GlucoScreen image 1 (IMAGE) University of Washington Caption Researchers at the University of Washington have developed GlucoScreen, a system that could enable people to self-screen for prediabetes. It uses a modified version of a commercially available test strip (white rectangle on the right) with any smartphone — no separate glucometer required. Leveraging the phone's built-in capacitive touch sensing capabilities, GlucoScreen transmits test data from the strip to the phone via a series of simulated taps on the screen. The app applies machine learning to analyze the data and calculate a blood glucose reading. With early detection, many cases of prediabetes can be reversed through changes to diet and exercise.
