1. A method for determining an analyte concentration in a sample of a biological fluid, comprising:
- determining a sample temperature of the sample;
generating an output signal in response to a redox reaction of an analyte in the sample;
selecting a slope value and an intercept value from a correlation of output signals and analyte concentrations previously determined at a reference temperature;
adjusting the selected slope value and the selected intercept value in response to the sample temperature to provide an adjusted slope value and an adjusted intercept value; and
calculating an analyte concentration from the output signal and the adjusted slope and intercept values.

Abstract
A biosensor system determines analyte concentration from an output signal generated by an oxidation/reduction reaction of the analyte. The biosensor system adjusts a correlation for determining analyte concentrations from output signals at one temperature to determining analyte concentrations from output signals at other temperatures. The temperature-adjusted correlation between analyte concentrations and output signals at a reference temperature may be used to determine analyte concentrations from output signals at a sample temperature.
