  • Two electrodes functioning as three electrodes in the fluid chamber of a test strip
    Patent number: 10920259
    Abstract: An improved disposable electrochemical test sensor designed to facilitate reducing volume of fluid samples. It has a short fluid chamber having two electrodes that functions as three electrodes (one working electrode, one reference electrode and one blank electrode). The chamber provides a reservoir from which a sample fluid can be quickly drawn into the chamber through capillary action. The novel potential reverse and curve-fitting technology of the test sensor provided by the present invention can effectively eliminate most common interferents existing in the fluid samples.
