This content does not have an English version. What does this mean? Low-risk MGUS patients are defined as having an M-spike of less than 1.5 g/dL, IgG monoclonal protein, and a normal FLC K/L ratio (0.25-1.65), and these patients have a lifetime risk of progression to MM of less than 5%. Because MGUS usually causes no symptoms, it's usually detected by chance during blood tests for other conditions. Results should always be interpreted in conjunction with other laboratory tests and clinical evidence; any anomalies should be discussed with the testing laboratory. WebThe presence of M protein in the blood typically indicates the presence of multiple myeloma, or other plasma cell disorders such as amyloidosis or MGUS. Includes total protein, serum protein electrophoresis, and heavy-chain and light-chain typing (kappa and lambda).

Data from the Mayo Clinic showed that the median survival of MGUS patients was 8.1 years compared to 11.8 in the comparable US population. In fact, monoclonal protein in the blood is often found by accident when doing other routine blood work. If a monoclonal light chain is detected in the absence of an associated monoclonal heavy chain, an immunofixation electrophoresis specific for delta and epsilon chains is performed. Created for people with ongoing healthcare needs but benefits everyone. Monoclonal gammopathy of undetermined significance (MGUS). (Package insert: Sebia Hydrasys Hydragel 1, 2, 4, 9IF, Sebia Inc; 09/2015), The quantitation of free light chain (FLC) by turbidimetry uses FLC antisera. High blood protein rarely causes signs or symptoms on its own. 4. Immunofixation electrophoresis (IFE) is performed to identify the immunoglobulin heavy chain and/or light chain.

However, if the monoclonal protein falls within the beta region (most commonly an IgA or an IgM) quantitative immunoglobulin levels may be more a useful tool to follow the monoclonal protein level than PEL. (2017). These cancerous cells rapidly spread and crowd out the normal antibodies with M proteins, overtaking the healthy cells. In these situations, quantitative IgG assays more accurately determine M-spike concentrations for monitoring disease progression or response to therapy.
