A new method to detect diabetes, even before symptoms occur, is being developed by a team of endocrinologists, engineers and microbiologists. A device projects light to the skin which measures levels of blood sugar, or the presence of advanced glycation endproducts. This device is called The Scout. Different wavelengths is flashed to the skin to determine diabetes risk. This will help patients go on a preventive health maintenance program. With this method, diabetes can actually be prevented. It is already being tested in several US hospitals. The new method is expected to cost about the same as existing diabetes testing methods.
