1. A biosensor system, for determining an analyte concentration in a sample, comprising:
a test sensor having a sample interface, a temperature sensor, and a reservoir, the sample interface operable to measure an analytic output signal responsive to applying an electrical input signal to the sample housed in the reservoir and the temperature sensor operable to measure a temperature of the sample housed in the reservoir; and
one or more computer-readable media comprising computer-executable instructions that, when executed by at least one processor, perform a method for determining the analyte concentration in the sample, comprising:
generating and transmitting the electrical input signal;
applying, by one or more electrodes of the sample interface, the electrical input signal to the sample housed in the reservoir;
measuring and transmitting, by the sample interface, the analytic output signal responsive to applying the electrical input signal to the sample;
measuring, by the temperature sensor, the temperature of the sample housed in the reservoir;
conducting a primary compensation, such that at least 50% of a total error in the analytic output signal is compensated;
conducting a first residual compensation, such that at least 5% of the total error in the analytic output signal is compensated; and
determining a compensated analytic output signal based on the temperature, the primary compensation, the first residual compensation, and the analytic output signal, wherein the compensated analytic output signal corresponds to the analyte concentration in the sample.
