METHOD FOR BILIRUBIN DETERMINATION AND ANALYTICAL INSTRUMENT USED FOR BILIRUBIN DETERMINATION

摘要

A method for assaying bilirubin in which a dry reagent is used, which is capable of accelerating the reaction of bilirubin oxidase, and an assay instrument to be used in the method for assaying bilirubin, are provided. The method for assaying bilirubin is characterized in that a biological sample and a bilirubin oxidase-containing dry reagent are mixed first, and then the mixture obtained and a surfactant-containing dry reagent are mixed. An assay instrument (1) to be used in bilirubin assay is characterized in that a bilirubin oxidase and a surfactant are arranged in any of a sample supply part (11), passages (12, 13, 14), and a detection part (15) in a manner such that the bilirubin oxidase is positioned closer to the sample supply part (11) than the surfactant is.
