Abstract:
1. A method for determining the concentration of a reduced or oxidized form of a redox species, said method comprising the steps of: (1) disposing a blood sample on an electrochemical apparatus comprising a hollow electrochemical cell for measuring a concentration of glucose in the blood sample, the hollow electrochemical cell comprising: (2) applying an electric potential difference between the working electrode and the counter electrode or counter/reference electrode that causes at least one of: (3) measuring a current between the working electrode and the counter electrode or counter/reference electrode; and (4) determining the concentration of the reduced or oxidized form of the redox species from at least, the rate of electro-oxidation of the reduced form of the redox species when the working electrode is kept sufficiently anodic or the rate of electro-reduction of the oxidized form of the redox species when the working electrode is kept sufficiently cathodic.
