Thanks, BitWizrd. Great post! I wish I understood it all. I will have to think about this one. The web site has some great info and links.

Hello, I'm not sure I understand your claims about NTEG's platform. Please bear with me as I try to understand your point as it has been a long time since those science labs. Your claim, as it seems to be put, is that the NTEG platform suffers irreparably because near-infrared (NIR) spectroscopic technologies cannot adequately measure glucose. Let's suppose that is so. How does that affect NTEG's Lifeguide monitor? Well, as far as I can see, not at all. The NTEG system is based on research indicating that ISF (interstitial fluid) glucose levels correlate closely with blood glucose levels. The Lifeguide meter draws an ISF sample (using a patented procedure). That sample, which is approximately 1/100th of a drop is then analyzed for glucose levels using a signal from the FAR-INFRARED wavelengths. NTEG's claim is that the infrared energy which is transmitted through the ISF sample (hence, the analyte, which, in this case is glucose) -- which has been removed from the body -- produces a signal because glucose, like many analytes, has one waveband region in the infrared spectrum which it absorbs most strongly. For glucose, the FAR-INFRARED waveband region is the primary absorbing region, and it is for this reason that NTEG's monitor is geared to spectroscopic technology in the far-infrared waveband. (Non-invasive measurements would not work for this waveband because it is also strongly absorbed by the water prevalent in body tissues. Now perhaps I have misunderstood your point, said something scientifically inaccurate, or have misrepresented your argument. If so, please correct me. In any case, I thank you for pointing me to a NTEG competitor of which I was not aware. Regards, Steve
