Claim One:
1. An analyte test sensor, comprising: at least two substrates in the form of a base and a lid combined to form a reservoir, the reservoir having a primary area between eight secondary analysis regions, the eight secondary analysis regions including a first region, a second region, a third region, a fourth region, a fifth region, a sixth region, a seventh region, and an eight region, the eight secondary analysis regions being distinct, separate, and structurally isolated to resist or eliminate diffusive or convective mixing of reagents between the secondary analysis regions during one or more analyses of a sample, the primary area having a sample port where sample introduction occurs into the test sensor; four working electrodes including a first working electrode, a second working electrode, a third working electrode, and a fourth working electrode, the four working electrodes being distinct and separate, each of the working electrodes including a first conductor and a reagent composition, each of the reagent compositions having a different redox potential; and four counter electrodes including a first counter electrode, a second counter electrode, a third counter electrode, and a fourth counter electrode, the four counter electrodes being distinct and separate, each of the counter electrodes including a second conductor and at least one redox species, wherein each of the four working electrodes and the four counter electrodes is disposed in a respective separate one of the eight secondary analysis regions such that the first region has the first working electrode and its respective first conductor and reagent composition, the second region has the second working electrode and its respective first conductor and reagent composition, the third region has the third working electrode and its respective first conductor and reagent composition, the fourth region has the fourth working electrode and its respective first conductor and reagent composition, the fifth region has the first counter electrode and its respective second conductor and at least one redox species, the sixth region has the second counter electrode and its respective second conductor and at least one redox species, the seventh region has the third counter electrode and its respective second conductor and at least one redox species, and the eighth region has the fourth counter electrode and its respective second conductor and at least one redox species; wherein the first conductors of the working electrodes are electrically connected; and wherein the second conductors of the counter electrodes are not electrically connected.
