1. A method for determining an analyte in a bodily fluid sample, the method comprising:

  • applying a bodily fluid sample to an electrochemical-based analytical test strip having;

    an electrically insulating base layer; and

    a patterned conductor layer disposed over the electrically-insulating layer, the patterned conductor layer including at least one electrode;

    wherein the at least one electrode has electrochemically inert areas, an electrically continuous electrochemically active area lattice, and non-conductive border regions separating the electrochemically inert areas and the electrically continuous electrochemically active area lattice, the electrochemically inert areas and electrically continuous electrochemically active area lattice being configured of a predetermined size and a predetermined distribution such that an electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response of a screen-printed carbon electrode;

    measuring an electrochemical response of the electrochemical-based analytical test strip; and

    determining the analyte based on the measured electrochemical response.
