    摘要: Electrode arrangements for test elements, test elements and methods of determining sample sufficiency, monitoring fill time, establishing fill directions and/or confirming electrode coverage by a sample for test elements are disclosed. The test elements have an electrode-support substrate including a spacer having an edge defining a boundary of a capillary channel. The electrode-support substrate also includes a first electrode pair and a second electrode pair, wherein the first electrode pair is positioned between the second electrode pair. The first electrode pair including a first counter electrode and a first working electrode, and the second electrode pair including a first and a second indicator electrode.
    The method includes dosing the test sensor with the fluid sample; applying a signal to (1) the counter electrode and the first indicator electrode, (2) the first electrode pair, and (3) the counter electrode and the second indicator electrode, wherein the counter electrode and the first indicator electrode are configured to transmit a first response, the first electrode pair is configured to transmit a second response, and the counter electrode and the second indicator electrode are configured to transmit a third response; detecting an initial response to the signal, wherein the initial response is the first one of the first, second and third responses detected; detecting a final response to the signal, wherein the final response is the last one of the first, second and third responses detected; determining a time period between the initial response and the final response; and applying a measurement test sequence for the analyte of interest on the fluid sample if the time period is less than a first predetermined threshold.
