METHOD FOR QUANTITATIVE ANALYSIS USING ANALYTICAL ELEMENT SHEET

摘要

An improvement in a method for quantitative analysis of an analyte contained in a liquid sample such as whole blood, plasma or serum, which comprises applying a certain amount of a liquid sample onto an anlytical element in the form of a sheet comprising a reagent-retaining layer provided on a transparent support and photometrically measuring a change of color density or a rate of the change of color density from the transparent support side to determine quantitatively the amount of the analyte in the liquid sample. The Improvement comprises correcting a fundamental value photometrically determined in tne conventional manner, by applying thereto a correction value determined from a previously determined relationship between a supplementary value measured on the analytical system and a certain influential factor, whereby obtaining an analytical result improved in accuracy.
