1. A method for forming an optical test sensor to be used with an optical analysis system, the method comprising the acts of:
- providing a base and a second layer, the base and the second layer assisting in forming a channel for receiving a fluid sample;
providing a reagent material with an oxidizable species therein;
applying voltage to the reagent material via an electrochemical system to oxidize the oxidizable species therein and form a modified reagent material having a reduced background current as compared to a reagent material where voltage has not been applied via an electrochemical system; and
placing the modified reagent material to assist in forming the optical test sensor, the modified reagent material being placed in the channel of the optical test sensor so as to contact the fluid sample,wherein the reagent material includes a mediator and an enzyme.

Abstract
Systems and methods for electrochemically oxidizing components of a test-sensor reagent prior to deposition on a test sensor comprise at least a first electrode and a second electrode for contacting the test-sensor reagent. The first electrode and the second electrode may have hollow interior portions for contacting the test-sensor reagent to produce a modified test-sensor reagent having a reduced background current.
