Abstract

PURPOSE:To enhance the accuracy of measurements in biochemical inspection, by comparing the analytical values of 1 wavelength colorimetry and 2 wavelength colorimetry and correcting or re-inspecting them in order to eliminate interference due to 3 major obstacle and interference due to air bubbles and solied matter. CONSTITUTION:The reaction liquid of serum is colorimetrically analyzed by 1 wavelength colorimetry and 2 wavelength colorimetry, and the ratio of the two methods is calculated. When the ratio is in the specified range closer to 1, for instance, within 0.95 to 1.05, the one of the analytical values or the mean of the two analytical values is adopted as the result of analysis. At this time, from the spectrum of analytical item in which the analysis of the spectrum is easiest, the chyle index, hemolytic index and icterus index of the obstacle are obtained. If the ratio of the analytical values is beyond the specified range, the both analytical values are corrected according to the mass of the obstacle contained in the specimen, and when the ratio of corrected analytical values is within 0.95 to 1.05, the corrected analytical values are adopted as the result of analysis. If the ratio of corrected analytical values is other than 0.95 to 1.05, the corrected analytical value of 2 wave length colorimetry is adopted, or the measurement is taken again.
