Patent ID: 8721850

Claim:
A biosensor adapted to detect an analyte in a body fluid sample, comprising: a single-piece, electrically-insulating, elongated body having a uniform, alignment-selective, cross-sectional shape throughout its length, and having a first orthogonal end surface at a first end of the body and a second orthogonal end surface at the second end of the body, the alignment-selective, cross-sectional shape constituting a body registration feature for orienting said body in a predetermined position relative to a receptacle in which said body is placed; at least two electrical conductors embedded and electrically insulated completely along their length within the single-piece body and extending between the first and second end surfaces of the body, the at least two electrical conductors having exposed first end surfaces flush and coplanar with the first end surface of the body and exposed second end surfaces flush and coplanar with the second end surface of the body; and a reagent disposed on the exposed first end surfaces of the at least two electrical conductors, the reagent being configured to electrochemically react with a body fluid sample applied to the reagent, and wherein the reagent is in electrical communication with the electrical conductors when the body fluid is applied to the reagent.
