More insight than monitoring alone

Continuous glucose monitoring provides a more complete picture of a patient’s glucose levels, compared to what you can obtain from a blood glucose meter (BGM). More frequent access to glucose insights leads to more effective diabetes management, for you and your patients.9,|| 

Real-time readings are sent to a compatible smartphone or watch and alerts can warn patients when glucose levels are becoming too high or too low.
