Patent ID: 7964089

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 and a counter electrode and a mediator that serves as a charge carrier in the electrochemical determination of the analyte, (b) electrochemically determining an uncorrected result for the determination of analyte in the sample; (c) determining an additive correction factor for the amount of oxygen in the sample, and (d) modifying the uncorrected result of step (b) with the correction factor of step (c) to provide a corrected determination of analyte in the sample, wherein the additive correction factor 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, wherein the sample is a blood sample, the measurement that reflects the oxygen carrying capacity is hematocrit (hct) and the additive correction factor is given by the equation additive correction factor=constant×[( S×T )+ I]×hct wherein T is the temperature, S and I are the slope and intercept, respectively, of a plot in which the y axis is the slope of a line plotting uncorrected analyte measurement as a function of hematocrit and the x axis is temperature, and constant is an empirically determined constant for the particular apparatus and method of determining hematocrit.
