Historical perspectives in clinical pathology: Bence Jones protein-early urine chemistry and the impact on modern day diagnostics

Abstract

This is the third in the series of historical articles dealing with developments in clinical pathology. Bence Jones proteins are immunoglobulin light chains found in excessive quantities in urine in multiple myeloma and are believed to be one of the first tumour markers ever discovered . Dr Henry Bence Jones is credited with the discovery of this protein in 1847 that bears his name and he can also be regarded as the first chemical pathologist/clinical chemist. Since then, numerous advances and refinements have been made in the measurement and detection of urine light chain proteins which have resulted in the current sensitive serum free light chain assays used today.
