Medicine? There's an app for that

Pocket diagnostics are on the way thanks to the development at Cambridge University of an app that makes any smart phone a medical marvel. The app uses the smart phone's inbuilt camera to scan familiar color-change test strips commonly used to test for problems in diabetes, kidney disease, and urinary tract infection. The app makes it easier for both patients and doctors to determine the degree of color change in such tests and given connectivity to transmit appropriate medical data from patients directly to health professionals in remote regions. The app might be useful in monitoring, and thus helping to control, the spread of pandemics in the developing world.
