FreeStyle Libre 2 Plus vs FreeStyle Libre 2: What’s the Real Difference?
Jan
Diabetes technology continues to move forward, and Abbott’s latest release—the FreeStyle Libre 2 Plus—is a great example of how small upgrades can make a meaningful difference in everyday life. While it builds on everything people already appreciate about the FreeStyle Libre 2—simple scanning, reliable tracking, and freedom from constant finger-pricking—it introduces thoughtful improvements that make glucose monitoring even smoother.
In this guide, we clearly explain the differences between the FreeStyle Libre 2 and the Libre 2 Plus, how these updates support daily diabetes management, and why upgrading could be a smart choice for many users.
1. Longer Sensor Wear Time
One of the most noticeable improvements is how long the sensor lasts.
- FreeStyle Libre 2 Plus: Designed to be worn for up to 15 days, giving you an extra day of use. While one day may seem minor, it reduces how often sensors need changing and means fewer disruptions throughout the month.
- FreeStyle Libre 2: Approved for 14 days of wear, which remains reliable but requires slightly more frequent replacements.
That extra day adds up to greater convenience over time.
2. Approved for Younger Children
The Libre 2 Plus expands access to continuous glucose monitoring for younger users.
- Libre 2 Plus: Approved for children from 2 years old.
- Libre 2: Approved for children aged 4 and above.
This change is especially valuable for parents of toddlers, allowing them to monitor glucose levels with fewer finger-prick checks and greater peace of mind—particularly overnight.
3. Enhanced Accuracy
Accuracy is essential for confident diabetes management, and the Libre 2 Plus delivers an improvement where it matters most.
- Libre 2 Plus: Offers a lower MARD of approximately 8.2%, meaning more precise readings, particularly during low glucose events.
- Libre 2: Provides dependable accuracy with a MARD of around 9.2%.
What is MARD?
MARD (Mean Absolute Relative Difference) measures how close sensor readings are to actual blood glucose values. The lower the number, the more accurate the sensor. In practical terms, the Libre 2 Plus provides readings that more closely reflect true glucose levels.
4. Improved Connectivity and App Stability
Upgrading doesn’t mean changing your routine or buying new equipment.
- Libre 2 Plus: Works seamlessly with the existing FreeStyle LibreLink app and the Libre 2 reader. Bluetooth connectivity has been improved for smoother syncing and fewer dropped connections.
- Libre 2: Uses the same app and reader but may occasionally experience brief Bluetooth interruptions.
This enhanced stability helps ensure alerts and readings are delivered when you need them most.
5. More Reliable Real-Time Alerts
Both systems offer optional alarms for high and low glucose levels, but the Libre 2 Plus strengthens this feature.
- Libre 2 Plus: Maintains a steadier Bluetooth connection and updates glucose data every minute, enabling faster and more reliable alerts.
- Libre 2: Provides the same alarms but may experience short delays if the Bluetooth signal drops.
This improvement is particularly helpful during sleep, exercise, or busy daily routines.
6. Insulin Pump Compatibility
One of the most significant upgrades is insulin pump integration.
- Libre 2 Plus: Approved for use with the Tandem t X2 insulin pump and the Omnipod 5 Automated Insulin Delivery System, enabling automated insulin adjustments based on real-time glucose readings.
- Libre 2: Shares glucose data via Bluetooth but cannot directly integrate with insulin pumps.
This makes the Libre 2 Plus suitable for closed-loop or hybrid closed-loop diabetes management systems.
7. Cost and Value
One of the best parts of upgrading is that it doesn’t cost more.
At The Care Pharmacy, the FreeStyle Libre 2 Plus is priced exactly the same as the Libre 2. Orders are dispatched quickly, with free delivery and some of the fastest turnaround times available—making it easy to access the latest technology without extra expense.
Who Should Consider Upgrading?
While the Libre 2 Plus is suitable for most users, some groups may benefit even more:
- Parents of young children: Now approved from age 2, it’s ideal for families managing diabetes in toddlers.
- Busy adults: Longer wear time means fewer sensor changes, perfect for travel, work, and active lifestyles.
- Those who rely on alerts: Improved Bluetooth stability ensures more dependable real-time notifications.
Final Thoughts
The FreeStyle Libre 2 Plus is a well-considered upgrade focused on comfort, reliability, and real-life usability. With longer wear time, improved accuracy, stronger connectivity, and insulin pump compatibility, it offers meaningful benefits without changing the tools or routines users are already familiar with.
If you’re currently using the FreeStyle Libre 2, upgrading through The Care Pharmacy is straightforward and cost-neutral. If you’re unsure which option is best for you, their knowledgeable team is always available to help guide your decision.
