Serum protein electrophoresis in Waldenström macroglobulinemia
Serum protein electrophoresis in Waldenström macroglobulinemia
The figure shows a serum protein electrophoresis (SPEP) pattern in a patient with Waldenström macroglobulinemia with a monoclonal (M) protein in the gamma region (asterisk). Immunofixation (IFE) shows that the M protein is IgM kappa.
