Online published on 29 April, 2017. Abstract Diabetes is a major health care melancholy issue of contemporary era. In order to control the blood glucose levels and to improve the quality of life, some painless diagnosing method has to be identified, thereby avoiding the complications of present day lancet methods. Although many efforts have been taken by researchers in order to successfully launch a device that measures blood glucose noninvasively, the results seems to be intruded due to the fact that designers mostly concentrate on optical methods which suffer from greater interferences due to the less absorbing property of glucose. Our earlier work investigated a possible method of measuring the Non Invasive Blood Glucose Concentration level (NI-BGC), although results achieved were quite hopeful, it needs further extensive testing and improvement in the design before it can be considered for clinical use. This paper rationalizes a method of using Ultra Violet-Visible Light (UV-VIS) Spectrophotometer for selecting the correct Light Source of proper wavelength, by testing the raw blood sample and artificial Glucose samples-to be employed in the design. This work also draws together readings from two different sensors based on absorption photometry and by averaging the sensor values using embedded technology; a non-invasive glucometer has been modelled to provide a boon for the person hankering to diagnose diabetes.
