Quizplus · Accepted Answer

Bence Jones proteins are abnormal immunoglobulins produced by the malignant plasma cells in plasma cell myeloma. They are filtered through the kidneys and excreted in the urine, which can be detected by urine protein electrophoresis. Therefore, the presence of Bence Jones proteins in the urine is a diagnostic laboratory finding in plasma cell myeloma. Decreased platelet count (thrombocytopenia) is a common complication of myeloma, but it is not a specific diagnostic finding. Increased IgM antibody titer is associated with Waldenstrom macroglobulinemia, a type of lymphoma, but not with plasma cell myeloma. Elevated blood glucose levels can occur in some patients with myeloma, but it is not a diagnostic laboratory finding.
