Method of measuring quantity of substrate
First Claim
1. A method of measuring a quantity of a substrate, comprising the steps of:
- i) providing a biosensor which includes a reagent layer reacting specifically with a substrate included in a measurement sample;
ii) providing a measuring device for measuring the quantity of the substrate, wherein the measuring device includes;
a temperature measuring section for measuring a temperature while the reaction between the reagent layer and the measurement sample progresses; and
a temperature compensation data memory having a plurality of measurement compensation tables which are different in different temperature ranges;
iii) selecting one of the compensation tables according to a combination of a temperature measured by the temperature measuring section and a concentration of the substrate;
iv) calculating a compensation value corresponding to a measured value of the substrate; and
v) compensating the measured value of the substrate with the calculated compensation value.

Abstract
A method of measuring a quantity of a substrate contained in sample liquid is provided. This method can reduce measurement errors caused by a biosensor. The biosensor includes at least a pair of electrodes on an insulating board and is inserted into a measuring device which includes a supporting section for supporting detachably the biosensor, plural connecting terminals to be coupled to the respective electrodes, and a driving power supply which applies a voltage to the respective electrodes via the connecting terminals. One of the electrodes of the biosensor is connected to the first and second connecting terminals of the measuring device only when the biosensor is inserted into the measuring device in a given direction, and has a structure such that the electrode becomes conductive between the first and second connecting terminals due to a voltage application by the driving power supply.
