From Accuracy To Convenience Find The Difference Between Freestyle Libre 2 And 3

difference between freestyle libre 2 and 3


Continuous glucose monitoring (CGM) devices have become increasingly popular in managing diabetes. CGM systems provide real-time glucose level data, allowing individuals with diabetes to make informed decisions about their food intake, insulin dosing, and physical activity. Two popular CGM systems are the Freestyle Libre 2 and 3.

They use a sensor to measure glucose levels in the interstitial fluid. The sensor is placed on the back of the upper arm and can be worn for up to 14 days. The sensor measures glucose levels every minute, and the data is transmitted wirelessly to a receiver or smartphone app.

This article will compare and contrast the difference between Freestyle Libre 2 and 3, focusing on accuracy, convenience, cost, and user feedback.


The accuracy of a CGM system is paramount to successful diabetes management. The Freestyle Libre 2 and 3 CGM systems have been shown to have a Mean Absolute Difference (MAD) of 9.29 mg/dL and 8.4 mg/dL, respectively.

This indicates that the Freestyle Libre 3 has a lower MAD and is, therefore, more accurate than its previous version which have some accuracy problems

Several factors can impact the accuracy of CGM systems, including sensor location, calibration, and medication interference. Proper sensor placement and regular calibration are essential to ensuring accurate glucose readings.

If the sensor is not placed correctly at its site, the users may experience false low and false high readings. Interference from medications, such as acetaminophen, can also affect CGM accuracy, as it can cause fluctuations in glucose readings.

Therefore, it is essential for individuals to discuss any medications they are taking with their healthcare provider to ensure accurate CGM readings.


In managing diabetes, the convenience features of CGM systems can significantly enhance an individual’s experience. The Libre 3 boasts several new convenience features that are not present in the Libre 2. For instance, the Freestyle Libre 3 sensor is both smaller and thinner, making it less intrusive and more comfortable to wear.

Additionally, the Freestyle Libre 3 sensor has an extended wear time of up to 14 days, reducing the need for frequent sensor replacements.

One of the most significant convenience features of the Freestyle Libre 3 reader is the ability to scan the sensor with a smartphone app. With the blessing of this feature, you can monitor your blood glucose level without the need for a separate receiver.

This eliminates the need for additional devices, simplifying the CGM system and making it more user-friendly.

Price & recommendations

When considering the price difference between Freestyle Libre 2 and 3, it is essential to note that costs may vary depending on location and supplier.

Generally, the Freestyle Libre 3 is more expensive than its predecessor, and the price of sensors and readers can fluctuate.

Determining whether to upgrade from the Freestyle Libre 2 system to the Freestyle Libre 3 requires careful consideration of individual needs and preferences. If a CGM system with a longer sensor life is desired, the Freestyle Libre 3 starter kit may be the preferred choice to start from.

However, the Freestyle Libre 2 may be a more suitable option for individuals prioritizing cost-effectiveness. Ultimately, it is essential to weigh each system’s potential benefits and drawbacks to make an informed decision.

User feedback

The experiences of users of the Freestyle Libre 2 and 3 indicate that both CGM systems are generally well-received. Despite their popularity, some users have raised concerns about the accuracy of the readings, skin irritation at the sensor site, and difficulties in scanning the sensor.

While these issues may vary in severity and frequency depending on the individual, they are important considerations to consider when evaluating these systems.

Despite these issues, the overall user satisfaction with both the CGM systems is significantly high, with many individuals reporting that the systems have significantly improved their diabetes management and overall quality of life.

In particular, users have appreciated the ease of use, the convenience of continuous monitoring, and the reduction of fingerstick tests.
