  • Method and instrument for measuring blood sugar level
    Patent number: 6493069
    Abstract: A blood sugar measuring instrument for measuring the blood sugar level of blood on the basis of change in the color of the reagent having reacted with the blood. The instrument irradiates light onto a specimen to which blood is applied, detects the intensity of the reflected light with a photo detector, determines absorbency from the specimen every one second after the specimen has started coloring by the applied blood, and calculates the blood sugar level of the blood applied to the specimen on the basis of the absorbency when change in the absorbency has become 2% or less.
