The FreeStyle Libre flash glucose monitoring system is clinically proven to be accurate, stable and consistent over 14 days. It does not require finger prick calibration and may be used in place of routine finger prick glucose testing.

In a clinical study1, the FreeStyle Libre system achieved 11.4% mean absolute relative difference (MARD) compared to blood glucose testing.
