Abstract:
1. A method for performing assays of a fluid using a biosensor that comprises a first electrode set including a working electrode and a counter electrode; a working electrode terminal and a first reference terminal that are connected to the working electrode; a counter electrode terminal and a second reference terminal that are connected to the counter electrode; and a second electrode set including two electrodes; wherein the second electrode set is disposed near the first electrode set; the method comprising: connecting the biosensor to a measurement circuit; performing an assay of the fluid based on a current flowing through the working electrode terminal or the counter electrode terminal; controlling a voltage between the working electrode and the counter electrode using a voltage detected by the first reference terminal and a voltage detected by the second reference terminal; and performing another assay of the fluid based on a current flowing between the two electrodes of the second electrode set.
