PROBLEM TO BE SOLVED: To provide a method of measuring an analyte in a sample by using a redox reaction, capable of providing a highly reliable measured value. SOLUTION: A tetrazolium compound is added to a sample prior to the redox reaction so as to eliminate the influence of any reducing substance in the sample, then a reducing substance or an oxidizing substance derived from the analyte is formed, the quantity of the formed substance derived from the analyte is measured by the redox reaction, and the quantity of the analyte is determined from the quantity of the formed substance derived from the analyte. As the tetrazolium compound, for example, 2-(4-iodophenyl)-3-(2,4-dinitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium salt can be used. COPYRIGHT: (C)2007,JPO&INPIT
