Patent ID: 8361307

Claim:
A method for determining an analyte in a sample comprising the steps of: (a) placing the sample in an electrochemical test cell comprising a working electrode and a counter electrode and a mediator that serves in reduced form as a charge carrier in the electrochemical determination of the analyte, wherein the sample is subject to oxygen attrition in the electrochemical test cell, (b) applying a DC signal between the working and counter electrodes to produce a DC output signal, (c) evaluating the DC output signal to determine an uncorrected result for the determination of analyte in the sample; (d) determining an additive correction term for the amount of oxygen in the sample, said additive correction term being independent of pO 2 and glucose concentration in the sample, and (e) adding the correction term of step (d) to the uncorrected result of step (c) to provide a corrected determination of analyte in the sample, wherein the additive correction term for the amount of oxygen in the sample is determined as a function of the temperature of the sample and a measurement that reflects the oxygen carrying capacity of the sample.
