- Garmin filed a patent in May called "Pressure compensation for wrist-based pulse spectrometry" to track users' "glycated hemoglobin level" via smartwatch.
- A Garmin watch would track your HbAlc, or amount of glucose attached to blood cells across a long period, non-invasively.
- The patent mentions other trackable "blood content" like COHb, MHb, SHb, O2Hb, and others using the optical PPG sensor.
- Garmin watches can currently display continuous data from Dexcom blood glucose monitors.
