A sensor and a method for assessing a sample are disclosed. The sensor comprises an on-board control system and a testing system within a single reaction chamber. The control system comprises at least one control reagent selected from iodine, ascorbate, ferricyanide, ferrocyanide, 4-amino-2-chlorophenol, or a combination thereof, and the at least one control reagent is not an N-oxide compound and is free of nitroso functional groups. The control system comprises a control reaction involving the control reagent, and the control reaction generates a control signal, and the control signal indicates viability of at least one of the control system and/or the testing system, and the control reagent employed in the control reaction is not available to a reaction of the testing system. |
