Abstract
The present invention provides a biosensor system that can prevent a measurement error caused by the temperature of the environment in use from occurring. A biosensor system 100 includes a measuring instrument 101 having an operation part 306, and a sensor chip 200 that is insertable into and removable from the measuring instrument 101 and into which a blood sample is introduced. The sensor chip 200 includes a measurement part 41 (a measurement part A) that acquires Data a related to the concentration of an analyte in a blood sample based on the amount of electric current that flows in the blood sample due to a reaction in which an oxidoreductase with the analyte used as a substrate is involved, and a measurement part 42 (a measurement part B) that acquires, from the blood sample, Data b for temperature correction of Data a. The operation part 306 has a function of determining the concentration of the analyte in the blood sample, with the concentration having been corrected according to the temperature of the blood sample based on Data a and Data b.

20. A biosensor system, comprising:
-
a measuring instrument having an operation part; and a sensor chip that is insertable into and removable from the measuring instrument and into which a blood sample is introduced, wherein the sensor chip comprises a measurement part A including an electrode A and an electrode B; a measurement part B including the electrode A and an electrode C, a reaction reagent layer formed on the electrodes A and B but not on the electrode C, and a spacer formed on the reaction reagent layer;
whereinthe measuring instrument does not include an environmental temperature measurement part for measuring the environmental temperature; the measurement part A acquires Data a related to a concentration of an analyte in the blood sample based on the amount of electric current that flows in the blood sample due to a reaction in which an oxidoreductase with the analyte used as a substrate is involved; the measurement part B acquires Data b suitable for temperature correction of the Data a; the operation part is configured to determine the concentration of the analyte in the blood sample based on the Data a, as corrected based on the Data b measured by measurement part B, thereby avoiding the influence of the temperature of the blood sample in the measurement of the analyte concentration. - View Dependent Claims (21, 22, 23, 24, 25)
