**Results can take 5 to 7 Business days.

Electrophoresis followed by immunodiffusion against monospecific antisera to immunoglobulin and individual heavy and light chain (IFE); turbidimetric quantitation of IgA, IgG, and IgM

Immunofixation electrophoresis of serum or urine is most often ordered to evaluate a monoclonal globulin detected in a protein electrophoresis or to delineate a possible lymphoproliferative process, particularly myeloma. This procedure will characterize the specific light and heavy chain components of a monoclonal protein.
