A monoclonal IgM of greater than 3 g/dL is consistent with macroglobulinemia. a homogeneous immunoglobulin resulting from the proliferation of a single clone of plasma cells; during electrophoresis of serum, it appears as a narrow band or "spike"; it is characterized by heavy chains of a single class and subclass and by light chains of a single type. For example, if a Monoclonal Antibody binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that Monoclonal Antibody to protein X is equal to 29.

A monoclonal protein is produced by the abnormal, cancerous or precancerous cells. In addition, if the patient is asymptomatic and has a diagnosis of MGUS, the expanded monoclonal protein study panel provides the information (size of M-spike, monoclonal protein isotype, FLC K/L ratio) needed for a MGUS progression risk assessment (see Interpretation). Hypereosinophilic syndrome (HES) refers to a group of blood disorders caused by high levels of eosinophils. A monoclonal protein is. Because MGUS is not harmful, it doesnt need to be treated.
