FDA Clears First Wearable That Tracks Ketones and Glucose Together

FDA authorizes first wearable device that monitors ketone and blood sugar levels

The FDA has authorized the Libre Duo 10 Day, the first wearable device in the U.S. to continuously monitor ketone levels and the first in the world to track both ketones and glucose in a single device. Designed for people with diabetes aged 2 and older, it sends real-time readings and alerts to a smartphone, helping detect rising ketones before diabetic ketoacidosis becomes an emergency. The approval is based on six clinical studies with over 600 participants.
