Method for measuring temperature of biological sample, measuring device, and biosensor system
The concentration measurement method includes: introducing a predetermined amount of the biological sample into the capillary; measuring a temperature of the biological sample by applying a first voltage to the electrode unit when the temperature of the biological sample is measured, the first voltage allowing the temperature measurement to be less affected by increase and reduction in an amount of the analyte contained in the biological sample; measuring the concentration of the analyte contained in the biological sample by applying a second voltage to the electrode unit; measuring an environmental temperature in a surrounding of the biological sample; and correcting the concentration of the measured analyte based on the measured temperature of the biological sample and the measured environmental temperature.
