Biosensor comprising electrode for measuring hematocrit value

A biosensor comprising:

• an enzyme electrode containing a detection layer, the detection layer comprising an enzyme, an electrically conductive polymer and a crosslinking agent;
• a counter electrode;
• a reference electrode;
• and
• a hematocrit electrode configured to measure a hematocrit value in a blood sample, wherein:
• the electrically conductive polymer is physically adsorbed as a coating on a surface of the hematocrit electrode via a non-covalent bond,
• the electrically conductive polymer is configured to transfer electrons received from the blood sample to the electrode,
• the crosslinking agent contains at least one functional group selected from the group consisting of an aldehyde group, a maleimide group, a carbodlimide group, an oxazoline group, an epoxy group and combinations thereof, and
• the coating does not contain a crosslinking agent.
