Abbott Glucose Monitor Attorneys
When you rely on a glucose monitor to manage your diabetes, you’re trusting your health to those readings being accurate. If they’re not, the consequences can be serious and due to no fault of your own. Unfortunately, that’s exactly what some patients using the FreeStyle Libre 3 and FreeStyle Libre 3 Plus experienced.
Lawsuits filed against Abbott, the manufacturer, claim that the sensors gave readings lower or higher than the user’s actual glucose levels, which led to medical emergencies like diabetic ketoacidosis (DKA), seizures, and more.

Abbott Glucose Monitor Lawsuits
After inaccurate readings from Abbott’s FreeStyle Libre 3 and FreeStyle Libre 3 Plus devices were linked to 7 deaths, glucose monitor lawsuits have been filed across the United States, including several proposed class action lawsuits. Davonte Ford in California filed suit after inaccurate blood sugar readings in his father’s glucose monitor led to him administering the wrong treatments, which landed his father in the hospital, where he later died. 8 days later, the model of glucose monitor his father was using was recalled by Abbott.
Other lawsuits have been filed in Washington and North Carolina, as well as an additional lawsuit in California. These suits are still ongoing, and more may be filed in the weeks to come. Those who have already filed claim that Abbott’s recall isn’t broad enough for patients to trust that there aren’t more defective devices out there. Abbott has responded that the inaccurate readings were caused by a production line issue that has now been corrected and the defective devices recalled.
Abbott Glucose Monitor Recall
In November of 2025, Abbott issued a letter to medical professionals, device distributors, and customers stating that they were recalling the following devices:
- FreeStyle Libre 3 Sensor (model numbers 72081-01 & 72080-01)
- FreeStyle Libre 3 Plus Sensor (model numbers 78768-01 & 78769-01)
The instructions were to verify whether their glucose monitors were affected and, if they were, to discontinue use and dispose of them.
The FDA reported that the recall was due to the inaccurate readings produced by the recalled devices. These inaccurate readings were resulting in patients receiving incorrect treatments, leading to health complications or, in some cases, like Davonte Ford’s father, death.
What Is a Glucose Monitor?
Glucose monitors are medical devices designed to help those with diabetes monitor their blood sugar levels throughout the day. They typically involve a sensor that sits just underneath the skin that measures the amount of glucose in the cells on a continual basis, sending the information to an app or handheld receiver so that the user can make healthy, informed decisions about insulin, food, exercise, and medication.
These monitors are designed to replace having to manually check at different times throughout the day, instead monitoring glucose levels in real time and just alerting the patient when its too high or too low so they can take prompt action.
How Glucose Monitors Work
Continuous glucose monitors (CGM) track glucose not in the blood but in the fluid between your body’s cells. That information is then transmitted wirelessly to either a receiver or a smartphone app, so it’s easy for users to check their blood sugar throughout the day. If blood sugar is too high or too low, the app or receiver will alert the patient so they can take action right away.
Because the monitors measure glucose in fluid rather than the blood directly, there can actually be a delay as the readings can lag behind the real blood sugar levels. For that reason, the devices use built-in software to estimate what the blood sugar most likely is based on the data it already has.
Why Reliance on CGM Data Can Create Risk When Readings Are Inaccurate
Patients rely on the data from their glucose monitors to make decisions about when and what to eat, whether to take medication or insulin, or other important health decisions. CGMs can influence a wide range of activities, including:
- Determining insulin dosage
- Correcting bolus calculations
- Timing emergency responses
- Monitoring glucose overnight
People living with diabetes rely on this information to manage how much insulin to take and when, and to prevent health emergencies from happening. If that data isn’t accurate, it could cause someone to take the wrong amount of insulin, fail to take insulin when needed, or take insulin when it isn’t necessary. Any of those situations could be dangerous at best and deadly at worst.
What Is Diabetes?
Diabetes is a group of diseases that impact how the body uses blood sugar, also known as glucose. There are multiple types of diabetes, each with different causes, but all have in common that the body can end up with excess glucose in the blood, which can lead to health complications if left untreated.
Types of diabetes can include:
- Type 1 diabetes (in which the pancreas doesn’t produce enough insulin)
- Type 2 diabetes (in which the body doesn’t use insulin effectively)
- Prediabetes (high blood sugar, but not high enough to be considered diabetes)
- Gestational diabetes (occurs during pregnancy and may go away after birth)
Symptoms of Diabetes
Symptoms of diabetes depend more on how high your blood sugar is, rather than the type of diabetes. Type 1 diabetes patients do tend to experience symptoms more quickly and more severely than those with other types, however.
Symptoms can include:
- Frequent urination
- Feeling thirstier than usual
- Losing weight despite not trying to
- Ketones in the urine
- Feeling irritable
- Mood changes
- Tiredness
- Weakness
- Blurry vision
- Sores that don’t heal easily
- Frequent infections
The Role of Glucose in Diabetes
Glucose plays a major role in the normal functioning of the body. It’s what provides energy to the cells in the muscles and other parts of the body. Sugar from food and the liver gets absorbed into the bloodstream and, with the assistance of insulin, gets used by the cells. Diabetes occurs when the pancreas isn’t producing enough insulin or the body is not using that insulin effectively, or both. Without that insulin moving glucose into the cells, it builds up in the bloodstream, which can result in health complications.
How Glucose Monitors Help Treat Diabetes
Glucose monitors can play a very important role in the treatment of diabetes. Typically, diabetes is treated with monitoring blood sugar and taking insulin, in addition to healthy eating and staying active. Glucose monitors can alert users when their blood sugar is either too high or too low, so they can promptly eat something or take insulin, depending on what is needed in the moment.
Without a continuous monitor, people with diabetes would have to check their blood sugar on a regular basis, often at specific times such as upon waking, after eating, etc. With a CGM, however, they should instead be able to rely on the device to let them know if there’s been a change in their blood sugar.
Why Inaccurate Glucose Readings Can Be Dangerous
Inaccurate glucose readings are dangerous because they can cause patients to make treatment decisions that push blood sugar levels outside a safe range. When glucose levels remain too high or drop too low, the body’s normal metabolic balance is disrupted. Severe imbalances can quickly escalate into medical emergencies requiring urgent intervention.
The ongoing lawsuits focus on whether inaccurate device readings contributed to these life-threatening events.
How Inaccurate Readings Can Lead to Hospitalization
Inaccurate readings can lead to hospitalization when treatment decisions based on incorrect data cause a severe metabolic imbalance.
For example:
- False low readings may result in skipped insulin doses, increasing the risk of diabetic ketoacidosis or hyperosmolar hyperglycemic state.
- False high readings may result in excessive insulin dosing, leading to severe hypoglycemia, seizures, or loss of consciousness.
In both scenarios, the body’s glucose regulation can become unstable. Prolonged high glucose can lead to severe metabolic complications, while excessive insulin can cause blood sugar to drop to dangerously low levels.
Because CGMs often replace frequent fingerstick testing, patients may rely heavily on device data. If inaccurate readings are not verified during critical moments, the risk of severe consequences increases.
Who Manufactures the FreeStyle Libre Glucose Monitor?
Abbott Diabetes Care, a division of Abbott Laboratories, develops, manufactures, markets, and distributes the FreeStyle Libre product line worldwide. As a medical device manufacturer, Abbott is subject to federal regulatory oversight, including FDA premarket clearance requirements and post-market surveillance obligations.
Manufacturer’s Responsibility for Safety
Before a device reaches the market, manufacturers must demonstrate safety and effectiveness through clinical data and performance testing. Once approved or cleared, the manufacturer has ongoing responsibilities, including:
- Monitoring adverse event reports
- Conducting quality control testing
- Investigating field complaints
- Reporting certain issues to regulators
- Implementing corrections or recalls when necessary
Manufacturers also have a duty to provide adequate warnings and instructions so that users understand limitations and risks.
Abbot’s Actions To Provide Safety for Patients
In the case of FreeStyle Libre 3 and 3 Plus sensors, Abbott initiated a medical device correction after internal testing suggested that some sensors could provide incorrect low glucose readings. That action included instructions for replacement in certain cases and safety notices to patients and healthcare providers.
Public legal claims focus on what Abbott knew about the accuracy problem, when it received information about it, and how it responded, particularly whether warnings were sufficient and timely given the serious consequences alleged.
What Injuries and Medical Emergencies Are Linked to the Abbott Glucose Monitor?
Patients using glucose monitors rely on the devices to alert them when their blood sugar is too high or too low. If that data is incorrect, it could lead to the incorrect usage of insulin or other treatments, which can result in health complications, such as:
Diabetic Ketoacidosis (DKA)
DKA occurs when the body lacks sufficient insulin and begins breaking down fat for energy, producing ketones that accumulate in the blood. Elevated ketones create metabolic acidosis, which can impair organ function.
Symptoms often include:
- Nausea and vomiting
- Abdominal pain
- Rapid breathing
- Confusion
- Fruity breath odor
Without prompt treatment, DKA can progress to coma or death. Hospitalization typically involves IV insulin, fluids, electrolyte replacement, and intensive monitoring.
Hyperosmolar Hyperglycemic State (HHS)
HHS is characterized by extremely high blood glucose levels, severe dehydration, and increased blood osmolarity. Blood osmolarity refers to the concentration of dissolved substances in the blood, including glucose and electrolytes. When glucose levels become extremely elevated, the blood becomes abnormally concentrated, or “hyperosmolar.” This high concentration pulls water out of the body’s cells and tissues, leading to profound dehydration and impaired organ function.
HHS often develops more gradually than diabetic ketoacidosis but can be equally dangerous.
Patients may experience:
- Extreme thirst
- Altered mental status
- Weakness
- Confusion
HHS frequently requires hospitalization, ICU-level monitoring, and aggressive intravenous fluid and insulin therapy.

Severe Hypoglycemia
Severe hypoglycemia may occur when blood glucose drops to critically low levels. The brain depends on glucose for function, and rapid declines can lead to:
- Seizures
- Loss of consciousness
- Brain injury
- Coma
Emergency treatment may involve intravenous glucose or glucagon administration.
These medical events are not minor complications. They are life-threatening crises that may have long-term consequences.
Who Qualifies for an Abbott Glucose Monitor Lawsuit?
You may qualify if you were diagnosed with diabetes, used a qualifying FreeStyle Libre device between 2022 and the present, received inaccurate readings, and were hospitalized as a result.
To meet general screening criteria, the patient must have:
- A diagnosis of Type 1 Diabetes, Type 2 Diabetes, or Gestational Diabetes
- Used a FreeStyle Libre 3 (age 4+) or FreeStyle Libre 3 Plus (age 2+)
- Experienced inaccurate high or low glucose readings
- Been hospitalized for DKA, HHS, severe hypoglycemia or hyperglycemia, seizure, coma, accident-related injury, or death
The legal focus is whether inaccurate readings contributed directly to a serious medical emergency.
What Compensation May Be Available in an Abbott Glucose Monitor Lawsuit?
Compensation may include reimbursement for emergency medical care, ICU treatment, follow-up visits, and long-term medical management. Patients who missed work may seek lost wage damages. In cases involving lasting impairment, reduced earning capacity may also be considered.
Pain and suffering damages may apply in severe cases. When a death occurs, eligible family members may pursue wrongful death damages under applicable state law.
Why You Should Act Quickly After a Glucose Monitor Injury
Product liability claims are subject to statutes of limitations that vary by state. Missing a filing deadline can permanently bar recovery.
Early consultation allows attorneys to preserve critical evidence, including device data, serial numbers, packaging, and medical records. It also ensures that deadlines are identified before they expire.
