A method of determining concentration of an analyte in a fluid sample deposited on a sensor device having a working electrode and a counter electrode, in which the electrodes are provided with an enzyme and a mediator for carrying out a mediated redox reaction, comprises: applying a first oxidising potential 220 between the working and counter electrodes during a first time period; applying a second reducing potential 230 between the working and counter electrodes during a second time period; determining a reaction parameter 240 which is indicative of the concentration of reduced mediator at the counter electrode after commencement of the second time period; and using the reaction parameter to determine the concentration of analyte 250. |
