1. A method for determining the concentration of an analyte in a sample, the method comprising:

  • receiving a sample to an analyte sensor, wherein the analyte sensor comprises a working electrode and a counter electrode;

    electrolysing the sample;

    measuring current as a function of time;

    predicting a first total signal value for complete electrolysis of the analyte from the measured current decay prior to a first time during electrolysis and an extrapolated current decay subsequent the first time during electrolysis;

    determining a data collection endpoint, wherein the data collection endpoint is a predetermined percentage of the predicted first signal value;

    measuring current until the data collection endpoint;

    calculating a second total signal value from the measured current decay prior to the data collection endpoint and an extrapolated current decay subsequent the data collection point; and

    determining the concentration of the analyte based on the calculated second signal value.
