Quizplus · Accepted Answer

In multiple myeloma, malignant plasma cells produce excess amounts of abnormal antibodies, known as monoclonal or M-proteins. In about 73% of patients with multiple myeloma, the M-protein in the urine is composed of light chains, which are called Bence Jones proteins. Therefore, an elevated value in the urine protein confirmatory test is likely due to the presence of Bence Jones protein. The other choices are not typically associated with multiple myeloma.
