Abstract
A calibration strip for use with a package of test strips includes a substrate with and a permutative grey scale calibration pattern disposed on a surface of the substrate with the permutative grey scale calibration pattern including more than one grey scale region. Moreover, the grey scale regions of the calibration strip define a grey scale permutation that uniquely corresponds to a calibration code of test strips in a package associated with the calibration strip.
