In a study conducted by Abbott Diabetes Care, 94% of patients surveyed (n=122) agree that the FreeStyle Libre sensor is comfortable to wear.ĭata on file, Abbott Diabetes Care.

Self-Monitoring Technologies for type 2 Diabetes and the Prevention of Cardiovascular Complications: Perspectives from End Users. Perspectives of patients with type 1 or insulin-treated type 2 diabetes on self-monitoring of blood glucose: a qualitative study. † This means they can be confident in the accuracy of the system, and they can be confident the accuracy they're receiving is what is reported, without being affected by discrepancies caused by finger prick calibration.įind out more about flash glucose monitoring and the FreeStyle Libre 2 system in our FreeStyle Academy The FreeStyle Libre 2 flash glucose monitoring sensor is calibrated at the factory - so people with diabetes won’t need to calibrate it using a finger prick, ever. 7Ĭalibration is needed for commercially available CGM systems because the sensitivity of each sensor can vary within each batch that is made. The consensus Error Grid below shows 99.9% of readings in Zone A + B of the Consensus Error Grid. The higher the percentage of readings in Zones A and B, the more accurate the sensor is. This is reflected by the Consensus Error Grid by various areas on the graph labelled A to E. The closer the sensor reading to the reference blood glucose meter reading, the better the accuracy. The comparison between the 2 different readings is plotted on a graph called a Consensus Error grid. In this case the reference is a finger prick blood glucose reading which is taken at the same time as the sensor scan. To assess the accuracy of the FreeStyle Libre 2 sensor, the glucose readings the sensor provides are compared to a known independent reference. The FreeStyle Libre 2 system is accurate, stable and consistent over 14 days 7 without the need for fingerprick calibrations †. How accurate are the FreeStyle Libre Systems? People with diabetes must scan once every 8 hours for a complete glycaemic picture, ensuring they remain engaged with their glucose monitoring throughout the day. They consist of a small, discreet sensor worn on the back of the arm with a reader or phone app ◊ to scan the sensor.
It does not include alarms for real-time low or high blood sugars, and the data is not currently streamed to mobile devices like smartphones.The FreeStyle Libre systems are the leading sensor glucose monitoring devices globally 5 and the only flash glucose monitoring systems in the UK. For a glucose reading you must hold the handheld device over the sensor.
The FDA has categorized it under the CGM umbrella rather than create an entirely new category. It is important to keep in mind that the Libre System is a Flash Glucose Monitoring device and not a CGM. Wear Time: The Sensors are approved for 10 days of use.Īge of Use: The FDA approval is for ages 18 and older.īuilt-in Meter: You’re still able to test your blood sugar with a FreeStyle test strip if you feel the need to. Trends: Identify glucose level trends with a directional arrow and review 8 hours of glucose history. Glucose Readings: Capture real-time painless glucose readings with use of a hand-held reader over the sensor. Self-Apply / Scannable Sensor: The sensor is approximately the size of two stacked quarters, applied to the back of the upper arm. Some of the key items to know about the FreeStyle Libre System: Abbot claims that it’s longer lasting, less bulky compared to other Continuous Glucose Monitors (CGM) available in the U.S., and studies have shown that people who use the FreeStyle Libre system test their glucose levels more frequently, with less time in hypoglycemia.
Abbott’s revolutionary device is called the FreeStyle Libre Flash Glucose Monitoring System and its goal is to eliminate the need for routine finger sticks / finger stick calibration.
FDA approval for a new Blood Glucose Monitoring (BGM) system has the diabetes community celebrating.
