CPT® Code 82528

The CPT® Code 82528 refers to a laboratory test specifically designed to measure the levels of corticosterone in the blood. Corticosterone is a type of glucocorticoid hormone that is synthesized by the adrenal glands, which are located on top of each kidney. This hormone serves as a precursor to another important hormone known as aldosterone, which is classified as a mineralocorticoid. The secretion of corticosterone is regulated by the renin-angiotensin system, a hormone system that plays a crucial role in regulating blood pressure and fluid balance in the body. Additionally, corticosterone is involved in various physiological processes, including brain function and metabolism. In terms of its presence in the body, corticosterone is primarily found circulating in the bloodstream, with only minimal amounts stored in bodily tissues. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is separately reportable. The analysis of the serum or plasma obtained from the blood sample is conducted using a sophisticated technique called quantitative high performance liquid chromatography-tandem mass spectrometry, which allows for precise measurement of corticosterone levels.
