1. A biosensor for measuring a constituent concentration in blood, said biosensor comprising, on a support substrate:

  • a sample reception region for receiving a blood sample;

    at least one electrode; and

    a reaction reagent system comprising, in a gel matrix;

    an oxidation-reduction enzyme specific for the constituent; and

    at least one electron mediator capable of being reversibly reduced and oxidized such that an electrochemical signal resulting from the reduction or oxidation is related to the constituent concentration in the blood sample,wherein said gel matrix is sufficient to prevent at least some of the red cells in the blood sample from contacting the electrode.
