Method for measuring temperature of biological sample, measuring device, and biosensor system

摘要

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.

1. A concentration measurement method of measuring a concentration of an analyte contained in a biological sample in a sensor chip including (i) an electrode unit including at least a working electrode and a counter electrode, the electrode unit including a reagent containing an electrolyte, and (ii) a capillary allowing the biological sample to be introduced therein, the concentration measurement method comprising:
an introduction of introducing a predetermined amount of the biological sample into the capillary; a first temperature measurement of 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 being higher than a voltage to be applied in measuring a concentration of glucose in the biological sample, which the first voltage allows the temperature measurement to be less affected by increase and reduction in an amount of the analyte contained in the biological sample; a concentration measurement of measuring the concentration of the analyte contained in the biological sample by applying a second voltage to the electrode unit, the second voltage being applied in measuring the concentration of the glucose; a second temperature measurement of measuring, using a thermistor, an environmental temperature in a surrounding of the biological sample; and a correction of correcting the concentration of the analyte measured in the concentration measurement based on the temperature of the biological sample measured in the first temperature measurement and the environmental temperature measured in the second temperature measurement.
