TEST REAGENT, AND METHOD FOR MEASURING ANALYTE IN TEST SAMPLE USING SAME

WIPO Patent Application WO/2010/101213

A1

Disclosed is a test reagent for an analyte in a test sample. The test reagent employs, as an indicator, the occurrence of the aggregation of particles in a particle-floating solution in which particles comprising insoluble carrier particles and an analyte-capturing substance supported on the insoluble carrier particles are floating, does not undergo self-aggregation during storage, and rarely undergoes non-specific aggregation during measurement. Also disclosed is a method for measuring an analyte in a test sample using the test reagent. Specifically disclosed is a test reagent for measuring an analyte, which comprises at least a solution (A) and a solution (B), wherein the solution (A) is a buffer solution having an electrical conductivity of 30 ms/cm or more and the solution (B) is a particle-floating solution in which particles comprising insoluble carrier particles and an analyte-capturing substance supported on the insoluble carrier particles are floating and has an electrical conductivity of 6.5 ms/cm or less.
