They link 7 deaths and more than 700 injuries to critical reading problem on glucose monitors
Incorrect glucose readings can lead to inadequate treatment, even putting lives at risk
Certain Abbott Diabetes Care glucose monitors have shown incorrect readings, resulting in the deaths of at least seven people and more than 700 serious injuries. The U.S. Food and Drug Administration (FDA) has issued an alert regarding the issue. They indicate that a total of approximately 3 million FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors are involved in this incident. Abbott advises patients to visit FreeStyleCheck.com to check if their sensors are affected and obtain a free replacement, reports CNN. It is worth noting that inaccurate glucose readings can lead to inappropriate treatment and even be life-threatening. The FDA considers the manufacturing problem to be high-risk and is continuously updating its website with relevant information. Patients should immediately stop using the damaged sensors and discard them.
“Incorrect low glucose readings over a prolonged period can lead to incorrect treatment decisions for people with diabetes, such as excessive carbohydrate consumption or skipping or delaying insulin doses,” the agency stated.
“These decisions can pose serious health risks, including possible injury or death, or other less serious complications,” the FDA warned.
Abbott, for its part, confirmed that the manufacturing problem has been resolved and states that there will be no significant disruptions in supply or replacements.
Impact on Public Health
Incorrect glucose readings can lead to inappropriate treatment decisions, increasing the health risks associated with diabetes.
The public health agency warns that this could result in serious complications, including death.
According to the Centers for Disease Control and Prevention (CDC), diabetes is the seventh leading cause of death in the United States, a country where approximately 1 in 10 people (about 38 million) suffer from this disease.
Impact on confidence
The recent sensor failure in Abbott Diabetes Care's FreeStyle Libre 3 and 3 Plus continuous glucose monitors significantly reduces patient confidence in this technology.
These devices have reported incorrectly low glucose readings, linked to 736 adverse events, raising concerns about their reliability for critical therapeutic decisions.
Previous studies indicate that perceived accuracy is key to adherence: 34% of former users abandoned the systems due to distrust in the readings, and false alarms exacerbate "alert fatigue."
Abbott and the FDA are urging a halt to the use of affected sensors (specific models such as 72081-01), offering free replacements and verification with alternative blood glucose meters. This could mitigate short-term harm, but events like this highlight the need for greater transparency to restore long-term trust in glucose monitors.
