    摘要: The present biosensor system prevents a measurement error caused by the temperature of the environment in use. A biosensor system 100 includes a measuring instrument 101 having an operation part 306, and a sensor chip 200 insertable into and removable from the measuring instrument 101 and which accepts a blood sample. The sensor chip 200 includes a measurement part 41 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 sample due to a reaction in which an oxidoreductase with the analyte used as a substrate is involved, and a measurement part 42 that acquires, from the sample, Data b for temperature correction of Data a. The operation part 306 determines the concentration of the analyte in the sample, corrected according to the temperature of the sample based on Data a and Data b.
