Health-e-Solutions-Evaluate-Square-Far Infrared LightA new method of measuring blood glucose using far infrared light makes i fingertip sticks unnecessary. Painful blood glucose measurement may no longer be required. Researchers say that it is entirely harmless and non-invasive.

A group of researchers, led by Prof. Yuji Matsuura of Tohoku University’s Graduate School of Biomedical Engineering, has developed a method of measuring blood glucose using far infrared light, which is both harmless and non-invasive.

Diabetes patients traditionally monitor their daily blood glucose levels by using a conventional meter which requires blood sampling from the finger tips. The discomfort of pain and risk of infection can sometimes be a source of great stress and concern.

To address that, other researchers have proposed and developed non-invasive methods for glucose measurement using near infrared light. This method works on the premise that near infrared light of some specific wavelengths are selectively absorbed by glucose in the blood.

However, accurate and stable measurement using this method has proven difficult because the near infrared light is not only weakly absorbed by glucose, but also by water, protein and hemoglobin.

In contrast, far infrared light with wavelengths of around 10 micron is strongly absorbed by glucose, making it possible, in theory, for patients to get more sensitive and accurate measurements. However, the problem faced by researchers, is that far-infrared light penetrates only a few microns from the skin’s surface, which makes the detection of blood glucose difficult.

Prof. Matsuura’s team has thus developed a new measurement technique that consists of a small prism attached to the ends of flexible hollow-optical fibers to radiate far infrared light. By using this method, it is possible to irradiate the oral mucosa of inner lips that, unlike skin, have no thick horny layer.

Results from experiments show blood glucose levels sensitively detected and accurately measured with a less than 20% margin of error, which Prof. Matsuura believes is good enough for clinical uses.

Diabetes is a serious problem that affects millions of people worldwide. By combining the new method with far infrared lasers that have recently been developed, Prof. Matsuura expects compact and low-cost blood glucose measurement systems to soon be widely used in clinical fields.

Health-e-Solutions comment: I love the fact that it does away with lancets, and perhaps thse costly test strips too, but a 20% margin of error can be the different between normal blood sugars and hypoglycemia! I hope they get it more accurate.

Health-e-Solutions- Evaluate Results-Far Infrared LightMapping, monitoring and measuring are a continuous cycle when living with diabetes. You begin with a certain course of treatment in mind, which you mapped out with the help of your medical professional. You monitor your progress and measure it against your goals. Upon evaluation, you may find a new course must be corrected to compensate for successes and challenges. Evaluating progress and results of the Health-e-Solutions lifestyle is essential to #MasterDiabetes in the healthiest way possible. This downloadable e-publication equips you with the key evaluation tools you need, along with some of the research behind them, to determine where you want to go and how to get there. We give you important tools to help you chart your course and stay on track to reach your destination.
