Abstract
Methods of estimating the temperature of a reaction site on a measurement strip in a blood glucose measuring devices are provided. In one embodiment, a method includes determining an activation initiation time, an activation duration time, a thermal magnitude and a temperature elevation for heat generating components within a device. The temperature elevation for each of the heat generating components is determined at least in part by an impulse response matrix [Xi], the activation initiation time, the activation duration time and the thermal magnitude for each of the heat generating components. The method further includes determining a total temperature elevation of the glucose measuring device by summing the temperature elevation of each of the heat generating components, reading a temperature value provided by the temperature measuring element, and determining a reaction site temperature estimation by subtracting the total temperature elevation from the temperature value provided by the temperature measuring element.
