Health Canada has given approval for Abbott’s FreeStyle Libre 2, a sensor-based glucose monitor for patients aged four years and older.

The continuous glucose monitor features optional real-time alarms when patients experience hypoglycemia or hyperglycemia. The monitor can be worn on the back of the upper arm for up to two weeks.

The wearable, Bluetooth-enabled device eliminates the need for fingersticks and can conduct a one-second scan using a smartphone app or a handheld reader.
