Abstract: Diabetic patients need to monitor their blood glucose levels frequently to prevent complications related to the disease. Commonly used glucose measurement methods are invasive, uncomfortable, and usually require frequent finger pricking. This paper deals with the development of a non-invasive system for continuous measurement of blood glucose concentration levels, using near infrared light of suitable wavelength. Glucose determination using near infrared can be done by taking measurement of transmitted light through human body. This device may become very useful while conducting glucose tolerance test (GTT). In glucose tolerance test, patient should be given a measured dose of glucose solution to drink and blood is drawn at intervals of half an hour or one hour for two to four hours. This requires five to nine finger pricking for measurement of glucose concentration. By using this proposed device pricking can be reduced to one. First the glucose concentration is measured using conventional method for calibration. Then by comparing with the first sample measurement subsequent values can be determined without further pricking.
