Clinical Significance
Electrophoresis is used to identify the presence of abnormal proteins, to identify the absence of normal proteins, and to determine when different groups of proteins are increased or decreased in serum. It is frequently ordered to detect and identify monoclonal proteins – an excessive production of one specific immunoglobulin. Protein electrophoresis and immunofixation are ordered to help detect, diagnose, and monitor the course and treatment of conditions associated with these abnormal proteins, including multiple myeloma and a few other related diseases.
Protein electrophoresis testing provides a rough estimate of how much of each protein is present. Immunofixation testing provides the identification of monoclonal proteins that may be present.
