Claim:
A method for measuring a temperature corrected glucose concentration over a temperature range, the method comprising the steps of: applying in a test meter a first test voltage for a first time between a first electrode and a second electrode in communication with a sample disposed on a test strip within the test meter, the first time interval being sufficient to oxidize a reduced mediator at the second electrode; following the application of the first test voltage, applying a second test voltage for a second time interval between the first electrode and the second electrode sufficient to oxidize the reduced mediator at the first electrode; calculating a first glucose concentration based on test current values during the first time interval and the second time interval; measuring a temperature value using a temperature reading device incorporated into the test meter that receives the test strip; and calculating a temperature corrected glucose concentration based on the first glucose concentration and the temperature value, wherein the step of calculating the temperature corrected concentration includes the additional steps of: calculating a correction value based on the temperature value and the first glucose concentration; and calculating a temperature corrected concentration based on the first glucose concentration and the correction value, wherein the correction value is calculated with a first function if the temperature value is greater than a first temperature threshold, and wherein the correction value is calculated with a second function if the temperature value is not greater than a first temperature threshold, and in which the first function is a first equation, the first equation being: Corr 2 =−K 1 ( T−T RT )+ K 2 ×G 1 ( T−T RT ) Where Corr 2 is the correction value, K 1 is a first constant, T is a temperature value, T RT is a room temperature value, K 2 is a second constant and G 1 is the first glucose concentration.
