Immunofixation (IFE), Urine

Detect and identify monoclonal immunoglobin gammopathies.

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 help identify the specific light and heavy chain components of a monoclonal protein.
