Diagnosing diabetes mellitus from smartphone-based vascular signals

A need exists for rapid, cheap and noninvasive diagnostic tests for type 2 diabetes mellitus (T2DM). Now, a smartphone-based photoplethysmography screening test has been reported to detect T2DM based on a novel digital vascular biomarker, distinct from blood glucose, analysed with deep learning.
