CPT® Code 82286

The CPT® Code 82286 refers to a laboratory test specifically designed to measure the levels of bradykinin in the blood. Bradykinin is a biologically active peptide that plays a significant role in various physiological processes, including vasodilation, which is the widening of blood vessels, and the contraction of non-vascular smooth muscle found in areas such as the bronchial tubes and the gastrointestinal tract. Additionally, bradykinin is known to increase vascular permeability, allowing substances to pass through blood vessel walls more easily, and it is involved in the synthesis of prostaglandins, which are compounds that have various effects on the body, including inflammation and pain modulation. Bradykinin is typically broken down in the body by several enzymes, including angiotensin-converting enzyme (ACE), aminopeptidase P (APP), and carboxypeptidase N (CPN). Elevated levels of bradykinin can indicate certain medical conditions, particularly hereditary angioedema, a genetic disorder that causes severe swelling, as well as in patients experiencing tissue injury, chronic pain, or various inflammatory disorders. The test for bradykinin is performed on a blood sample, which is obtained through a procedure known as venipuncture. This sample is then analyzed using a method called enzyme-linked immunosorbent assay (ELISA), which is a common laboratory technique used to detect and quantify proteins, hormones, and other substances in biological samples.
