<p>Provided is a prozone phenomenon detecting method, by which generation of a prozone phenomenon can be detected even when a conventional specimen analysis tool is used, and examinations using an immunochromatography method and the like can be performed efficiently. In the method, a specimen analysis tool containing substances that specifically bind to a target component contained in a sample is used. The specimen analysis tool is obtained by arranging a sample supplying portion, a reagent portion, and a detection portion on the porous base material from upstream to downstream in a sample moving direction in this order. The reagent portion contains a labeled substance that specifically binds to the target component. The detection portion contains an immobilized substance that specifically binds to the target component. The target component is detected by detecting a complex of the target component, the labeled substance, and the immobilized substance through detection of a label of the labeled substance in the detection portion. The method includes at least one of the following processes A and B: the process A: a process in which detection results obtained in the detection portion are plotted along the sample moving direction, and generation of a prozone phenomenon is detected on the basis of a position of a peak in plots thus obtained; and the process B: a process in which the label is detected at two or more different time points in the detection portion, and generation of a prozone phenomenon is detected on the basis of a magnitude relationship between two or more detection results thus obtained.</p> |
