Glucose is the major carbohydrate found in blood and a chief source of energy in human body. The blood glucose levels are perfectly maintained under the influence of hormones like insulin and glucagon. However, the hormonal imbalance sometimes may result in abnormalities of glucose metabolism and result in diseased condition. Thus, the detection of blood glucose levels can provide a basic understanding of the malfunctioning of the tissues and body. In the present study use of venous derived blood glucose estimation using glucometers designed for capillary blood samples enables rapid treatment decisions.
