doubling as a video game. The GlucoBoy tests small amounts of blood for glucose levels, just like a normal glucose self-diagnosis device. Upon plugging it into a Game Boy Advance or DS, however, GlucoBoy rewards players for routine glucose checks or having correct blood sugar levels by giving them points, which can be used to unlock mini-games on the cartridge.
Interestingly, we originally reported about GlucoBoy way back in 2005, with Engadget having reported on it first in 2004. Due to the device's small market, its inventor Paul Wessel has spent three years trying to get approval from Nintendo to produce the device. GlucoBoy launched in Australia on World Diabetes Day, with plans to bring the glucose-testing device to more regions soon.
