FDA has cleared an Abbott 510(k) for a reader for its FreeStyle Libre 3 integrated continuous glucose monitoring system. The reader is a small handheld device that displays real-time glucose readings obtained from a small sensor worn on the back of a person’s upper arm, allowing them to manage their diabetes, the company says. “People who use the FreeStyle Libre 3 system will still have the option to use the current FreeStyle Libre 3 smartphone apps,” it adds.

The reader uses a rechargeable lithium-ion battery. “The user manual for the FreeStyle Libre 3 reader provides details on how to safely store, charge and use the device, including always using the Abbott-provided USB cable and power adapter,” Abbott says. Earlier this month, an FDA safety notice warned ([see story](https://www.fdaweb.com/abbott-safety-notice-on-freestyle-libre-readers/)) that if the FreeStyle Readers are not properly stored, charged, or used with the Abbott-provided yellow USB cable and power adapter, a potential exists for battery swelling and “extreme overheating, which may pose a fire hazard.”
