Patent ID: 8506775

Claim:
In a test strip for measuring the concentration of an analyte in a bodily fluid, the test strip defining a capillary passageway, the passageway being dimensioned so as to induce movement of a sample of bodily fluid along a predetermined path through the passageway extending inwardly from an entrance at an edge of the test strip, the improvement comprising: providing a first set of electrodes in electrical communication with the passageway, the first set of electrodes including at least two electrodes separated by a distance of less than 50 μm; providing a second set of electrodes in electrical communication with the passageway, the second set of electrodes including at least two electrodes separated by a distance greater than 50 μm; and a reagent located within the capillary passageway, the reagent combining with the bodily fluid to produce a redox reaction, said reagent being located over at least one of the first and second sets of electrodes, and the other of the first and second sets of electrodes either having said reagent located thereover or having no reagent located thereover.
