Clinically Proven Accuracy1

99.9% of glucose results fall within Zones A and B of Consensus Error Grid3

Sensor readings show minimal variance in performance

Consensus Error Grid Analysis evaluating CGM accuracy with regard to clinical decisions. CGM errors are translated into the potential clinical consequences of the errors.4 Data are plotted vs YSI reference in the scatterplot, and the error grid is divided into zones, with Zone A representing the greatest accuracy:

Freestyle Libre 2 System

Zone A: No effect on clinical action (considered clinically accurate)

Zone B: Altered clinical action, but no or little effect on clinical outcome

Zone C: Altered clinical action—likely to affect clinical outcome

Zone D: Altered clinical action—could have significant medical risk

Zone E: Altered clinical action—could have dangerous consequences

YSI Reference (mg/dL).
N=17,477 paired data points.
93.3% of glucose results within Zone A.

Based on FDA iCGM special controls.

MARD (mean absolute relative difference) is compared to reference YSI (Yellow Springs Instrument) values.
