• First-of-its-kind biowearables combine continuous glucose and ketone monitoring in a single sensor to support both daily diabetes management and help detect rising ketone levels that can lead to diabetic ketoacidosis, a serious health condition for people with diabetes
• Integrates with the Libre digital health ecosystem, allowing people to share glucose and ketone data with caregivers and healthcare providers
• Designed for compatibility with leading automated insulin delivery (AID) systems

ABBOTT PARK, Ill., May 27, 2026 /PRNewswire/ — Abbott (NYSE: ABT), a global healthcare leader, announced today it has secured CE Mark for the world’s first dual glucose‑ketone sensing technology for people with diabetes. Branded as Libre Duo and Libre Duo 10 Day, the systems are designed to continuously measure glucose and ketone levels every minute, providing real-time visibility into both glucose levels needed for daily diabetes management as well as rising ketones that can lead to a diabetic ketoacidosis (DKA) emergency. This marks the first time people with diabetes will be able to monitor ketones without traditional blood or urine tests. Abbott plans to begin launching Libre Duo systems in select European countries later this year.

Why monitoring ketones matters for people with diabetes
In people with diabetes, DKA develops when the body does not have enough insulin and begins breaking down fat for energy, causing ketones to rise to dangerous levels in the blood.¹ According to the American Diabetes Association, elevated ketones can escalate to DKA within hours and, if left untreated, can lead to coma or death.¹ Yet, despite clinical guidance recommending ketone testing during illness or periods of elevated glucose, early detection remains a persistent challenge.

How Libre Duo systems work
Libre Duo systems continuously monitor both glucose and ketone levels, reducing reliance on blood or urine tests that capture only a single moment in time. The sensors are designed to help people with diabetes monitor glucose levels – the standard of care for daily diabetes management – while also alerting people to rising ketones so they can act sooner and potentially avoid a serious DKA emergency.

This CE Mark covers two Libre Duo systems. Libre Duo delivers up to 15 days of wear and will be offered to adults ages 18 and older. Libre Duo 10 Day offers up to 10 days of wear and is intended for people ages 2 and older. Clinical data indicate that a 10-day sensor can help active youth complete the full wear period. Both sensors deliver consistent, strong accuracy.

Libre Duo systems will integrate with Abbott’s Libre digital health ecosystem, enabling users to share glucose and ketone data with caregivers and healthcare providers. Abbott is also working with leading pump companies to allow automated insulin delivery (AID) systems to connect with the sensors.

“Abbott has a long-established pattern of setting the pace in health tech innovation,” said Chris Scoggins, executive vice president of Abbott’s diabetes care business. “People living with diabetes routinely tell us that the risk of serious complications is a constant part of everyday life. Our Libre Duo systems offer people with diabetes, families and healthcare providers clearer, earlier information about what’s happening inside their body, allowing them to act sooner when safety matters most.”

Libre Duo systems align with recommendations outlined in a recent international expert consensus paper from Breakthrough T1D, a global organization focused on Type 1 diabetes research and advocacy, which describes the safe and effective use of continuous ketone monitoring as part of diabetes management. ²

A growing gap in diabetes care
DKA can develop quickly and is often difficult to detect early. Because ketones are not routinely monitored, warning signs are frequently missed, contributing to delayed intervention and rising rates of DKA. Recent data illustrate the scale of these challenges:

• Glucose and ketones don’t always rise together: Ketones can rise independently of glucose levels and, in some cases, even when glucose appears in range – which can delay detection of diabetic ketoacidosis (DKA) risk.²
• DKA rates are rising: According to research published in the peer-reviewed journal, Diabetes Care, hospital admissions for DKA have increased approximately 55% over the past decade, and the U.S. Centers for Disease Control and Prevention (CDC) lists DKA as a leading cause of death among children and adults under age 58 with Type 1 diabetes.³ A recent analysis of nearly 660,000 people in the United Kingdom, conducted by leading diabetes researchers and presented at the 2026 Conference for Advanced Technologies & Treatments for Diabetes (ATTD), found that DKA rates are increasing among people with both Type 1 and Type 2 diabetes, with a high risk of recurrence. Over the 23-year study period, DKA incidence in adults with Type 1 diabetes more than tripled, while incidence among people with Type 2 diabetes increased sixfold.⁴
• DKA leads to more hospitalizations than hypoglycemia: According to the CDC, DKA accounts for approximately four times more hospitalizations than hypoglycemia, making it the dominant driver of acute diabetes-related healthcare utilization in the U.S.^[5]
• Symptoms are often missed: Early signs of rising ketones, such as nausea, fatigue or flu‑like illness, are frequently mistaken for common infections, delaying recognition and treatment.^2,6,7
• Ketone monitoring remains limited: In a survey of nearly 3,000 people with Type 1 diabetes published in the peer-reviewed journal, Diabetes Care, only 18% reported having a blood ketone meter at home, while nearly one‑third reported having no ketone testing supplies – blood meters or urine strips – at all.⁸

Libre Duo systems are not yet cleared or available for sale in the United States.

Frequently Asked Questions

What is Libre Duo?
Libre Duo systems are two-in-one biowearables that provide real-time visibility into both glucose levels and ketones. Early detection of rising ketones may help people avoid a serious diabetic ketoacidosis (DKA) emergency.¹

Who should use Libre Duo?
Libre Duo systems are designed for people with diabetes with higher risk for DKA, including people with Type 1 or Type 2 diabetes who use insulin or other glucose-lowering medications, such as sodium-glucose cotransporter 2 inhibitors, also known as SGLT2s.

Do people with diabetes need a continuous ketone monitor?
Continuous glucose monitors (CGMs) track glucose, but they do not measure ketones. According to the American Diabetes Association, elevated ketones can progress to DKA within hours, making early detection critical. Because ketone levels can rise quickly — sometimes independently of glucose — and symptoms are often mistaken for common illnesses, having visibility into ketone trends may help people better understand when they could be at risk and take action sooner.^1,2,4,6
