The present invention provides a method capable of simultaneous processing of plural test samples for the receptor binding property of a chemical substance, which does not require immobilization of the receptor or a special device, and a reagent to be used for this method. That is a method for assaying the receptor binding property of an assay target substance is provided, the method comprising the steps of (a) competitively reacting a known concentration of a ligand and the assay target substance with a known concentration of the receptor in a solution, (b) measuring, without physically removing the ligand bound with the receptor prior to the assay, the amount of a free ligand in the solution using one or more antibodies against the ligand, and (c) determining the receptor binding property of the assay target substance using the amount of the free ligand as an index.

Disclosed is a process for measuring an amount of all bilirubins in a specimen, comprising deconjugating conjugated bilirubins with a reagent comprising an enzyme capable of deconjugation to form the unconjugated bilirubin, and determining an amount of the unconjugated bilirubin in the specimen, and a reagent therefor. The present invention also provides a process for measuring an amount of the unconjugated bilirubin in a specimen, comprising oxidizing and eliminating conjugated bilirubins in the specimen with an oxidizing agent capable of oxidizing bilirubins, in the presence of a metal ion forming a complex with the bilirubins and a surfactant at pH 6.5 or less, and determining an amount of the unconjugated bilirubin in the specimen, and a reagent therefor.
