Procedures involved in Non-Invasive Blood Glucose Monitoring Devices

Published Date : July 31, 2017

Diabetes and the complexities that come with it enforce irreversible impact on patients and their families financially as well as emotionally. Various studies suggest that enhanced control and management of glucose has decreased long-term complexities caused by diabetes. A study from the American Diabetes Association (ADA) claims that patients who make the use of devices to monitor blood glucose by themselves; there has been a remarkable improvement in these patients along with adequate insulin, oral medications and nutrients. Furthermore, self-monitoring blood glucose (SMBG) is helpful in getting information about the impacts of the patient’s habit, food intake and physical exercise and helps to achieve certain goals that are an important part of the treatment. People with type 2 diabetes tend to lose track while making the use of self-monitoring blood glucose device for the expenses, pain and inconveniences caused by it. However, accessibility of precise, easy in operating and painless devices assist to monitor blood glucose regularly resulting in improved glucose control and reducing long-term complexities and its costs. 

Procedures that are noninvasive measure the glucose in the blood without pricking the skin, drawing blood or causing any kind of pain. A product had been allowed by the Food and Drug Administration that drew the glucose out of the skin electrically, however, it was no longer in use after a short time due to inadequate performance and causing damage to the skin of users. Various companies have made several attempts to find a long-term solution. Various methods that have been tried are transdermal measurement which is a procedure to extract the glucose through the skin by making the use of chemicals, ultrasound or electricity; near infrared spectroscopy which is a procedure to measure the glucose in body by making the use of light with wavelengths that are slightly higher than normal. A study conducted in the year of 2012 tested a number of technologies for monitoring glucose. However, those technologies gave no clinical reliability. The tested technologies included fluorescence technology, near infrared spectroscopy, bio-impedance spectroscopy, ultrasound technology, electromagnetic sensing, Raman spectroscopy, optical coherence tomography, reverse iontophoresis, optical polarimetry and mid-infrared spectroscopy.

The major issue with noninvasive devices that are used to monitor blood glucose is accomplishing precise results even though no blood is included in the process. A procedure based on various properties that is being measured generates individual reading therefore improving the validity of the results. GlucoTrack is a device that makes the use of three different techniques that are thermal, electromagnet and ultrasonic by combining them in order to get real-time and accurate measurements.
