Abstract

We report two cases of immunoglobulin light chain proteinuria (Bence Jones proteinuria) detected by simple side-room investigations: urine dipstick negative/1+, but with strong positive precipitation on addition of an equal volume of sulphosalicylic acid (SSA) 3%. We
highlight a significant limitation of urine dipstick testing, namely specificity for albumin, and the utility of SSA testing for the detection of urinary free light chain immunoglobulins.
