Disclosed is an improved method for the detection of creatinine in a fluid test sample by contacting the test sample with cupric ions, a hydroperoxide, citrate and an oxidizable dye which gives a colored response in the presence of oxygen free radicals and a pseudoperoxide. The improvement involves stabilizing the reagent formulation by the addition thereto of an ionizable phosphate containing compound such as phytic acid. |
