Abstract
Disclosed is a method of measuring sample reaction results on a biosensor having a working electrode and other electrodes, including: applying voltage between the working electrode and each of the other electrodes and detecting the amount of current flowing through the working electrode to determine whether or not a sample is injected; applying voltage between the working electrode and one of the other electrodes and re-detecting the amount of current flowing through the working electrode; and acquiring and displaying a concentration value as a sample reaction result corresponding to the amount of detected current.
