Introducing the Libre DUO 10 Day system.
The world’s first dual glucose ketone sensor|| is coming soon.
The U.S. Food and Drug Administration (FDA) has authorized the Libre DUO 10 Day system. Soon, you’ll be able to see your glucose and ketone readings from one sensor.
What is DKA?
Diabetic ketoacidosis (DKA) is a serious, life-threatening condition2. It can develop when your body doesn’t have enough insulin, causing ketones to build up to dangerous levels2.
Why DKA can be hard to recognize
Glucose and ketone levels don’t always trend in the same direction3.
Ketones can be high even when your glucose looks normal.
Symptoms can look like the flu2.
Early signs of DKA can be easy to mistake for another illness.
DKA can develop quickly4.
Without timely action, rising ketones can quickly progress to DKA.

A study was conducted to evaluate the Libre DUO 10 Day sensor wear duration. Results showed that 84.1% of sensors in the adult population and 68.8% of sensors in the pediatric population lasted the full 10 days. This means that, when the product is used according to the labeling, approximately 16% of sensors in the adult population and 31% of sensors in the pediatric population may not last for the full 10 days.
* The Libre DUO 10 Day system does more compared to continuous glucose monitoring and traditional ketone testing (urine ketone monitoring, blood ketone monitoring).
† Based on ketone alerts and readings.
‡ The Libre app is only compatible with certain mobile devices and operating systems. Please check the Support section of our website for more information about device compatibility before using the apps. Use of the Libre app may require registration with LibreView.
§ Alarm notifications will only be received when alarms settings are enabled and turned on and sensor is within 33 feet unobstructed of the reading device.
|| Based on current public available information.

Important Safety Information
Failure to use the Libre Duo 10 Day system as instructed in labeling may result in missing a severe glucose and/or ketones event and/or making a treatment decision, resulting in injury. If readings and alarms (if enabled) do not match symptoms or expectations, use a fingerstick glucose value from a blood glucose meter for treatment decisions. Ketone output should be used in conjunction with glucose levels. The Urgent Low Glucose alarm and Urgent High Ketones alarm may not detect all instances of glucose less than 55 mg/dL and ketones higher than 3.0 mmol/L, so these should be used together with respective sensor readings for treatment decisions. Get medical attention when appropriate. For more information call Abbott Customer Service at 855-632-8658.
