Question

Quizplus · Accepted Answer

Bence-Jones proteins are monoclonal free light chains that can be identified in the urine and are often indicative of multiple myeloma. MGUS (Monoclonal gammopathy of undetermined significance) is a condition in which an abnormal protein, known as an M spike, is present in the blood, but it doesn't meet the criteria for multiple myeloma or other related conditions. Heavy chains are part of the structure of antibodies and are not typically found free in the urine.
