Researchers at Cornell University in the United States have created a smartphone app that measures blood cholesterol content. The device, which works coupled to the camera can help people who need to monitor their cholesterol level frequently. Besides simple and inexpensive, the result is faster than a conventional blood test.
The project called smartCARD (from Cholesterol Application for Rapid Diagnostics smartphone) and led by Professor David Erickson, along with two university students, all engineers. As both students Matthew Mancuso and Vlad Oncescu explain in their article on the university's website, just stick a finger with a needle and put a drop of blood on the test strip. The reagent strip separates blood components and on the other hand, the color of the strip changes according to the cholesterol level present. After that, the application analyzes the colors of the strip image that is captured by the camera and the result appears in a few seconds.
