1. A method of determining glucose concentration of a whole blood sample using an optical test sensor, the method comprising:

  • providing an optical test sensor including a reagent composition having an enzyme;

    measuring transmission levels at two different wavelengths of the whole blood sample;

    correcting absorbance bias of the whole blood sample, if any, caused by hematocrit levels using the transmission levels at two different wavelengths; and

    determining the glucose concentration using the measured transmission levels and corrected absorbance bias, if any, of the whole blood sample.
