SPECIFIC COMPONENT CONCENTRATION MEASURING METHOD AND CONCENTRATION MEASURING INSTRUMENT

摘要

The present invention relates to a method for measuring a concentration of a specific component. The method comprises: a first step of supplying a sample fluid to a reaction field holding a reagent; a second step of obtaining a single or a plurality of electric currents for correction, through a measurement of electric current made once or a plurality of times (S6) without applying a voltage to the reaction field (S5); a third step of obtaining a single or a plurality of electric currents for calculation, through a measurement of electric current made once or a plurality of times (S11) while applying a voltage to the reaction field (S9); and a fourth step of calculating a concentration of a specific component in the sample fluid, based on the single or the plurality of values for correction and the single or the plurality of values for calculation (S14). Preferably, the fourth step reflects an average or cumulative value of the electric currents for correction on a calculated result of the concentration of the specific component. The present invention also relates to a concentration measuring apparatus performing the above-described measuring method.
