Abstract: Colorimeters have been used in the Clinical Laboratories for estimating the concentration of Blood Glucose of the Diabetic patients for the past 5 decades. The complex substances appearing in Blood serum develop color following the reaction with a reagent. Colorimeter measures the concentration of the Blood substance based on the amount of absorption of a monochromatic light in that solution. Error of 5-20% is not uncommon because those measurements require a highly monochromatic source. The spectral bandwidth of the filters used for this purpose and the operational wavelength of the photo detector are also behind the inaccuracy in the result. This paper addresses Digital Image Processing technique as a complementary and alternative method of Glucose measurement. The performance of measurement of Blood Glucose based on the RGB data of Colour Image of the assay is compared with that of the Colorimeter. The results show the consistent performance of Digital Image Processing even in the non-linear region of the assay.
