The arm and chest sites were most preferred, with the greatest sensor failures from the back. Conclusions: The FSL-CGM is clinically accurate when the sensors are applied to alternate chest or back sites.

The much-anticipated FreeStyle Libre 3 system - featuring the world's smallest, thinnest1 glucose sensor (about the size of two stacked U.S. pennies) - has received CE mark for people with diabetes in Europe.

Both the Dexcom G7 and FreeStyle Libre 3 sensors are smaller and lighter than previous versions. So much so that some early users and testers reported forgetting the device was even attached. The only downside - and it's a small one - is the user might accidentally knock it off because they forget they are wearing it.

Where FreeStyle Libre 2 is about the size of two U.S. quarters stacked, FreeStyle Libre 3 is smaller, about the size of two U.S. pennies stacked. That size reduction - by more than 70%10 - makes FreeStyle Libre 3 more environmentally sustainable.

When will we get the indication for it? The FreeStyle Libre system is only approved for use on the back of the upper arm as this was used to collect data in our pivotal clinical studies.

Accuracy. MARD (mean absolute relative difference) is a metric that indicates the accuracy of a CGM system in measuring glucose values. The lower the MARD, the more accurate. Both the Libre FreeStyle 3 and the Dexcom G7 have better MARD than their previous version and are highly accurate.

The Freestyle Libre 3, unlike the Freestyle Libre 2 sends the glucose readings automatically to the user's smartphone every minute. The phone can receive information from up to 33 feet away. The sensor stores 14 days of data in case the phone is out of range of the sensor.

The FreeStyle Libre 14 day Flash Glucose Monitoring System is a continuous glucose monitoring (CGM) device indicated for the management of diabetes in persons age 18 and older. It is designed to replace blood glucose testing for diabetes treatment decisions.

The FreeStyle Libre 3 system has many improvements compared to the Freestyle Libre 2 and 14-day systems. The sensors are smaller, easier to attach, and they track glucose readings much better. It should be more convenient to use and is expected to cost the same.

The Adhesive Irritates My Skin Some patients experience mild or serious skin irritation in response to the sticky stuff that Abbott uses on the Libre sensor. Symptoms may include rash and itchiness, or worse.
