Light guide test sensor

An optic light guide test sensor comprising:

• a light guide having an input end and an output end,
• a reagent-coated membrane, 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 reagent membrane,
• wherein the light guide includes protrusions located at the output end, the protrusions being made of a meltable material and assisting in attaching the reagent-coated membrane and the mesh layer to the output end of the light guide.
