1. A biosensor used to measure presence or concentration of an analyte in a fluid sample, said biosensor being produced by:

  • (a) providing an electrically conductive material on a base;

    (b) removing a portion of the electrically conductive material by broad field laser ablation to form an electrode set on the base wherein the biosensor having the electrode set includes at least two co-planar electrodes on the base;

    (c) providing a reagent at least partially covering the base; and

    (d) adhering one or more layers to the base, the one or more layers cooperating to form a sample-receiving chamber and a cover for the biosensor, at least a portion of both the reagent and the electrode set being positioned in the chamber.
