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 at top) with any smartphone — no separate glucometer required. After processing the data transmitted from the test strip, GlucoScreen displays the calculated blood glucose reading on the phone with a link to more information about what the result means. A blood glucose level between 100 and 125 mg/dL would indicate prediabetes. In this example, GlucoScreen returned a reading of 91 mg/dL, which is within the normal range.
