Abstract:
1. A method for detecting an analyte in a sample comprising the steps of: introducing the sample into a test cell of an electrochemical test strip for detection of the analyte comprising: applying a potential between the working and counter electrodes, but not to the conductive region of the second substrate, thereby reducing an oxidized form of the redox mediator at the counter electrode and oxidizing a reduced form of the redox mediator at the working electrode, thereby generating a current indicative of analyte in the sample; wherein the overall transfer of electrons from the counter electrode to the working electrode is accomplished by diffusion of reduced mediator from the counter electrode to the conductive region of the second substrate and then diffusion of reduced mediator from the conductive region of the second substrate to the working electrode, and measuring the current to obtain a determination of analyte in the sample.
