FDA warns against unauthorized blood glucose measuring wearables

The FDA warns against smartwatches and smart rings claiming to measure blood glucose levels, as none are authorized for this purpose. Major wearables only support FDA-authorized continuous glucose monitors. Scammy devices making unsubstantiated claims are targeted. Misleading companies sell these devices at trade shows and online. The FDA urges reporting such devices. Reputable wearable brands are not capable of measuring blood glucose. Progress in the wearable space is promising but not ready for healthcare settings or consumers.
