    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.

    摘要: A blood test apparatus has a housing, a blood sensor, and a plurality of connectors. The blood sensor has a plurality of connection terminals that are electrically connected with each electrode of the electrode system; and a reference terminal that serves as a reference. The plurality of connectors are configured to connect to the plurality of connection terminals and the reference terminal of the blood sensor attached at a predetermined position in the blood test apparatus, respectively. And also, relations between the reference terminal and each of the plurality of connection terminals are measured to identify the reference terminal automatically.

    摘要: It is intended to provide a means of easily removing a portion of blood bleeding from pierced skin, which has not been taken into a blood sensor but remained on the skin, in a blood test with the use of a blood test apparatus. By using this means, it becomes unnecessary in the blood test to separately prepare a paper sheet, etc. for wiping off. More specifically speaking, a blood test apparatus wherein a blood sensor is provided within a blood sensor unit detachable to the blood test apparatus body and the blood sensor unit has a part to be in contact with the skin in the test and an absorption means. It is favorable that the part to be in contact with the skin in the test serves as the absorption means.
