Interpretive Data
Serum protein electrophoresis, when used as a screening test, is useful in the detection of various pathophysiologic states such as inflammation, protein loss, gammopathies, and other dysproteinemias. However, immunofixation electrophoresis (IFE) is a more sensitive technique for the identification of small M-proteins found in patients with amyloidosis, early or treated myeloma or macroglobulinemia, solitary plasmacytoma, or extramedullary plasmacytoma.
