ABSTRACT:
The present invention provides a method for quantifying a substrate having improved measurement accuracy and measurement sensitivity. According to the method for quantifying the substrate of the present invention, a constant voltage is applied to an electrode system, between a working electrode and a counter electrode, via a resistor connected in series with the electrode system after placing a sample solution containing the substrate on the electrode system, so as to oxidize an electron acceptor, which has been reduced by an enzyme reaction of the substrate, thereby determining a concentration of the substrate included in the sample solution based on an oxidizing current flowing in the course of oxidation.
