Abstract
By making a bilirubin oxidase derived from the genus Pleurotus to act on a living body fluid sample in the presence of at least one of a cationic surfactant such as alkyltrimethylammonium salt, etc. and a nonionic surfactant such as polyoxyethylenealkyl ether, etc., only bilirubin non-.delta. fractions of the living body fluid sample can be oxidized, while keeping a bilirubin .delta. fraction remaining as unreacted. Thus, the bilirubin non-.delta. fractions and .delta. fraction of the living body fluid sample can be exactly quantitatively determined by action of the bilirubin oxidase on the sample.
