Claim:
1. A method for measuring a concentration of an analyte in a blood sample using a sensor chip, the sensor chip including a capillary and a pair of electrodes, the method including: acquiring data a related to a temperature of the blood sample, based on a dimension of a current flowing in the blood sample by applying a first voltage to the pair of electrodes in contact with the blood sample, the first voltage being set so as to reduce an effect of hematocrit on a temperature measurement result; acquiring data b related to the concentration of the analyte, based on a dimension of a current flowing in the blood sample by applying a second voltage that is equal to or less than the first voltage, utilizing a reaction mediated by an oxidoreductase that uses the analyte in the blood sample as a substrate; and measuring a concentration that determines the analyte concentration in the blood sample based on the data a and the data b, wherein the first voltage is between 1.0V and 3.0V, and the second voltage is between 0.05V and 1.0V.
