Abstract
Described and illustrated herein are exemplary methods of operating an analyte measurement system having a meter and a test strip. Such methods may be exemplarily achieved by determining a first glucose concentration by measuring a first reflectance at about a first wavelength at a testing surface of the pad; measuring a second reflectance at about a second wavelength; formulating at least one equation to correct the first glucose concentration for temperature or hematocrit effects using the second reflectance at about the second wavelength; determining a second glucose concentration using the first glucose concentration, the second reflectance at about a second wavelength; and displaying the second glucose concentration that is corrected for temperature and hematocrit effects.
