The FDA says it has not authorized, cleared or approved a smartwatch or smart ring intended to measure or estimate blood glucose on its own without piercing the skin. A wearable that displays data from a separate glucose device is a different product arrangement. Ask your doctor which device is appropriate for your care.
The FDA’s safety communication says it has not authorized, cleared or approved a smartwatch or smart ring that measures or estimates glucose on its own without piercing the skin. The FDA distinguishes these products from a watch or app that displays data from a separate glucose-monitoring device.
Product claim check
| Product description | What to check |
|---|---|
| Ring claims to measure glucose by itself | FDA says it has not authorized, cleared or approved such rings for this purpose |
| App shows readings from another monitor | Confirm the separate monitor and exact app connection with their makers |
| Listing says registered or listed with FDA | Check whether the claim concerns registration, clearance, approval or authorization |
| Product is marketed for diabetes care | Ask your doctor about an appropriate device for your care |
Check the exact product
- Read the full feature description and identify what device actually senses glucose.
- Separate an independent measurement claim from a display or app connection claim.
- Look up the stated intended use and device record; a company registration statement alone is not a clearance claim.
- Ask the device maker whether its product is intended to measure glucose or only show data from another device.
- Ask your doctor or care team about glucose devices for your health needs.
