The automatic analyzer includes: a sample dispensing unit that dispenses a sample into a reaction vessel; a reagent dispensing unit that dispenses a reagent into the reaction vessel; a control unit that controls the sample dispensing unit and the reagent dispensing unit; and a measurement unit that measures a mixed solution of the sample and the reagent mixed in the reaction vessel. The reagent includes three types of reagents of: a first reagent that specifically binds to an antigen in the sample; a second reagent that specifically binds to a site different from that to which the first reagent binds with respect to the antigen and has a label to be detected by the measurement unit; and a third reagent that specifically binds to a site different from the binding site of the first reagent and the antigen and contains insoluble carriers.

Automatic analyzer and analysis method

In conventional automatic analyzers, there have been instances where, when a plurality of associated items are analyzed as a set item, there is high variation in the analysis data obtained using the set item, leading to a need for improvement of analysis precision. The present invention comprises performing, in mutual association, a set of preparation steps to carry out until it is time to analyze an unknown sample, the set of preparation steps including a pre-preparation step in which stirring, etc., is performed when an analysis reagent kit is mounted on the analyzer, and a step for correcting a standard curve in which correction samples that correspond to analysis items are used. This makes it possible to perform analysis after the preparation states of a plurality of analysis reagent kits are collected as needed, enabling high-precision analysis of a set item.
