1. A method of performing a measurement on a biological fluid in a test strip comprising:

  • providing a biological fluid test strip including a capillary fill chamber extending a length along the test strip from an intake opening to a terminus, a first pair of electrodes in operative communication with the chamber, and a second pair of electrodes in operative communication with the chamber;

    dosing the test strip with a biological fluid effective to cause the biological fluid to flow from the intake opening toward the terminus;

    applying a first test signal to one of the first pair of electrodes;

    measuring a first response to the first test signal at the other of the first pair of electrodes;

    maintaining the first pair of electrodes in an inoperative state upon the measuring the first response;

    applying a second test signal to one of the second pair of electrodes;

    measuring a second response to the second test signal at the other of the second pair of electrodes; and

    performing a measurement upon the biological fluid after the measuring the second response.
