A method of deriving correction for instrument-to-instrument variations in the illumination band centroid wavelengths and wavelength band shapes of the optical systems of clinical chemistry instruments includes the steps of determining the centroid wavelength and wavelength band shape of a light source used in the optical system of a clinical chemistry instrument to provide a determined wavelength band shape and centroid wavelength, comparing the determined wavelength band shape and centroid wavelength with a known reflection density or absorbance wavelength spectrum of a specific type of chemical reagent test to provide a correction value, and calculating the correction value, which is to be used to modify a reflection density or absorbance measurement taken by the instrument of a reagent test of the a specific type of chemical reagent test.
