Abstract:
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 method includes dosing the test sensor with the fluid sample; applying a signal to the first electrode pair and the second electrode pair, detecting a first response to the signal from the first electrode pair, and detecting a second response to the signal from the second electrode pair; determining a time period between the first response and the second response and then applying a measurement test sequence for an analyte of interest on the fluid sample if the time period is less than a first predetermined threshold.
