The present invention provides a system of biosensors whose dose-response curves are maintained within a predetermined and desired range or tolerance during production by selecting a feature of the biosensors that can be varied during production. For example, in one exemplary embodiment the effective area of the working electrode of an electrochemical biosensor can be varied during production as needed to offset variations that occur, e.g., in the reagent of the biosensors as production proceeds. In another exemplary embodiment, the dose-response curve of biosensors not yet produced can be predicted and one or more features of these biosensors can be selected to maintain the dose-response curve within a predetermined range or tolerance.
