Performance validation of mass spectrometry for detecting urinary Bence Jones protein and evaluation of its clinical application in multiple myeloma and amyloidosisYu Chenon July 28, 2026 at 10:00 am

July 28, 2026 by ccinfoadmin

Clin Chem Lab Med. 2026 Jul 29. doi: 10.1515/cclm-2026-0469. Online ahead of print. ABSTRACT OBJECTIVES: Traditional urine immunofixation electrophoresis (uIFE) is cumbersome, has limited sensitivity, and is subjectively interpreted. This is especially problematic in renal impairment where accumulation of polyclonal free light chains may pseudonormalize the serum free light chain (sFLC) ratio, compromising its reliability … Read more
