Abstract

See full text

In a biosensor having a developing layer for developing a sample solution, including a reagent part immobilized to a portion of the developing layer and a marked reagent part which is held in a dry state by a portion of the developing layer, and is dissolvable by developing the sample solution, and qualitatively or quantitatively analyzing an analyte in the sample solution by measuring the amount of the marker reagent bound to the reagent immobilization part; wherein plural reagent immobilization parts exist, and the respective reagent immobilization parts have different affinities for the analyte in the sample solution or the marker reagent, whereby a prozone phenomenon can be detected. Further, a biosensor with a high precision of measurement, which has a wider dynamic range for the concentration of the analyte in the sample solution, can be provided. Thereby, a highly accurate and precise biosensor which can detect a prozone phenomenon even when the range of the concentration of the analyte in the sample solution is wide, and has a wide measurement dynamic range can be provided.
