Abstract

Multiple analytes may be dysregulated singularly or concurrently in certain physiological conditions and may be advantageously assayed together using analyte sensors capable of detecting multiple analytes. Certain analyte sensors capable of the detection of multiple analytes may include first and second working electrodes, analyte-responsive active areas disposed on each of the working electrodes, and reference and counter electrodes. Analyte sensors that include multiple working electrodes but do not include reference and counter electrodes can also be used in conjunction with another sensor that contains reference and counter electrodes, such that these electrodes are shared.
