collection, or a related test such as ACTH to clarify the underlying picture.
