Abbott today announced that the U.S. Food and Drug Administration (FDA) has cleared a reader for its FreeStyle Libre 3 integrated continuous glucose monitoring (iCGM) system, which features the world's smallest, thinnest and most discreet glucose sensor. With the FDA's clearance of a standalone reader, Abbott is working to get the FreeStyle Libre 3 system added to Medicare's list of covered systems as soon as possible.
