  • Patent number: 11268926
    Abstract: 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.
