GlucoScreen image 5 (IMAGE) University of Washington Caption Anandghan Waghmare, a University of Washington doctoral student in the Paul G. Allen School of Computer Science & Engineering, holds up a prototype of the GlucoScreen test strip. Waghmare and his fellow researchers modified a commercially available test strip to incorporate inexpensive circuitry that transmits data generated by the reaction between a person’s blood and enzymes on the strip to the phone via simulated tapping on the touch screen. GlucoScreen then applies machine learning to calculate a blood glucose reading on the phone and alert the user if they are at risk of prediabetes. Credit Raymond C.
