Diabetes Mellitus, a disorder that reduces the body’s ability to maintain normal blood glucose levels, has been threatening the world since many decades. Glucose, being one of the most important compound that in vital for the human body, should be maintained in correct levels. The right blood glucose level is important as it provides different parts of the body with energy to function properly. Diabetics must hence know their blood glucose levels, so that they can control them with supplements like oral drugs, other treatments or calisthenics. The presently available best and recommended technique for the diagnosis and subsequent suitable treatment is the glycated hemoglobin test (or) A1C test which is a measurement of the overall control of the diabetic for the previous two to three months. Most diabetic specialists feel that it is now the single most important blood test for known diabetics. But this is currently done in an invasive manner with the extraction of blood due to which the diabetics refuse to undergo the test leading to the increase in the severity of the disorder. This paper presents a novel framework for blood glucose level measurement using a combination of the A1C test and Photo-Acoustic Spectroscopy to get a absolutely consistent and precise, non-invasive technique to enhance the spirits of the diabetics. A noteworthy facet of the in vivo system is that it could be used to measure not only the glucose levels but also the hemoglobin content, WBC counts and some other blood components. Some other prominent characteristics of this technique are that it is location independent and can also be used for anyone.
