When I first read about an app that detects diabetes, I must admit that I was skeptical. The app, Azumio Instant Heart Rate, uses smartphone based photoplethysmography (PPG) to detect diabetes. The contact PPG (using fingertip scan) was used to obtain waveforms of color changes in blood vessels with heart beat to develop the screening test. Further research is being conducted to see how PPG signal detected diabetes compares with diabetes detected from blood glucose or hemoglobin A1c. The app is a screening not diagnosis tool so healthcare provider would need to confirm the findings. To learn more about this interesting app, please click below.
