Millions of Abbott glucose sensors recalled due to inaccurate readings

Continuous glucose monitors are essential tools for millions managing diabetes, but the U.S. Food and Drug Administration (FDA) has issued a warning about certain Abbott sensors that may deliver incorrect blood sugar readings, potentially leading to unsafe treatment choices.

The recall involves approximately 3 million FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors. Other Libre devices are not affected. Globally, these inaccurate readings have been associated with at least seven deaths and over 700 serious injuries. In the United States, around 60 serious incidents were reported, though none were fatal.

The FDA advises patients to check if their sensors are part of the recall and to stop using and properly dispose of any affected devices immediately.

Incorrect glucose readings can pose serious health risks. For example, a falsely low reading might cause a person to consume extra carbohydrates or reduce insulin doses, mistakenly thinking their blood sugar is controlled. Over time, these errors could result in severe health consequences, including injury or death.

The FDA classifies this problem as "potentially high-risk" and plans to release updates as new information emerges. Abbott stated that a manufacturing defect caused the issue, which has now been resolved, and the company does not anticipate significant delays in supplying replacement sensors or fulfilling new orders.

Diabetes impacts roughly 38 million people in the United States. Those concerned can visit FreeStyleCheck.com to determine if their sensor is affected and request a free replacement.
