ABSTRACT:
An improved colorimetric assay method and reagent composition for the quantitative determination of creatinine in biological fluid specimens in the presence of protein, in which the specimen is reacted directly with an alkaline picrate reagent composition which contains an iron chelator, preferably ethylenediaminetetraacetic acid, thereby significantly suppressing interference from bilirubin and improving reagent stability.
