Abstract:
1. A method for measuring reaction results of a sample using a biosensor having two working electrodes and one reference electrode, comprising: sequentially supplying respective working electrodes with a power supply voltage and measuring a time interval from when an amount of current flowing in a first working electrode begins to be detected until a time when an amount of current flowing in a second working electrode begins to be detected; displaying an error message when the measured time interval exceeds a predetermined critical range; sequentially re-supplying the respective first and second working electrodes with the power supply voltage when the measured time interval is within the predetermined critical range, and re-detecting the amounts of current flowing in the respective first and second working electrodes; reading concentrations corresponding to the amount of current from a memory and calculating an average value from the read concentrations; and checking whether a difference between each of the concentrations read from the memory and an average value exceeds a predetermined critical value to display one of an error message and the calculated average value.
