CPT® Code 82485

The CPT® Code 82485 refers to a laboratory test that quantitatively measures chondroitin B sulfate, a specific type of glycosaminoglycan (GAG). Chondroitin B sulfate is a complex molecule composed of polysaccharides linked to amino acids, which are essential components of the extracellular matrix found in various tissues, including skin, cartilage, corneal tissue, and the umbilical cord. This matrix serves multiple functions, providing mechanical support to tissues while facilitating the diffusion of water-soluble molecules and the migration of cells. The presence of glycosaminoglycans, such as chondroitin B sulfate, is crucial for maintaining the homeostasis of connective tissues, influencing neurobiochemical activities, and playing roles in coagulation, cell growth, and tissue repair. Notably, elevated levels of chondroitin B sulfate in the body may be indicative of certain pathological conditions, particularly in relation to atherosclerosis, where they may correlate with the presence and characteristics of atherosclerotic plaques, distinguishing between hard and soft types.
