Abstract
The present invention is directed to an improved meter that utilizes a method of reducing the effects of interfering compounds in the measurement of analytes and more particularly to a method of reducing the effects of interfering compounds in a system wherein the test strip utilizes two or more working electrodes. In one embodiment of the present invention, a meter is described which applies a first potential to a first working electrode and a second potential, having the same polarity but a greater magnitude than the first potential, is applied to a second working electrode. The meter then measures the generated current and utilizes a predetermined algorithm to correct the measured current to compensate for the presence of interfering compounds in the sample.
