摘要： The present invention provides a method for accurately measuring a blood component despite uneven distribution of blood introduced into a capillary. The measurement method according to the present invention is characterized in that a plurality of electrode systems for measuring the hematocrit are provided in a capillary of a biosensor to measure the hematocrit at different positions in the capillary. By measuring the hematocrit at the plurality of positions in the capillary as described above, the hematocrit can be measured mom accurately despite uneven distribution of blood introduced into the capillary.

摘要： This sensor is for measuring an analyte and has a probe to be inserted inside a living body. The probe of the sensor includes a substrate, an electrode formed on the substrate, and a reagent layer that contains an oxidoreductase and that is formed on the electrode. At at least one end of the probe in the width direction, the reagent layer and the electrode are trimmed along the insertion direction of the probe toward the inside of the living body.

摘要： It is intended to provide, for example, a liquid sample measurement device capable of measuring the amounts of components of a liquid with a high accuracy. A first voltage is applied to an electrode pair 21, 22, which composes a biosensor 1, to obtain a first response value, a second voltage is applied to an electrode pair 23, 24, which composes the biosensor 1, to obtain a second response value, and a current that is generated when a third voltage is applied to an electrode pair 23, 27, which composes the biosensor 1, is detected to obtain a third response value. A liquid sample measurement device 6 uses the first response value, the second response value, and the third response value to obtain the concentration of glucose and the amount of blood cells of blood as well as the value equivalent to the temperature of the biosensor 1.
