What does This has to be examined carefully. It is not cancer. Ifx shows no monoclonal protein & free light chains are within normal range. Finding M proteins in the blood or urine is usually a sign of disease. Immunofixation electrophoresis (IFE) is performed to identify the immunoglobulin heavy chain and/or light chain. Monoclonal In multiple myeloma, cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells. There is no risk of monoclonal gammopathies in first-degree family members. This is often done with a lab test called electrophoresis. Most people who have abnormal proteins in their blood will never get worse. IFE characterizes the type of monoclonal protein (gamma, alpha, mu, delta, or epsilon heavy chain; kappa [K] or lambda [L] light chain). Once a monoclonal gammopathy has been diagnosed, the size of the clonal abnormality can be monitored by PEL or FLC and, in some instances, by quantitative immunoglobulins.

In the United States, MGUS affects about 3 percent of people above age 50. With the addition of the serum free light-chain (FLC) assay, the expanded monoclonal protein study provides even more diagnostic sensitivity for the monoclonal light-chain diseases such as primary amyloid and light-chain deposition disease; disorders that often do not have serum monoclonal proteins in high enough concentration to be detected and quantitated by PEL.
