Accuracy
Accuracy in CGMs is measured by MARD (Mean Absolute Relative Difference). A lower MARD means the sensor readings are closer to a lab blood-glucose reference. Both sensors deliver clinically accurate results.

Libre 3
7.8%
MARD
Libre 3 holds a slight edge on MARD. In everyday use, the difference between 7.8% and 8.66% is small enough that both sensors are considered clinically reliable for glucose trend monitoring. What matters more is consistent wear and checking trends rather than any single reading. Always consult your doctor before making treatment decisions based on CGM data.
Sensor Duration & Size
Longer wear time means fewer sensor changes and less disruption. Smaller sensors are more discreet under clothing.
Wear Time
Vixxa 2 lasts 1 extra day per sensor
Diameter
Nearly identical footprint
Weight
Libre 3 is lighter
