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 the present invention, a meter is described which applies a first potential (E1) to a first working electrode (12) and a second potential (E2), having the same polarity but a greater magnitude than the first potential is applied to a second working electrode (14). 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.

Claims (4)

1. An improved meter for use in the detection of analytes, said meter comprising:
a first connector for connecting said meter to a first working electrode on said test strip;
a second connector for connecting said meter to a second working electrode on said test strip;
a common connector for connecting said meter to a reference electrode on said test strip;
a first voltage source connected between said first connector and said common connector;
a second voltage source connected between said second connector and said common connector.
2. An improved meter according to Claim 1 wherein said first and second voltage sources generate a first potential at said first connector and a second potential said second connector when a test strip is inserted into said meter and a sample is applied to said test strip, wherein said first and second voltages have the same polarity and said second potential has a magnitude greater than said first potential.
3. An improved meter according to Claim 2 wherein said meter measures a first current value at said first connector and a second current value at said second connector at a predetermined time after said test strip is inserted and sample applied.
4. An improved meter according to Claim 3 wherein said meter calculates a corrected value of analyte current using the following formula:
where: A1 is said corrected analyte current; W1 is the current at said first connector measured at said predetermined time; W2 is the current measured at said second connector at said predetermined time; X is an analyte dependent voltage effect factor;
and Y is an interfering compound dependent voltage effect factor.
