Abbott’s FreeStyle Libre 2 System is at the forefront of continuous glucose monitoring (CGM) technology, known for its precision and extended 14-day wear time. Aimed at adults and children with diabetes, the device offers real-time glucose level alarms while advancing diabetes management. The FreeStyle Libre 2 has become crucial as diabetes has a significant and growing global impact, with nearly 10.5% of adults between the age of 20-79 years affected. This prevalence translates to a substantial market for CGM technologies.
The device, a wearable integrated CGM (iCGM), provides up to the minute glucose readings—a total of 1,440 per day, dramatically outperforming other CGMs that provide a mere 288 readings per day. This feature underscores the ability of FreeStyle Libre 2 to provide five times more frequent readings than its competitors, allowing for better monitoring and real-time adjustments.
MARD and Accuracy
Abbott promotes superior accuracy of the FreeStyle Libre 2 System by highlighting its Mean Absolute Relative Difference (MARD), a critical metric used to measure CGM performance. A lower MARD equates to better accuracy; for FreeStyle Libre 2, the MARD is reported at 9.3% overall for 14 days, surpassing other available iCGMs which show a higher overall MARD of 9.8% over ten days. The accuracy is further emphasized from day one, where the Libre 2 stands out against its competitors.
Alarm Performance and Sensor Longevity
Enhancing functionality, the device boasts one-third fewer false alarms in children compared to other available iCGMs. Moreover, the Libre 2 sensors last 40% longer than other wearable glucose sensors, reinforcing the system’s efficiency and user convenience.
Important Safety Information
Abiding by safety protocols and restrictions is essential for users of the FreeStyle Libre 2. The manual encapsulates key warnings and limitations. For instance, it’s necessary to remove the sensor before undergoing specific medical procedures such as MRI, CT scans, and X-ray. Additionally, high doses of Vitamin C can affect sensor accuracy. Users are cautioned to routinely match sensor readings with symptoms and confirm with fingerstick measurements when necessary.
Support and Information
Extending support to its users, Abbott provides a dedicated website and contact details for further enquiry into the usage, safety, and detailed indications of the FreeStyle Libre 2 system. The manual reiterates the importance of consulting medical professionals when needed and encourages visiting the official website for in-depth information.
