1. A method for determining if the parasitic resistance in a conductive trace of a biosensor is acceptable, the method comprising the steps of:

  • a) coupling the biosensor into a test meter;

    b) coupling a first end of a known resistance to a first end of the first conductive trace;

    c) applying a voltage to a second end of the first conductive trace;

    d) measuring a current flowing at a second end of the known resistance;

    e) uncoupling the first end of the known resistance from the first end of the first conductive trace while the biosensor is coupled to the test meter;

    f) calculating a parasitic resistance of the first conductive trace using the applied voltage, the measured current, and the known resistance; and

    g) comparing the calculated parasitic resistance to a predetermined threshold.
