IMPROVED DETECTION METHOD OF CREATININE

摘要

PROBLEM TO BE SOLVED: To provide an improved reagent system for detecting creatinine in a fluid sample in which an inclination that hemoglobin and/or ascorbate cause a false-positive result and an automatic oxidation of an oxidizing/reducing dye is reduced. SOLUTION: An verification method of creatinine in a fluid sample including a process of contacting the fluid sample may contain creatinine with a cupric ion hydroperoxide and a dye to be oxidized includes a substituted quinoline compound for inhibiting an automatic oxidation of a dye to be oxidized at a presence of the cupric ion in a measuring system.
