1. A biosensor comprising:

  • an enzyme electrode configured to measure a glucose concentration in a blood sample, wherein a surface of the enzyme electrode is in contact with a detection layer comprising an oxidoreductase enzyme, a first electrically conductive polymer and electrically conductive particles; and

    a hematocrit electrode configured to measure a hematocrit value in the blood sample, wherein the hematocrit electrode comprises a metal layer or a carbon layer formed on an insulating base plate and wherein a second electrically conductive polymer is covalently immobilized on a surface of the metal layer or the carbon layer by a crosslinking agent.
