Provided is a method for measuring the concentration of a substance in a blood sample, the method comprising the steps of: supplying the blood sample to a biosensor comprising a hematocrit electrode for measuring a hematocrit value on the surface of which electrode an electrically conductive polymer is coated by physical adsorption in the absence of a crosslinking agent; and calculating the concentration of the substance from the measured value of a first current resulting from application of a first voltage; and correcting the concentration of the substance with the value of a second current resulting from application of a second voltage or the hematocrit value calculated from the value of the second current.

Biosensor comprising electrode for measuring hematocrit value

A biosensor includes a plurality of electrodes including a working electrode, and a detection layer which is immobilized on the working electrode and contains a crosslinking agent, an electrically conductive macromolecule and an enzyme transferring and receiving electrons to and from the working electrode. The working electrode is in an open system.

Biosensor

Provided is a method for measuring the concentration of a substance in a blood sample, comprising: supplying the blood sample to a biosensor comprising a hematocrit electrode for measuring a hematocrit value on the surface of which electrode an electrically conductive polymer is covalently immobilized; and calculating the concentration of the substance from the measured value of a first current resulting from application of a first voltage; and correcting the concentration of the substance with the value of a second current resulting from application of a second voltage or the hematocrit value calculated from the value of the second current.
