WebBence Jones proteins (monoclonal free light chains of immunoglobulins) are the earliest known biological markers of malignant cell dyscrasia; Bence Jones proteinuria is also present in many types of B cell-related neoplasms. WebSummary: If a monoclonal protein is identified, its immunoglobulin class (IgG, IgA, IgM, IgD, IgE) and light chain type (kappa, lambda) are determined by immunofixation. MGUScauses no symptoms. 3. The FLC assay is specific for free kappa and lambda light chains and does not recognize light chains bound to intact immunoglobulin. High IGA (7.09 g/l), and low IGG (3.05) and low IGM (.15). They may also notice unusual levels of protein in your urine. Antibodies are a type of protein responsible for fighting off infections and disease in the body.

Unfortunately it means you need further testing. In these situations, quantitative IgG assays more accurately determine M-spike concentrations for monitoring disease progression or response to therapy. A diagnosis of MGUS without any other symptoms usually does not call for more testing. While a small amount is normal, a large amount of protein in urine may indicate kidney disease.

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. 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. Although the PEL M-spike is the recommended method of monitoring monoclonal gammopathies, IgA and IgM proteins that are contained in the beta fraction may be more accurately monitored by quantitative immunoglobulins. Mayo Clinic Staff. People with monoclonal gammopathy generally don't experience signs or symptoms. MGUS usually causes no problems.
