Introduction:

The Freestyle Libre 3 and Libre 2 are two popular Continuous Glucose Monitoring (CGM) devices from Abbott. While both devices have similar features, there are some key differences between them. In this article, we will compare Freestyle Libre 3 and Libre 2 and explore the differences between the two devices. We will also discuss the price difference between Freestyle Libre 3 and Libre 2.

Overview of Freestyle Libre 3 and Libre 2:

Freestyle Libre 3 and Libre 2 are both CGM devices that allow people with diabetes to monitor their glucose levels continuously. The devices consist of a small sensor that is inserted under the skin and a reader that can be used to scan the sensor. The sensor measures glucose levels in the interstitial fluid, which is the fluid that surrounds the cells in the body.

Difference in Sensor Size:

One of the key differences between Freestyle Libre 3 and Libre 2 is the size of the sensor. Freestyle Libre 3 has a smaller sensor size compared to Libre 2, making it more comfortable to wear. The sensor of Freestyle Libre 3 is 60% smaller than Libre 2, and it is also thinner and more flexible.

Battery Life and Charging Time:

Freestyle Libre 3 has a longer battery life compared to Libre 2. Freestyle Libre 3 can last up to 14 days, while Libre 2 can last up to 10 days. Freestyle Libre 3 also has a shorter charging time. The device can be fully charged in just two hours, while Libre 2 takes three hours to charge fully.

Scanning Distance and Speed:

Freestyle Libre 3 has a longer scanning distance compared to Libre 2. Freestyle Libre 3 can be scanned from a distance of up to 4cm, while Libre 2 can be scanned from a distance of up to 1.5cm. Freestyle Libre 3 also has a faster scanning speed. The device can provide glucose readings in just one second, while Libre 2 takes about four seconds to provide glucose readings.

Price Comparison:

Freestyle Libre 3 price and the price of Libre 2 depend upon various factors such as insurance and country. However, it is important to note that the cost of the device may be covered by insurance, and there may also be cost savings associated with the longer battery life and shorter charging time of Freestyle Libre 3.

Conclusion:

Freestyle Libre 3 and Libre 2 are both effective CGM devices that can help people with diabetes to manage their condition more effectively. The main differences between the two devices are the size of the sensor, battery life, charging time, scanning distance, and scanning speed. While the price of Freestyle Libre 3 is higher than Libre 2, the longer battery life and faster charging time of the device may provide cost savings in the long run. Ultimately, the choice between Freestyle Libre 3 and Libre 2 will depend on personal preferences and individual needs.
