Abstract
A process of calibrating a blood sugar analyzing apparatus, in which the blood sugar concentration in a blood specimen is measured with a fixed enzyme membrane sensor and corrected by calibration means, said blood sugar analyzing apparatus providing a linear relationship between measured and actual blood sugar concentrations in a range of blood sugar concentrations which are lower than a predetermined blood sugar concentration, and producing a deviation from said linear relationship in a range of blood sugar concentrations higher than said predetermined blood sugar concentration, in that said process comprises the steps of effecting a plurality of measurements of standard solutions having known low blood sugar concentrations in said blood sugar analyzing apparatus, obtaining an average value of the results of the measurements with said calibration means, determining a first correction coefficient (k.sub.1) to correct a deviation of said average value from the reference blood sugar concentration, thereafter measuring a blood specimen, and multiplying the result of the measurement by said correction coefficient with said calibration means when said result of the measurement is less than said predetermined blood sugar concentration and by a second calibration coefficient (K.sub.2) when the result of the measurement exceeds said predetermined blood sugar concentration.
