Abbott’s FreeStyle Libre 2 glucose-monitoring system, which comes with optional real-time alarms for high and low glucose levels, has been granted a CE Mark for use in European Union countries.
The FreeStyle Libre continuously measures glucose levels with a small sensor worn on the back of the upper arm for 14 days and provides glucose readings via a scanner that the user waves over, and is therefore sometimes referred to as « flash » glucose monitoring. Fingerstick readings aren’t required for calibration or making treatment decisions.
The original FreeStyle Libre was approved in the European Union in 2014 and in the United States in 2017. It is less expensive than other continuous glucose monitors and is used widely in Europe. But in the United States, the lack of alarms has been viewed by some as a disadvantage for patients with type 1 diabetes.
With Libre 2, patients can choose to customize either audible or vibration alarms for low and high glucose values as well as a signal loss. Those who don’t want the alarms can choose to leave them turned off.
In an Abbott statement, Jens Kröger, MD, of the Center of Diabetology Bergedorf, Hamburg, Germany, explains, « For some patients who are unaware of the hypoglycemia episodes they may be experiencing — especially during sleep — having alarms can be important.
