ABSTRACT:
The invention concerns a method for the simultaneous colorimetric and electrochemical measurement of an analyte using an oxidizing enzyme and a chromogen A that accepts electrons from the enzyme which is characterized in that the chromogen A after reduction to A' reacts by coupling to a substance BX to form a colored substance A'B the concentratin of which is measured colorimetrically as a measure for the presence or amount of the analyte and in that an electrochemically measurable group X.sup.- is cleaved off during the coupling reaction the concentration of which is measured electrochemically as a measure for the amount of the analyte.
