Abbott FreeStyle Libre 3 Sensor Recall Leads to Lawsuits & Settlement Claims

March 12, 2026 — A Class 1 Recall, the most serious FDA recall is now in effect for FreeStyle Libre 3 Sensor’s for incorrect readings.

The FreeStyle Libre 3 sensor faces a Class I recall (and lawsuits) the most severe designation issued by the FDA. Abbott’s popular continuous glucose monitoring device has produced incorrect readings that resulted in serious injuries and deaths worldwide. The manufacturing defect affects specific sensor models, prompting urgent action from diabetes patients and healthcare providers. This recall highlights critical safety concerns about device accuracy and the potentially life-threatening consequences of faulty glucose measurements. Patients using these sensors must verify their devices immediately and understand alternative monitoring methods to maintain safe blood sugar management.

March 12, 2026 –NBCNEWS.com Story Highlights one persons story of the failed FreeStyle Libre 3 Sensors incorrect readings: Michael Ford managed his Type 2 diabetes with help from his son Davonte, his full-time caregiver who administered medications and monitored blood sugar levels.

One November morning, Michael’s Abbott FreeStyle Libre 3 Plus sensor showed low blood sugar. Following medical advice, Davonte gave his father fast-acting carbohydrates. Despite multiple sugary drinks and snacks, the reading stayed around 68 mg/dL. When Michael’s condition worsened, Davonte called an ambulance. Paramedics revealed Michael’s actual blood sugar was 551 mg/dL—dangerously high, not low.

Michael, 68, died the next day following cardiac arrests. Eight days later, Abbott issued an urgent warning about 3 million faulty sensors.

The Abbott recall highlighted diabetes patients’ dependence on technology and risks when it fails. It prompted three class action lawsuits and Davonte’s wrongful death suit, with three others planning legal action. Questions arose about the recall’s scope and whether injuries exceed Abbott’s count of 860. Michael’s death isn’t included despite his sensor being from recalled lots.

Abbott expressed sadness over Michael’s death, saying it investigates all adverse events. The company noted not all sensors in each lot were affected and attributed faulty readings to a production issue now fixed.

Continuous glucose monitors revolutionized diabetes care two decades ago, offering automatic blood sugar monitoring. However, “it is technology, and sadly, technology can break,” said Dr. Amy Warriner. Previous recalls affected Abbott and Dexcom devices.

Some diabetes patients say discovering flaws in life-sustaining devices is terrifying. Angela Ivery, 71, from North Carolina, visited emergency rooms multiple times after her Libre 3 showed low blood sugar, though finger sticks revealed normal levels. She developed nightmares and lasting anxiety. “I’m paranoid when I get out. I think my sugar is dropping,” she said.

Cathy Bennett, 67, from Georgia, received alerts showing blood sugar in the 60s, while finger sticks showed 170s or 180s. Her sensors weren’t listed on Abbott’s recall website.

The recall exposed confusion at hospitals. One endocrinologist discovered he’d given a patient a recalled sensor.

Philip Myers, a Marine veteran in Florida, stopped using his device after erratic readings. Six months later, he learned it was recalled. “When I was in military service, I was in control,” Myers, 80, said. Managing diabetes with an inaccurate device “feels very hopeless because you’re not in control.”

Abbott’s spokesperson said the manufacturer cares about product safety and takes action when issues arise.

Davonte Ford remembers his father as selfless, not his painful final moments. “Everything was always well — until it wasn’t.”

FDA Issues Class I Recall for FreeStyle Libre 3 Sensors

Abbott Diabetes Care issued a medical device correction for certain FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors on November 24, 2025, after internal testing revealed sensors could deliver incorrect low glucose readings [1]. The FDA classified this action as a Class I recall on February 4, 2026, marking it as the agency’s most serious designation for medical device issues [1].

What Models Are Affected

Four specific sensor models fall under this recall action. The FreeStyle Libre 3 Sensor includes model numbers 72081-01 and 72080-01, with Unique Device Identifiers 00357599818005 and 00357599819002 [1]. The FreeStyle Libre 3 Plus Sensor encompasses model numbers 78768-01 and 78769-01, carrying Unique Device Identifiers 00357599844011 and 00357599843014 [1].

Abbott traced the defect to sensors manufactured on a single production line among several facilities that produce these devices [1]. No other FreeStyle Libre family sensors, readers, or smartphone applications are impacted by this correction effort [1]. The company resolved the manufacturing issue after identifying its root cause [1].

How Many Devices Are Involved

The recall encompasses approximately 3 million Libre 3 and Libre 3 Plus sensors distributed throughout the United States from the affected production line [1]. Abbott estimates that about half of these devices have either expired or already been used by patients [1]. While this may be true, the remaining sensors still in circulation or on pharmacy shelves require immediate attention from users and healthcare providers.

As of January 7, 2026, Abbott reported 860 serious injuries and seven deaths associated with this issue globally [2]. The United States accounted for 57 severe adverse events, while all seven fatalities occurred outside the country [1]. These figures represent a significant increase from earlier reports, as the FDA initially issued an Early Alert communication on December 1, 2025 [1].

Timeline of the Recall Announcement

Abbott announced the medical device correction on November 24, 2025, following the completion of internal testing that identified the sensor accuracy problem [1]. The FDA responded by issuing an Early Alert communication on December 2, 2025, to notify the public about this potentially high-risk device issue [1].

The agency published formal recall information on January 15, 2026, providing detailed guidance for patients, healthcare providers, and distributors [1]. On February 4, 2026, the FDA updated its communication to inform the public that this issue received a Class I Recall classification [1]. The FDA also modified the list of affected lots for clarity, though the affected products themselves remained unchanged [1].

Abbott has continued receiving adverse event reports throughout this period. The company documented 736 severe complications globally, with these numbers subsequently rising to 860 serious injuries as of early January 2026 [1]. This progression demonstrates the ongoing nature of the safety concern and the need for immediate patient action.

How Incorrect Glucose Readings Led to Deaths and Injuries

Sensors affected by this recall display glucose measurements lower than patients’ actual blood glucose levels. Abbott’s internal testing determined this accuracy problem after analyzing device performance data from the affected production line. The sensors fail to detect true glucose concentrations, creating a false sense of blood sugar control for people managing diabetes.

Understanding the Nature of the Defect

The malfunction produces consistently inaccurate low readings over extended periods rather than isolated errors. These falsely low measurements persist across multiple readings, preventing users from recognizing the inaccuracy through single-point verification. Accordingly, patients who rely solely on sensor data receive a distorted picture of their metabolic state. The sensors show glucose levels appear stable or low when actual blood glucose may be dangerously elevated or rapidly changing.

This pattern of incorrect readings triggers a cascade of flawed treatment decisions. Patients observing falsely low glucose measurements may consume excessive carbohydrates to raise what they believe are dropping blood sugar levels [1]. Alternatively, users may skip or delay necessary insulin doses, assuming their glucose control requires no intervention [1]. Both responses prove harmful when actual blood glucose differs significantly from sensor readings.

Global Impact: 860 Injuries and 7 Deaths Reported

The FDA documented 860 serious injuries linked to this sensor defect as of January 7, 2026 [1]. These adverse events span multiple countries where Abbott distributes the FreeStyle Libre 3 system. Seven deaths have been associated with the incorrect readings [1]. None of these fatalities occurred within the United States, though the exact countries involved remain undisclosed in official reports.

The United States accounts for 57 severe adverse events among the global total [3]. This geographic distribution suggests broader international usage patterns or potentially different regulatory reporting requirements across regions. The FDA classified this situation as a “potentially high-risk issue” in its alert communications [4]. The agency continues monitoring incoming reports as patients and healthcare providers identify additional cases potentially linked to sensor inaccuracy.

Why Low Glucose Readings Are Dangerous

Falsely low glucose readings create specific medical risks for diabetes management. When sensors indicate blood sugar appears controlled or low, patients make treatment adjustments that worsen actual hyperglycemia. Consuming extra carbohydrates in response to phantom low readings drives blood glucose higher. Skipping insulin doses eliminates the correction needed for existing elevated glucose levels.

These incorrect treatment decisions over extended periods may lead to serious health complications [1]. Prolonged hyperglycemia damages blood vessels, nerves, kidneys, and other organs. Acute complications include diabetic ketoacidosis, a life-threatening condition requiring emergency intervention. The sensor defect essentially inverts the protective function these devices serve, transforming a monitoring tool into a source of medical harm.

People with diabetes depend on accurate glucose readings to make life-sustaining decisions multiple times daily. Sensor inaccuracy undermines this foundation of diabetes self-management. The consequences range from less serious complications to potential injury or death [1]. This recall highlights the critical importance of device accuracy in chronic disease management and the severe outcomes that result when medical technology fails its core function.

What Diabetes Patients Must Do Immediately

Patients using affected sensors must take immediate action to determine device status and switch to reliable monitoring methods. Abbott sent letters to all affected customers on November 24, 2025, outlining specific verification and replacement procedures [1].

Steps to Verify If Your Sensor Is Affected

Abbott established www.freestylecheck.com as the primary verification portal where patients can confirm sensor status [1]. The verification process requires users to locate their sensor serial number, which appears in three distinct locations.

Users can find serial numbers through multiple access points:

1. In the FreeStyle Libre 3 app: Navigate to the Main Menu, select “About Screen,” and locate the serial number under “Last 3 Sensors” [1]
2. In the Libre app: Access the bottom Menu, select Profile, then About, and find the serial number under “Last 3 Sensors” [1]
3. On the FreeStyle Libre 3 Reader: Go to Settings Menu, select “System Status,” then “System Info” [1]
4. On product packaging: Check the label on the bottom of the sensor applicator or carton [1]

Patients using sensors with connected insulin delivery devices should refer to the device user manual for serial number location instructions [1]. After locating the serial number, users must visit www.freestylecheck.com and select “CONFIRM SENSOR SERIAL NUMBER” [1]. The website prompts users to enter their valid serial number for verification [1].

Provided that verification confirms a potentially affected sensor, the website instructs patients to enter contact information for free replacement product delivery [1]. Abbott processes replacement requests at no cost to affected users [3]. Patients can also contact Abbott Diabetes Care at 1-833-815-4273 for recall-related inquiries [5].

How to Safely Dispose of Recalled Sensors

Patients must immediately discontinue use upon confirmation that their sensor is affected [1]. This applies to both currently worn sensors and unused devices in storage. Disposal should occur without delay once verification confirms impact status [1]. Abbott provides no specific disposal method instructions beyond immediate discontinuation [1].

Alternative Methods for Glucose Monitoring

Blood glucose meters serve as the primary alternative for patients awaiting replacement sensors [1]. These traditional fingerstick testing devices provide accurate readings when continuous glucose monitoring becomes unavailable. The FreeStyle Libre 3 Reader contains a built-in meter that patients can use for treatment decisions [1]. This integrated feature eliminates the need for separate testing equipment while replacement sensors ship to affected customers.

When to Use Blood Glucose Meters Instead

Patients should use blood glucose meters or the built-in reader meter whenever sensor readings fail to match symptoms or expectations [1]. This precaution applies to all freestyle libre 3 users, regardless of recall status. Discrepancies between physical symptoms and displayed glucose levels indicate potential sensor malfunction requiring immediate verification through alternate testing methods [3]. Blood glucose meters deliver definitive measurements for treatment decisions when sensor accuracy remains uncertain.

Abbott Identifies Manufacturing Defect and Offers Free Replacements

Abbott resolved the manufacturing issue after identifying its source within a single production line among several facilities producing FreeStyle Libre 3 sensors [3]. The company completed its investigation and implemented corrective measures to prevent future occurrences of this defect [7]. This targeted resolution allowed Abbott to maintain operations at other production lines while addressing the specific source of inaccurate readings.

Root Cause: Single Production Line Identified

Internal testing revealed that one production line among multiple facilities manufacturing Libre 3 and Libre 3 Plus sensors generated the defective units [3]. Abbott traced the accuracy problem to this specific line rather than a systemic manufacturing flaw affecting all production processes. The company has since corrected the manufacturing issue that caused sensors to display incorrect low glucose readings.

The isolated nature of the defect explains why approximately 3 million sensors from this particular line required correction while other production facilities continued normal operations [3]. Abbott maintains several production lines for these sensors, and only units from the affected line exhibit the reading errors. This specificity enabled the company to implement targeted fixes without disrupting entire manufacturing operations.

How to Request Your Replacement Sensor

Patients who confirm their sensor is affected through www.FreeStyleCheck.com can request replacements directly through the same portal [7]. The website provides detailed instructions for submitting replacement requests after verification confirms impact status [3]. Abbott processes these requests at no charge to affected users [3].

The online replacement form requires specific acknowledgments before processing. Users must confirm they did not experience loss of consciousness or seizure related to the product issue [9]. Correspondingly, the form requires confirmation that users did not require medical or self-administered intervention, including consuming food, self-injecting insulin, or applying ointments due to sensor problems [9]. Abbott processes sensitive data, including medical history and health conditions, to report sensor issues and fulfill replacement requests [9].

Patients can contact Abbott Diabetes Care customer service at 1-833-815-4273 for replacement assistance or questions about the correction [3]. The customer service line operates seven days per week from 8 a.m. to 8 p.m. Eastern Time [3]. Representatives can verify sensor status and guide patients through the replacement request process by phone.

Expected Supply and Distribution Timeline

Abbott expects no major supply delays for replacement devices or new orders [7]. The company continues producing sensors through its standard processes and anticipates no significant supply disruptions resulting from this correction [10]. Production continues at unaffected manufacturing lines while the corrected line resumes operations under enhanced quality controls.

Free replacement sensors ship to affected customers after Abbott processes their requests through the online portal or customer service channels. The company maintains adequate inventory levels to fulfill replacement demands while meeting ongoing market needs for new sensor orders.

What Healthcare Providers and Distributors Need to Know

Healthcare professionals and distributors play critical roles in ensuring patients receive timely information about affected FreeStyle Libre 3 sensors and access replacement devices safely.

Instructions for Medical Professionals

Medical professionals must inform all patients using FreeStyle Libre 3 or FreeStyle Libre 3 Plus sensors about this recall [1]. Healthcare providers should instruct patients to visit www.FreeStyleCheck.com to verify sensor status [11]. Abbott Diabetes Care supplied patient letters specifically designed for provider distribution to affected individuals [1].

When patients confirm their sensor is impacted through the verification website or customer service representative, healthcare providers must direct them to immediately discontinue use and dispose of affected sensors [1]. Patients can request replacements through www.FreeStyleCheck.com by selecting “CONFIRM SENSOR SERIAL NUMBER” and entering their valid serial number [11]. If the sensor is confirmed as potentially impacted, the website prompts users to enter contact information for free replacement product delivery [11].

Healthcare providers should advise patients to use blood glucose meters or the built-in meter in the FreeStyle Libre 3 Reader for treatment decisions when sensor readings don’t match symptoms or expectations [1]. This guidance applies to all monitoring situations where sensor accuracy remains uncertain.

Sales representatives will contact healthcare providers with specific instructions for disposing of impacted sample units [11]. Abbott provides sample replacements following proper disposal procedures [11].

Guidance for Distributors and Wholesalers

Distributors and wholesalers must notify customers about this Urgent Medical Device Correction and arrange for impacted sensor returns through standard return processes [1]. Distribution facilities should check inventory for sensors from affected lots and remove them immediately [1]. These products must be returned using normal return procedures established with Abbott [1].

How to Access Patient Communication Materials

Abbott Diabetes Care provides patient letters through healthcare providers for distribution to affected users [1]. These materials contain verification instructions and replacement request procedures tailored for patient understanding.

Customers with adverse reactions, quality problems, or recall questions should contact Abbott Diabetes Care at 1-833-815-4273 [11]. Adverse reactions or quality problems may be reported to the FDA’s MedWatch Adverse Event Reporting program online, by regular mail, or by fax [11].

Need for Better Quality Control of Devices

The FreeStyle Libre 3 sensor recall demands immediate attention from diabetes patients, healthcare providers, and distributors alike. Above all, device accuracy forms the foundation of safe diabetes management, and this manufacturing defect compromises that critical function. Patients must verify their sensors through www.freestylecheck.com without delay and switch to blood glucose meters until replacement devices arrive. Abbott’s commitment to free replacements addresses the immediate supply concern, yet the 860 serious injuries and seven deaths underscore the potentially life-threatening consequences of sensor malfunction. This situation reinforces the essential need for backup monitoring methods and vigilant symptom awareness when managing chronic conditions dependent on medical technology.
