Measurement method using oxidase

摘要

A method for measuring a target object in a sample by using an oxidase, wherein the influence of dissolved oxygen in the sample can be corrected, is provided. The method comprises: obtaining measurement values by causing the target object in the sample to react with the oxidase under different conditions of two or more types; and performing a correction based on the obtained two or more measurement values and a correction method preliminarily set so as to correct the influence of dissolved oxygen in the sample.

1. A biosensor comprising:
two or more independent electrode systems, where each electrode system comprises a working electrode and a counter electrode in contact with a substrate; and two or more different reagent layers, where each reagent layer comprises an oxidase and a mediator and is provided on the working electrode and the counter electrode of each independent electrode system, and where each reagent layer differs in the type or amount of at least one of the oxidase and the mediator, and wherein the biosensor is capable of measuring a single target object present in a single sample under different conditions, where the sample contains dissolved oxygen.
