Made in USA
Introducing the world’s smallest, thinnest, and most discreet continuous glucose monitoring sensor: the Freestyle Libre 3 CGM. The Libre 3 sensor is so small and thin that it can be worn discreetly under your clothes, and there is no need to prick your finger to get a blood sample.
The makers of the FreeStyle Libre systems, Abbott, announced this October that the Freestyle Libre 3 continuous glucose monitoring system is now available in the U.S. following its FDA clearance back in May of 2022.
Difference Between Libre 2 and Libre 3
You may be familiar with the FreeStyle Libre 2 system, which was released in 2020. The Libre 3 is the latest version of this system, and it offers a few changes over its predecessor.
Size
Perhaps the most significant improvement is the size of the sensor. Previously, the Libre 2 system’s sensor was about the size and thickness of two quarters. Now, with the Libre 3, the sensor is smaller than two stacked pennies.
While it may not seem like a big difference, this reduced size makes the sensor much more comfortable to wear and far less noticeable under clothing, which is impressive considering the previous model was one of the smallest sensors in the industry.
Improved Accuracy
Much like its predecessor, this small device is the most accurate no-prick 14-day CGM system on the market. According to Abbott, the Libre 3 has an overall mean absolute relative difference (MARD) of 7.9%, whereas the Libre 2 has a MARD of 9.2%. Libre 3 is more accurate than ever.
Sensor/Applicator Combined
The new FreeStyle Libre 3 easier is now just one piece. With the improved new design the sensor comes with a preloaded applicator making it easier than ever to install the sensor.
Libre 3 readings can be influenced by other factors.
The Libre 3 can be influenced by a few factors that can change the way the glucose reading is read. These factors can change the reading:
- Taking more than 500 mg per day of vitamin C (ascorbic acid)
- Wearing the new sensor within the first 12 hours
- The sensor is not securely applied
- The sensor was stored in a non-temperature-controlled environment. You want to store these sensors indoors at the temperature range of 36°F to 82°F
No Reader – App Only!
Unlike the Libre 2, which offers the choice of a reader and app, the Libre 3 is not going to be paired with a reader. Instead, the only way to view your glucose data is with their LibreView app.
The app is available for both iOS and Android devices, but the app may not be compatible with certain devices and operating systems. It’s best to visit the Abbott website or review this guide for more information about device compatibility before using the app.
The app allows you to see your real-time glucose readings, as well as your history. Additionally, the app will also give you alerts if your glucose levels are getting too high or too low and the option to set additional alarms.
The Downside!
While this is not an issue for some, those who prefer the reader or have an incompatible device may find this undesirable change to be a bit of a nuisance. The other downside is phone battery usage.
When using your phone, you’ll need to connect the app and sensor using Bluetooth, which will make your phone’s battery drain faster. While using your phone, you’ll definitely notice that you need to charge it more, and sometimes depending on your phone it may not even last the entire day if you’re using your it often. If you’re familiar with using other Bluetooth devices, like a smartwatch, then you know how quickly a phone’s battery can deplete.
Conclusion
The Freestyle Libre 3 is the newest version of Abbott’s popular FreeStyle Libre system. The Libre 3 sensor provides you with real-time glucose readings every minute, which can be conveniently accessed on your smartphone. The app is available for both iOS and Android devices, but the app may not be compatible with certain devices and operating systems. The Libre 3 is also smaller and more discreet than the previous model.
Overall, the Freestyle Libre 3 is a convenient and discreet way to manage your diabetes.
