Patent ID: 7641785

Claim:
A method of measuring a blood component, comprising: bringing a sample containing blood into contact with a reagent containing an oxidoreductase that reacts with the blood component in the blood, a mediator, and a hemolyzing agent for hemolyzing an erythrocyte; detecting a current generated by mixing of the sample and the reagent, the current being detected by electrodes; and converting the detected current value into an amount of the blood component, wherein the mixing of the sample and the reagent causes a redox reaction between the blood component in the blood and the oxidoreductase, hemolysis of the erythrocyte in the blood and a reaction between hemoglobin released to an outside of the erythrocyte and the mediator, wherein detecting the current generated by mixing detects the current value that has been corrected to remove an effect of a hematocrit, and wherein the amount of the blood component obtained by converting the detected current value is the blood component amount that has been corrected to remove the effect of the hematocrit.
