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, supports the body's response to stress, and contributes to blood pressure and immune function. Because cortisol follows a daily rhythm, a blood test measures the amount present at the moment of collection and is interpreted alongside the time of day the sample was drawn.
About Cortisol Levels Blood Test in Tigard
The Cortisol Levels Blood Panel measures the concentration of cortisol in a blood sample.
Cortisol is synthesized in the adrenal cortex and circulates bound largely to corticosteroid-binding globulin, with a smaller free fraction that is biologically active. Secretion rises sharply in the early morning and declines through the day, so reference intervals are typically defined by collection time.
A blood cortisol measurement is used to evaluate suspected adrenal insufficiency, where levels may be low, and to investigate excessive cortisol production, where levels may be elevated or fail to suppress normally. Results are usually considered together with clinical findings and may be followed by additional testing such as ACTH stimulation or dexamethasone suppression.
Several factors can influence a cortisol result, including the time of collection, acute illness, physical or emotional stress, pregnancy, and medications such as corticosteroids or oral contraceptives. The laboratory's instructions regarding timing and any required preparation should be followed so the sample is collected under the intended conditions.
