To correct the baseline drifts  In the paper  the fingertips spectra in mid-infrared were recorded under the special conditions. A line equation was calculated using the last 14 spectra coupled with the linear regression analysis between the absorbance spectra at the 1035cm-1 and the 950cm-1. And the corrected absorption intensities  after the removal of the baseline drifts  can be applied for the quantification of glucose concentrations in blood easily with the given method in the paper.
