  A highly reliable method of measuring an analyte in a sample using a redox reaction. In this method, 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.

  一种高度可靠的测量样品中分析物的方法，使用氧化还原反应。在该方法中，在氧化还原反应之前向样品中添加四唑化合物以消除样品中任何还原物质的影响，然后形成从分析物中衍生的还原物质或氧化物质，通过氧化还原反应测量从分析物中衍生的物质的数量，并从中确定分析物的数量。例如，可以使用2-（4-碘苯基）-3-（2,4-二硝基苯基）-5-（2,4-二硫酚基）-2H-四唑盐作为四唑化合物。

  A method of determining an analyte in a sample utilizing a redox reaction is provided, by which a highly reliable determined value can be obtained. In this method, a tetrazolium compound is added to a sample in the presence of a surfactant prior to a redox reaction so as to eliminate an effect of hemoglobin and a hemoglobin degradation product as reducing substances in the sample. Thereafter, a reducing or oxidizing substance derived from an analyte is produced and the amount thereof is determined by the redox reaction. Then, the amount of the analyte in the sample is determined based on the amount of the reducing or oxidizing substance thus determined. According to this method, cloudiness due to the coexistence with the hemoglobin can be prevented by the surfactant and thus an increase in the absorbance due to the cloudiness can be inhibited as shown in FIG. 1 . As the surfactant, polyoxyethylene ether and the like can be used.

  提供了一种利用氧化还原反应确定样品中分析物的方法，可以获得高度可靠的确定值。在这种方法中，在氧化还原反应之前，在表面活性剂的存在下向样品中加入四唑化合物，以消除血红蛋白和血红蛋白降解产物作为还原物质对样品的影响。然后，由分析物产生的还原或氧化物质被产生，并通过氧化还原反应确定其数量。然后，根据确定的还原或氧化物质的数量确定样品中分析物的数量。根据这种方法，由于表面活性剂可以防止与血红蛋白的共存而导致的浑浊，因此可以像图1所示那样抑制由于浑浊而导致的吸光度增加。作为表面活性剂，可以使用聚氧乙烯醚等。

  A reagent is suitable for measuring the concentration of an analyte in a hemoglobin-containing biological fluid, such as whole blood. The reagent comprises dehydrogenase enzyme that has specificity for the analyte, NAD or an NAD derivative, a tetrazolium dye precursor, a diaphorase enzyme or an analog thereof, and a nitrite salt. The reagent causes dye formation that is a measure of the analyte concentration. The nitrite salt suppresses interfering dye formation caused non-enzymatically by the hemoglobin. Preferably, the reagent is used in a dry strip for measuring ketone bodies, such as beta-hydroxybutyrate.
