Abstract
A method is provided for verifying test element integrity includes providing a biosensor having an electrode-support substrate. A first electrode is provided on the substrate that includes a first body and a neck extending from the first body. A second electrode is provided on the substrate that includes a second body and an opposite pair of necks. Each of the necks extends from a respective end of the second body. A spacer is positioned on the substrate and has an edge defining a boundary of a capillary channel formed between a cover and the substrate. The method also includes applying a signal across the necks of the second electrode to verify continuity along the second electrode. The second body of the second electrode and the pair of connective necks surround the first electrode in the capillary channel forming a loop circuit around the first electrode.
