[February 22, 2024]
(Reuters) -The U.S. Food and Drug Administration warned consumers
on Wednesday against using smartwatches or smart rings that claim to
measure blood glucose levels without piercing the skin, regardless of
manufacturer or brand.
The health regulator said it was working to ensure that manufacturers,
distributors and sellers do not illegally market unauthorized gadgets
that claim to measure blood glucose levels.
The devices are different from smartwatch applications that display data
from FDA-authorized blood glucose measuring devices that puncture the
skin, the regulator said.
The agency said it had not authorized, cleared, or approved any
smartwatch or smart ring intended to measure or estimate blood glucose
values on its own, nor evaluated their safety or effectiveness.
Such devices are manufactured by dozens of companies and sold under
multiple brand names. Their makers often claim the gadgets can measure
blood glucose levels without requiring users to prick their skin.

Inaccurate blood glucose readings
can lead to errors in diabetes management, including taking the
wrong dose of insulin or other medications that rapidly lower sugar
levels, the FDA said.
