MGUS is defined as the presence in the serum of an M-protein < 30 g/L, bone marrow clonal plasma cells < 10%, no end organ damage, and no evidence of B-cell lymphoma or other disease known to produce an M-protein. This process is not considered neoplastic since it does not always progress to overt malignancy.
