1. An electrochemical test sensor for detecting the concentration of an analyte in a fluid test sample, the electrochemical test sensor comprising:

  • a base that provides a flow path for the fluid test sample having on its surface a counter electrode and a working electrode adapted to electrically communicate with a detector of electrical current;

    a dielectric layer forming a dielectric window therethrough;

    a reagent layer including an enzyme that is adapted to react with the analyte; and

    a lid adapted to mate with the base and to assist in forming a capillary space with an opening for the introduction of the fluid test sample thereto,wherein the lid includes a light guide area adapted to transmit light from a first end of the test sensor towards the capillary space.
