[Immunoelectrophoresis or immunofixation: identification of monoclonal gammopathy]

Both methods enable the clinical laboratory to identify monoclonal gammapathies with a good sensitivity. The immunofixation method, more quickly used than the immunoelectrophoresis, is easier to obtain the best resolution. It is well adjust for the characterization of low concentration gammapathies like immunoglobulin light chains. Immunofixation appears to take a more and more important place in the clinical laboratory.
