Introduction
If you are living with diabetes, continuous glucose monitoring (CGM) can be a Great Help. It assists you keep track of your blood sugar levels around the clock, giving you the information you need to make informed decisions about your health. The Freestyle Libre 2 and Freestyle Libre 3 are two glucose monitoring systems designed to help diabetic patients manage their condition. Both systems are made by Abbott and are similar in many ways, but there are also some key differences that set them apart.
In this article, we’ll take a closer look at the features, accuracy, cost, and overall performance of the Freestyle Libre 3 vs 2
After Reading this article you will be able to figure out which CGM Device is best Fit for you
Let’s Start
What is the difference between Freestyle libre 2 vs 3?
Freestyle Libre 3 has real-time alarms & alerts, while Freestyle Libre 2 requires physical scanning to view glucose readings.
Let’s, Deep Dive into more Depth of the article
Features & benefits
One of the key differences between the two systems is that the Freestyle Libre 3 has a built-in sensor that continuously measures glucose levels and sends the data to a reader device. On the other hand, Freestyle Libre 2 requires the user to manually scan the sensor with a reader device to obtain glucose readings.
This means that the Freestyle Libre 3 reader provides more real-time and accurate glucose readings, while the Freestyle Libre 2 may need to be more accurate and convenient.
The Freestyle Libre 3 also has a new feature called “Smart Alerts,” which sends an alert when glucose levels are predicted to reach a high or low level in the next 30 minutes. This feature is not available on the Freestyle Libre 2.
Freestyle Libre 2
Continuous glucose monitoring (CGM) system that provides real-time glucose readings
- The small and discreet design allows for easy wear and mobility
- 14-day sensor life
- Easy-to-read, color display
- Alarm feature for high and low glucose alerts
- Automatic data storage for up to 90 days
- Mobile app compatible
Freestyle Libre 3
- Continuous glucose monitoring (CGM) system that provides real-time glucose readings
- Real-time updates, no need to scan
- Pre-applied applicator for sensor
- Advanced sensor and continuous updates
- Predicts unusual glucose levels 30 minutes prior
- The small and discreet design allows for easy wear and mobility
- 14-day sensor life
- Easy-to-read, color display
- Alarm feature for high and low glucose alerts
- Automatic data storage for up to 90 days
- Mobile app compatible
Adds new features such as a 3-hour historical glucose trend graph, customizable high and low glucose alerts, and automatic data transfer via Bluetooth to the mobile app
However, Freestyle Libre 3 adds several new features, such as the 3-hour historical glucose trend graph, customizable high and low glucose alerts, and automatic data transfer via Bluetooth to the mobile app.
Accuracy & user experience
In terms of accuracy, the Freestyle Libre 2 and Freestyle Libre 3 are highly accurate in clinical trials, with errors typically within 10-15% of a traditional fingerstick measurement. The Freestyle Libre 3 is also equipped with a more advanced sensor that uses a different method of glucose measurement, resulting in improved accuracy and faster response times compared to the Freestyle Libre 2
The Freestyle Libre 2 had a mean absolute difference (MAD) of 9.4 mg/dL, and the Freestyle Libre 3 had a MAD of 8.4 mg/dL. This means that both systems have a very high level of accuracy in tracking glucose levels.
The Freestyle Libre 2 and 3 are continuous glucose monitoring (CGM) systems worn on the body to measure and track glucose levels. Both systems use a small sensor placed under the skin and a reader device to access the glucose readings.
The Freestyle Libre 3 has improved accuracy and a longer wear time than the Freestyle Libre 2. Both systems are user-friendly and have received positive feedback from users for their ease of use and ability to help manage diabetes
How to use Freestyle Libre sensors
To use the Freestyle Libre 2 or 3 continuous glucose monitoring (CGM) systems, follow these steps:
Insert the sensor: Clean and dry the area where you want to insert the sensor. Take the sensor out of the packaging and insert it under the skin on your abdomen, upper arm, or thigh.
Start the sensor: Once inserted, use the reader to start the sensor and establish a connection.
Check glucose readings: Use the reader to check your glucose levels. You can also use the Freestyle Libre smartphone app to view your glucose levels and trend information.
Replace the sensor: The Freestyle Libre sensor should be replaced after 14 days, as it provides more accurate results till this duration.
Note: Before using either device, carefully read and follow the instructions in the product manual. Consult with your healthcare provider if you have any questions or concerns.
Pricing & recommendation
Talking about freestyle libre 2 vs 3 in terms of pricing both have different prices depending on the country and the supplier. However, the Freestyle Libre 3 sensor is generally more expensive than the Freestyle Libre 2. The cost of the sensors and readers also varies depending on the country and the supplier
Should you upgrade from the Freestyle Libre 2 to the Freestyle Libre 3? The answer to that question depends on your specific needs and preferences.
If cost is a major concern for you, the Freestyle Libre 2 may be the better option
Conclusion
The Freestyle Libre 2 and 3 are continuous glucose monitoring systems made by Abbott. Both are quite similar in many aspects, however there are some differences. The Freestyle Libre 3 has a built-in sensor that measures glucose levels continuously and offers a 3-hour historical trend graph, alerts, and Bluetooth transfer to a mobile app.
The Freestyle Libre 2 requires manual scanning and lacks these features. Both are accurate with similar MAD levels. The choice between the two depends on user needs and preferences.
