All you need is a smartphone and a little piece of paper to have a game-changing impact on diabetes. Approximately 1.5 to 2 billion people in the world suffer from diabetes, pre-diabetes, or a complication associated with it, and yet more than 90% of them never even get tested. To combat this challenge, Professor Tarun Khanna developed a simple diagnostic device that works with any smartphone in the world. The result is a game-changing innovation that is reshaping the state of diabetes testing, treatment, and data analysis around the globe.
