Abstract:
A method for correcting ambient temperature effect in biosensors comprising the steps of:measuring an ambient temperature value; applying a sample to the biosensors and measuring a current generated in the test sample; calculating an analyte concentration value utilizing said measured ambient temperature value to thereby increase the accuracy of the analyte determination; and said step of calculating said analyte concentration value includes the step of converting said measured current to an observed analyte concentration value and calculating a corrected analyte concentration value utilizing the equation: G2=G1-(T22-242)*I2-(T2-24)*I1(T22-242)*S2+(T2-24)*S1+1â€ƒwhere G1 is said observed analyte concentration value, T2 is said measured ambient temperature value and I1, I2, S1, and S2 are set values and are experimentally determined coefficients.
