Testing your blood glucose levels if you're a diabetes sufferer may not mean hauling around largeish devices now that the True2Go from Home Diagnostics has won FDA approval. It's the world's smallest, "about the size of a quarter"... it's just about the same size as an iPod shuffle. It's small enough to twist "on to a vial of test strips so diabetics can better manage their diabetes with the convenience of on-the-go testing," which is darn convenient, and it uses 0.5 microliters of blood and has a test memory display. No word on pricing or release timings yet. [Medgadget]
