Garmin has patented long-term blood glucose tracking; here's how it'd work

Unlike a typical blood glucose monitor, this patented non-invasive system would use pulse spectrometry to track your long-term HbA1c.

Garmin filed a patent in May called "Pressure compensation for wrist-based pulse spectrometry" to track users' "glycated hemoglobin level" via smartwatch. Still, we're happy to see Garmin attempt to tackle this problem, with HbA1c data that'll provide early warning to prediabetics that things are getting worse or to diabetics that their efforts at getting healthy are working. Channeling his love of running, he established himself as an expert on fitness watches, testing and reviewing models from Garmin, Fitbit, Samsung, Apple, COROS, Polar, Amazfit, Suunto, and more.
