GlucoScreen image 4 (IMAGE)
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 rectangular strip) with any smartphone — no separate glucometer required. The GlucoScreen app walks the user through each step of the testing process, which is similar to a conventional glucometer-based test. After affixing the test strip to each side of the phone, a user pricks their finger and applies a drop of blood to the biosensor attached to the strip (shown here). Once the strip transmits the data 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. Note: the blood in this photo is not real.
