Reference Range:
Negative for monoclonal proteins. The serum IFE report will include a
descriptive report of abnormalities, if present.
Comments:
Serum immunofixation electrophoresis methodology switched from
traditional gel electrophoresis to capillary electrophoresis on
September 24, 2012. Technically, the method used in capillary
electrophoresis to identify monoclonal proteins is known as
immunotyping. This methodology can resolve IgA, IgG, and IgM heavy
chains, as well as kappa and lambda light chains. Monoclonal
gammopathies involving IgD and IgE are rare but can occur. Contact
pathology resident at page #3725 if additional workup may be needed
for workup of suspected IgD or IgE gammopathy.
