Immunoassay method and immunoassay apparatus

An immunoassay apparatus comprising:

• a detector configured to detect, by measuring a measurement specimen obtained by mixing a sample and carrier particles together, information regarding a binding number of the carrier particles included in the measurement specimen, the carrier particles having immobilized thereon an antibody or an antigen against a measurement target substance;
• and
• a controller having a processor and a memory programmed to perform operations comprising:
• classifying, based on the information regarding the binding number, particles included in the measurement specimen into groups, the groups being classified in accordance with the binding numbers;
• performing, on at least one of the classified groups, at least one of a first removing process for removing, from a processing target, data of non-target substances different from the carrier particles, and a second removing process for removing, from the processing target, data of the non-target substances through a process different from the first removing process;
• and
• obtaining information regarding an agglutination degree of the carrier particles, based on data of the carrier particles obtained by performing the at least one removing process.
