FDA Authorizes Abbott Libre Duo Dual Glucose and Ketone Sensor

FDA authorizes Abbott $ABT Libre Duo, the world's first single wearable monitoring both ketones and blood sugar. The sensor measures both metrics every minute in fluid beneath the skin over a 10-day wear period. Authorization relied on data from six clinical studies involving over 600 participants aged two and older. Readings stream wirelessly to smartphones to issue real-time alerts for rising ketone levels. The system targets an estimated 2.1 million Americans living with type 1 diabetes who face DKA risks. "Knowing that ketone levels are rising, and having that information in real time, around the clock, can be the difference between early intervention and a life-threatening emergency." — Michelle Tarver Adding continuous ketone tracking to standard glucose monitors sets a new baseline legacy single-metric sensors won't compete with.
