ABSTRACT:
A system for more accurately measuring glucose in a sample includes a first glucose-sensing electrode incorporating a quantity of glucose oxidase, a second glucose-sensing electrode incorporating a quantity of PQQ-glucose dehydrogenase, a reference electrode, and means for selecting between a first glucose measurement made with the first glucose-sensing electrode and a second glucose measurement made with the second glucose-sensing electrode.
