Protein Electrophoresis with Pathologist Interpretation, Serum or Urine
Test Code3951122
CPT Codes
84165-Electrophoresis, protein; 86334-Immunofixation electrophoresis, protein, serum (if appropriate); 86335-Immunofixation electrophoresis, protein, urine (if appropriate)
Includes
Includes protein, total with electrophoresis for quantitation of albumin, alpha-1, alpha-2, beta- and gamma globulins, and pathologist’s comments. If monoclonal gammopathy is detected, #717 Immunofixation Electrophoresis with Pathologist Interpretation, Serum or Urine will be performed and charged separately (unless monoclonal gammaglobulin has been previously identified and on record).

Clinical Significance
This test is primarily used for detection of monoclonal gammopathies, low gamma globulins, and abnormalities in the other normally occurring protein patterns; for evaluation of serum protein evaluation, nutritional status, and diffuse polyclonal gamma globulin; and in the work-up for liver disease.
