The FreeStyle Libre 3 System uses the same technology and delivers the same unsurpassed 14-day accuracy2 as the FreeStyle Libre 2 System with a mean absolute relative difference (MARD) of 9.2%2. No confirmatory finger pricks required for treatment decisions even when glucose is low, falling, or changing rapidly.
