CPT® Code 86334

The CPT® Code 86334 refers to the procedure known as immunofixation electrophoresis (IFE) performed on serum. This laboratory test is designed to detect and analyze specific proteins in the blood, particularly focusing on identifying abnormal proteins, the absence of normal proteins, and variations in the levels of certain protein groups. The test is particularly valuable in diagnosing a range of medical conditions, including inflammatory disorders, autoimmune diseases, acute or chronic infections, and various kidney and liver disorders. Additionally, it is instrumental in identifying protein-losing conditions and multiple myeloma, a type of blood cancer characterized by the proliferation of abnormal plasma cells. The process involves obtaining a blood sample through a separate venipuncture, which is a procedure where a needle is inserted into a vein to draw blood. Once the serum is collected, it undergoes qualitative immunofixation electrophoresis, a technique that separates proteins based on their size and charge, allowing for the identification of specific protein abnormalities. The results obtained from this test should be interpreted in conjunction with quantitative immunoglobulin level tests and other relevant clinical or laboratory data to provide a comprehensive understanding of the patient's health status. It is important to note that while CPT® Code 86334 pertains specifically to serum testing, there is a related code, CPT® Code 86335, which is used for performing the same test on urine, cerebrospinal fluid (CSF), or other body fluids, particularly for identifying Beta-2 transferrin, a marker indicative of cerebral spinal fluid leaks.
