Abbott’s Libre Duo systems are the world's first dual glucose-ketone sensing biowearables for people with diabetes. The systems continuously monitor both glucose and ketone levels through a single wearable sensor, helping people manage glucose levels for daily diabetes care while also detecting rising ketones before they progress to a diabetic ketoacidosis (DKA) emergency. By reducing reliance on traditional blood or urine ketone tests that provide only a point-in-time measurement, Libre Duo systems deliver earlier awareness and actionable insights when they matter most. Available in 10-day and 15-day wear options, the systems integrate with Abbott's Libre digital health ecosystem, enabling users to share glucose and ketone data with caregivers and healthcare providers while supporting connectivity with automated insulin delivery systems.
