Abstract
A method of improving the utility of electrochemical glucose sensors by decreasing either or both their settling time and their sensitivity to interfering compounds. In particular, the settling time of an electrochemical glucose sensor is improved by pretreating the operating electrode with a negative electric current at a constant current density. The sensor's sensitivity to intefering compounds is reduced by operating the sensor at a reduced voltage while the glucose concentration measurement is being made.
