The Libre 3 and Libre 2 are two continuous glucose monitoring (CGM) systems developed by Abbott Diabetes Care. Both systems are designed for people with diabetes to help manage their blood sugar levels. Here's a detailed comparison of the two devices:
Sensor Size and Accuracy:
The Libre 3 sensor is the smallest and most accurate sensor on the market, with a weight of just 0.035 ounces and a diameter of 0.83 inches. In clinical studies, the FreeStyle Libre 3 sensor achieved an overall mean absolute relative difference (MARD) of 7.9%, which is the smallest difference observed between laboratory blood glucose measurements and results given by the CGM. This makes it the most accurate CGM available.
App and Notification Compatibility:
The Libre 3 app is compatible with certain mobile devices and operating systems, such as iOS and Android. It connects to the Libre 3 sensor wirelessly, allowing for real-time葡萄糖监测. This means you'll get a reading every minute and won't need to scan the sensor to see your latest blood sugar levels.相比之下, the Libre 2 app is only compatible with certain mobile devices and operating systems and requires manual scanning of the sensor.
Warm-up Time:
Both the Libre 2 and Libre 3 sensors require a warm-up period of 60 minutes after application. However, the Libre 3 has a slightly smaller sensor size that is easier to insert and may be less intrusive.
Insertion Device:
The Libre 3 comes with an all-in-one insertion device that makes it easier to insert the sensor compared to the Libre 2 sensors, which need to be loaded into an applicator before insertion.
Sensor Lifespan:
Both sensors last for 14 days, with an additional 12-hour grace period in case of sensor drift.
Glucose Reading Frequency:
The Libre 3 provides continuous glucose readings every minute, which can be less distracting than the occasional scanning of the sensor in the Libre 2 system.
User Experience and Satisfaction:**
Both the Libre 2 and Libre 3 systems have been well-received by users, with high satisfaction rates reported regarding ease of use and availability of features. While some users have reported issues with the low glucose alarm on the Libre 3, these have generally been addressed in subsequent app updates.
Cost:
The cost of the Libre 3 system is slightly lower than the Libre 2 system, with the price of two sensors (28 days) being around $150 compared to around $170 for the Libre 2.
It's important to note that the decision between the Libre 2 and Libre 3 should be based on personal preference and individual needs, as both systems have their advantages and disadvantages. Additionally, the specific features and compatibility of each system may vary depending on the country and region where it is being sold., the Libre 3 offers a more compact design, continuous葡萄糖 monitoring, and ease of use compared to the Libre 2. However, the Libre 2 is still a reliable and accurate system capable of providing valuable insights into daily glucose patterns. Ultimately, both systems can be suitable for managing diabetes, and it's important to choose the one that best suits your lifestyle and medical needs.
