Abstract

To perform measurement based on polarization anisotropy in which a reaction between a target substance and a luminescent reagent is performed within a short period of time, and in which high-sensitivity measurement can be performed, provided is an analysis method including measuring a value (R) for polarization anisotropy through use of a luminescent reagent that reacts with a target substance, to thereby determine at least any one of the presence or absence of the target substance and a concentration of the target substance, the analysis method including: a reaction step of mixing a sample containing the target substance with the luminescent reagent, and subjecting the mixture to a reaction to obtain a reaction liquid; a dilution step of diluting the reaction liquid to obtain a diluted liquid; and a measurement step of measuring the R of the diluted liquid, the luminescent reagent including luminescent particles.
