1. A method of manufacturing a test strip having first and second sides, a sample-receiving end and a meter insertion end, and a central longitudinal axis extending between the two ends, the method comprising:

  • (a) providing a web of base substrate material having first and second web edges;

    (b) forming an electrode set on the web comprising a working electrode and a counter electrode;

    (c) applying a stripe of reagent material to the web and covering at least one electrode of the electrode set with the stripe, the stripe being oriented substantially parallel to the first web edge; and

    (d) laminating a web of spacing material on top of the base substrate material and providing a cavity in the spacing material such that the electrode set is received within the cavity and the cavity at least partially defines a sample receiving chamber;

    (e) aligning and then laminating a web of covering layer material over the web of base substrate and spacing material; and

    (f) cutting a test strip from the laminated web produced from steps (a)-(e), the cutting defining the first and second sides of the test strip, wherein the test strip comprises a reagent layer extending to the first and second sides of the test strip under the spacing layer.
