Light Guide Test Sensor

Abstract

An optic light guide test sensor comprises a light guide, a reagent-coated membrane, and a mesh layer. The reagent-coated membrane and the mesh layer are attached to the light guide at an output end of the light guide. The light guide test sensor is adapted to be used to test the level of an analyte in a biological fluid sample when used with a readhead. A method of manufacturing the light guide test sensor involves providing a plurality of light guides, providing a strip of reagent-coated membrane, and providing a strip of mesh layer. The reagent-coated membrane and mesh layer are attached to the light guides by ultrasonic welding. The reagent-coated membrane and mesh layer may also be attached to the light guides by adhesive.

1 . An optic light guide test sensor comprising:
 a light guide having an input end and an output end;   a reagent-coated membrane, the membrane being located at the output end of the light guide and being attached to the light guide, the reagent being adapted to react with a fluid sample to indicate the level of an analyte in the sample; and   a mesh layer being attached to the membrane.
