Patent ID: 8222044

Claim:
A method of manufacturing a plurality of test strips, comprising: (a) providing a web of base substrate material; (b) forming a plurality of electrode sets on the web of base substrate material; (c) providing a reagent layer covering at least one electrode of each electrode set; (d) depositing a film of spacing material having a series of cavities defined therein such that each one of the cavities aligns with a respective one of the electrode sets on the web of base substrate material, each of the cavities having a flared portion that comprises a location for a fluid receiving opening and an elongated portion extending from the flared portion, the location for the fluid receiving opening has a first width and the elongated portion has a second width, wherein the first width is greater than the second width; (e) attaching a covering layer to the film of spacing material to create a series of capillary chambers defined by the series of cavities in the spacing material, the web of base substrate material, and the covering layer; and (f) cutting the web into the plurality of test strips.
