Interpretive Data:
Caution: Immunofixation electrophoresis is a more sensitive technique than serum protein electrophoresis for the identification of small M-proteins found in patients with amyloidosis, early or treated myeloma and macroglobulinemia, solitary plasmacytoma, and extramedullary plasmacytoma.



Note:
Serum protein patterns with monoclonal or suspicious patterns will be tested by immunofixation electrophoresis which is more sensitive in determining and defining monoclonal proteins.  Patterns which are normal, polyclonal, or lacking monoclonal patterns will not be tested by IFE.

CPT Code(s):
84160 Total protein; 84165 Electrophoretic fractionation; if reflexed add 82784 x3 IgA, IgG, and IgM and 86334 IFE
