Abnormal bands in the electrophoretic pattern of serum proteins, primarily those in the beta-globulin and gamma-globulin zones, are always suspect of being monoclonal proteins and therefore an indication of gammopathies. Immunofixation is used as a method to identify these bands.
*Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Due to the resolution and sensitivity limits of immunofixation, it is possible that some monoclonal components may not be detected with this method.
Collect specimen in SST tube. Centrifuge, aliquot serum into a plastic vial and refrigerate. If cryoglobulin is suspected, the specimen must be drawn in a red top tube and maintained at 37 degrees C.
Test includes pathologist interpretation of results billed as a separate additional charge. This test is not available without interpretation. In order to provide accurate interpretation, additional testing components are required and billed as separate charges. These components include a Total Protein Electrophoresis (TPE), Protein, Total (PROT), and Immunoglobulins IgG, IgA and IgM (IGS).
