Abstract
The present invention provides a method for measuring a component to be measured in a sample, comprising converting the component to be measured in the sample into hydrogen peroxide and measuring the formed hydrogen peroxide in the presence of an α-keto acid using an oxidative-coloring chromogen. The present invention also provides a method for suppressing the influence of a peroxide on a method of converting a component to be measured in a sample into hydrogen peroxide and measuring the formed hydrogen peroxide using an oxidative-coloring chromogen, the suppression method comprising using an α-keto acid. The measuring method and the suppression method of the present invention using an α-keto acid suppress the influence of a peroxide to give an accurate measurement of the component to be measured in the sample.
