Includes identification of monoclonal gammopathies and
pathologist interpretation.

Immunofixation electrophoresis of serum 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.
Pathologist may order quantitative immunoglobulins to further
evaluate any monoclonal protein detected.
