Abstract
Biosensor systems including a measurement device and test sensors including at least three independently addressable electrodes, with at least two of the electrodes being substantially chemically isolated are disclosed. One or more working electrodes may be combined with two or more counter electrodes. The two or more counter electrodes may operate at different potentials to provide for multi-analyte electrochemical analysis. Analysis methods are provided to perform multi-analyte electrochemical analysis and test sensors are provided having resistance to chemical mixing between secondary analysis regions.
