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 pronounced daily rhythm, a blood test is typically interpreted against the time of collection and the clinical context rather than as a single fixed number.
About Cortisol Levels Blood Test in Danville
The Cortisol Levels Blood Test measures the concentration of cortisol in a blood sample to help assess adrenal and pituitary function.
Cortisol is secreted in a diurnal pattern, with concentrations usually highest in the early morning and lowest in the late evening. Reference intervals are therefore time-dependent, and results are most meaningful when the collection time is recorded and considered alongside the reason for testing.
Measurement of blood cortisol is used in the evaluation of suspected adrenal insufficiency, in which production is inadequate, and in states of cortisol excess such as Cushing syndrome. It may also be ordered when symptoms suggest a disrupted adrenal axis, including unexplained fatigue, weight change, easy bruising, or blood pressure that is difficult to control.
A single cortisol value is rarely diagnostic on its own. Clinicians often combine it with other findings, such as ACTH measurement, dynamic stimulation or suppression procedures, or salivary and urinary cortisol testing, to distinguish among conditions that can produce similar results.
