Interpretation upon detection Blood serum paraprotein levels of more than 3 g/l is diagnostic of smouldering myeloma, an intermediate in a spectrum of step-wise progressive diseases termed plasma cell dyscrasias. Elevated paraprotein level (above 3 g/l) in conjunction with end organ damage (elevated calcium, kidney failure, anemia, or bone lesions) or other biomarkers of malignancy, is diagnostic of multiple myeloma, according to the diagnostic criteria of the International Myeloma Working Group, which were updated in 2014. Detection of paraprotein in serum of less than 3 g/l is classified as monoclonal gammopathy of undetermined significance in cases where clonal plasma cells constitute less than 10\% on bone marrow biopsy and there is no myeloma-related organ or tissue impairment.
Interpretation upon detection Blood serum paraprotein levels of more than 30 g/l is diagnostic of smouldering myeloma, an intermediate in a spectrum of step-wise progressive diseases termed plasma cell dyscrasias. Elevated paraprotein level (above 30 g/l) in conjunction with end organ damage (elevated calcium, kidney failure, anemia, or bone lesions) or other biomarkers of malignancy, is diagnostic of multiple myeloma, according to the diagnostic criteria of the International Myeloma Working Group, which were updated in 2014. Detection of paraprotein in serum of less than 30 g/l is classified as monoclonal gammopathy of undetermined significance in cases where clonal plasma cells constitute less than 10\% on bone marrow biopsy and there is no myeloma-related organ or tissue impairment.
