Abbott's Libre Duo Becomes First Sensor Tracking Glucose and Ketones Together
Libre Duo reads glucose and ketones every minute from fluid under the skin, cleared for insulin users as young as 2.
- Sensor wears up to 10 days, cleared for insulin users with type 1 or 2 diabetes.
- FDA used its De Novo pathway with breakthrough-device status, a fast track reserved for few products.
- Untreated ketone buildup causes diabetic ketoacidosis, which the FDA says can turn life-threatening quickly.
Why it matters: Continuous does not mean infallible: the alarm can miss the exact spike that turns diabetes into an emergency.
