Official Description

Chondroitin B sulfate, quantitative

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The laboratory test for chondroitin B sulfate is indicated for the assessment of various conditions related to connective tissue and cardiovascular health. Elevated levels of chondroitin B sulfate may suggest the presence of atherosclerotic plaque, which can be classified into different types based on their hardness. This test may be utilized in the evaluation of patients with suspected cardiovascular diseases or those exhibiting symptoms related to connective tissue disorders.

  • Atherosclerosis Elevated levels may correlate with the presence and typology of atherosclerotic plaque.
  • Connective Tissue Disorders Useful in assessing conditions affecting connective tissues.

2. Procedure

The procedure for measuring chondroitin B sulfate quantitatively involves several key steps to ensure accurate results. Initially, a blood sample is collected from the patient, typically through venipuncture. This sample is then processed in a laboratory setting where it undergoes specific analytical techniques designed to isolate and quantify the chondroitin B sulfate present in the serum. The laboratory may employ methods such as enzyme-linked immunosorbent assay (ELISA) or mass spectrometry, depending on the facility's capabilities and the required sensitivity of the test. After the analysis is complete, the results are compiled and interpreted by a qualified laboratory professional, who will report the findings to the requesting physician for further evaluation and clinical decision-making.

  • Step 1: Sample Collection A blood sample is obtained from the patient through venipuncture.
  • Step 2: Sample Processing The blood sample is processed in the laboratory to prepare it for analysis.
  • Step 3: Analytical Testing Specific techniques, such as ELISA or mass spectrometry, are used to quantify chondroitin B sulfate.
  • Step 4: Result Interpretation A qualified laboratory professional interprets the results and prepares a report for the physician.

3. Post-Procedure

Post-procedure care for patients undergoing the chondroitin B sulfate test is generally minimal, as it is a routine laboratory test. Patients may experience slight discomfort or bruising at the venipuncture site, which typically resolves quickly. There are no specific restrictions or follow-up procedures required after the test, and patients can resume their normal activities immediately. The results of the test will be communicated to the healthcare provider, who will discuss the implications of the findings and any necessary further actions based on the patient's clinical context.
