BIOSENSOR AND METHODS FOR MANUFACTURING
First Claim
1. A biosensor adapted to detect an analyte in a body fluid sample, comprising:
- a single-piece body with two end surfaces;
at least two electrical conductors embedded within the single-piece body and extending between the two end surfaces, the at least two electrical conductors being exposed at the two end surfaces to define exposed portions of the at least two electrical conductors; and
a reagent disposed on one of the end surfaces and on the exposed portions of the at least two electrical conductors.

Abstract
A biosensor for detecting an analyte in a sample of body fluid and methods for manufacturing the biosensor are disclosed. In one embodiment, a biosensor includes at least two electrical conductors embedded within an electrically insulating test element body. The electrical conductors are exposed at two ends of the test element body and a reagent, for example a reagent adapted to test for blood glucose, is applied to one end. In one form, the test element body is cylindrical with a circular or non-circular cross-sectional shape. In other embodiments, the test elements are manufactured by a resin pultrusion process in which resin embedded with electrical conductors is dried or cured, shaped and cut into segments, and reagent applied to one end of each segment.
