Announcement: FreeStyle Libre 3 Plus to Replace Current Sensors
21/Jul
The FreeStyle Libre 3 Plus is set to revolutionise glucose monitoring across the UK, with Abbott announcing its official replacement of previous FreeStyle Libre sensors. With improved accuracy, extended wear, and superior app integration, the FreeStyle Libre 3 Plus is not just an upgrade—it’s a complete game-changer in diabetes management.
This announcement signals a new era in Continuous Glucose Monitoring (CGM) technology, combining ease of use, better insights, and enhanced patient outcomes. Designed with user comfort and NHS cost-efficiency in mind, this next-generation sensor will soon become the default option for existing and new users across the country.
What Is the FreeStyle Libre 3 Plus?
The FreeStyle Libre 3 Plus is a next-gen CGM system that offers real-time glucose readings directly to a smartphone every minute. Like its predecessors, it is factory-calibrated and requires no finger-prick calibration. However, what sets it apart are the refined features aimed at boosting accuracy, reducing discomfort, and improving long-term diabetes care.
Key highlights include:
- 15-day wear duration (compared to 14 days in previous models)
- Enhanced sensor accuracy, especially in hypoglycaemic and hyperglycaemic ranges
- Smaller and thinner sensor profile for discreet use
- Seamless integration with the FreeStyle LibreLink app and third-party digital health platforms
This model retains the affordability and NHS reimbursement eligibility of the earlier FreeStyle Libre models, ensuring continued accessibility for users.
Why Is FreeStyle Libre 3 Plus Replacing Previous Sensors?
Improved Accuracy Across the Board
One of the core reasons for the shift is clinical accuracy. FreeStyle Libre 3 Plus offers better Mean Absolute Relative Difference (MARD) scores than earlier versions, which means readings are closer to true blood glucose values. This is critical for both insulin dosing and lifestyle decisions.
Extended Wear Time with More Stability
With a 15-day wear duration, users experience fewer sensor changes each month, reducing costs and interruptions. The new sensor uses advanced adhesive technology to provide a more secure yet skin-friendly experience for longer periods.
Real-Time, Minute-by-Minute Readings
Unlike older models that required scanning, the Libre 3 Plus pushes glucose data automatically every minute to a user’s smartphone. This real-time insight allows for better glucose trend monitoring and reduces the chances of hypo- or hyperglycaemic events.
Streamlined NHS and Pharmacy Supply Chains
The introduction of a single standardised sensor simplifies logistics for the NHS and pharmacies. With fewer SKUs to manage, stock issues and prescribing errors are expected to drop significantly, improving continuity of care.
Who Will Be Affected by the Transition?
Current FreeStyle Libre Users
If you’re using the FreeStyle Libre 2, FreeStyle Libre 3, or the original Libre system, your prescriptions will gradually be updated to the Libre 3 Plus. You won’t need to take action—GP practices and pharmacies will handle the transition automatically unless you opt out for clinical reasons.
New Users and Diagnosed Patients
Newly diagnosed individuals or those moving to CGM for the first time will be started directly on the FreeStyle Libre 3 Plus, benefiting immediately from its advancements.
Benefits of FreeStyle Libre 3 Plus for Diabetes Management
1. Real-Time Data = Better Control
Receiving glucose updates every minute allows users to detect trends and act proactively, significantly reducing the risk of dangerous sugar fluctuations.
2. Compact Design with Better Comfort
The Libre 3 Plus is Abbott’s smallest sensor yet, almost 70% smaller than Libre 2, sitting closer to the skin and allowing for more freedom of movement and less visibility under clothing.
3. Zero Finger-Prick Calibrations
Users continue to benefit from a needle-free experience, with no need for finger-prick calibration—especially beneficial for younger patients and those with needle aversions.
4. Improved Data Sharing
With Libre 3 Plus, data can be easily shared with caregivers, family members, or healthcare providers in real time, making remote monitoring more efficient for both Type 1 and Type 2 diabetes patients.
How to Transition to FreeStyle Libre 3 Plus
Prescription Updates
Most users will receive Libre 3 Plus sensors through their existing NHS prescriptions automatically. Check with your GP or diabetes nurse to confirm the timing of your switch.
App Compatibility
Ensure your smartphone is updated and compatible with the FreeStyle LibreLink app. This is essential as the Libre 3 Plus no longer requires or supports separate readers—it’s app-exclusive.
Disposal and Replacement of Older Sensors
While there’s no urgency to discard your current sensors, future refills will likely only include Libre 3 Plus versions. Abbott will continue providing support for the transition period.
Clinical and Market Impact
Greater Alignment with NICE Guidelines
The new sensor supports better alignment with NICE recommendations for CGM use in both Type 1 and selected Type 2 diabetes patients. The improved accuracy and real-time alerts are particularly useful in high-risk groups.
Enhanced Data for Healthcare Providers
Libre 3 Plus integrates with LibreView, Abbott’s cloud-based platform, giving clinicians access to more detailed reports and trends. This helps them make more informed decisions during reviews or insulin adjustments.
Competitive Edge in the CGM Market
By replacing older models with a superior yet cost-equivalent sensor, Abbott solidifies its position as the leading CGM provider in the UK. Competitors will likely struggle to match both the technical innovation and the broad NHS distribution model that FreeStyle Libre 3 Plus offers.
Final Thoughts: A Defining Move in Diabetes Tech
The replacement of FreeStyle Libre 2 with Libre 3 Plus is more than a product swap—it’s a technological leap that brings patients closer to real-time, accurate, and user-friendly diabetes care. For healthcare systems, it simplifies supply chains, reduces cost variability, and improves standardisation.
For patients, it’s a future of fewer finger pricks, better control, and more confidence.
