Abstract

A procedure for detecting proteins in fluids (particularly body fluids) which involves contacting such fluid with a composition comprising copper in a form capable of forming a copper/protein complex, a peroxide and a redox indicator which provides a detectable response when oxidized, together with an ionizable phosphate containing compound to prevent interference with the redox indicator from substances present in the fluid.
