The company said its dual sensor marks a world first, continuously measuring glucose and ketone levels every minute. Branded as Libre Duo and Libre Duo 10 Day, the sensors provide real-time visibility into glucose levels as a standard CGM like Abbott’s FreeStyle Libre system does, but also into rising ketones that can lead to a diabetic ketoacidosis (DKA) emergency.

Abbott said this clearance marks the first time people with diabetes can monitor ketones without traditional blood or urine tests. It plans to begin the rollout of its Libre Duo systems in select European countries later this year.
