1. A method of determining dosage fill level in a test strip for performing a measurement on a biological fluid comprising:

  • providing a biological fluid test strip, comprising;

    a capillary fill chamber extending a length along the test strip from an opening to a terminus, andat least two pairs of dose sufficiency electrodes in operative communication with the chamber, each of the pairs of dose sufficiency electrodes positioned to define a respective gap between one another;

    dosing the test strip with a biological fluid effective to cause the biological fluid to begin to fill the chamber;

    applying a test signal to at least one electrode of each of the dose sufficiency electrode pairs;

    measuring a respective response to the test signal at each of the dose sufficiency electrode pairs;

    determining the dosage fill level based upon the responses.
