1. A method for identifying an interfering species using an analyte-measuring device, the method comprising:

  • providing at least one electrochemical sensor;

    measuring a first signal output obtained at a first bias potential setting;

    measuring a second signal output obtained at a second bias potential setting;

    comparing the first signal output with the second signal output to determine a differential measurement, thereby identifying a presence of an interfering species in a liquid; and

    calculating an analyte concentration from the differential measurement, wherein the step of calculating is performed when interfering species are positively identified, and wherein the interfering species are positively identified when the differential measurement is above a set threshold.
