What is Freestyle Libre 2 Sensor?

The Freestyle Libre 2 Sensor is a CGM system that uses a small, round sensor that is worn on the back of the upper arm for up to 14 days. The sensor is attached to a small, handheld reader or a smartphone app that displays real-time glucose readings, trends, and alerts. The Freestyle Libre 2 Sensor uses a thin, flexible filament that is inserted just under the skin and measures interstitial fluid glucose levels.

Comparison with Dexcom G6

The Dexcom G6 is another popular CGM device that uses a small, disposable sensor that is worn on the abdomen, upper buttocks, or upper arm for up to 10 days. The sensor is attached to a small, handheld receiver or a smartphone app that displays real-time glucose readings, trends, and alerts. The Dexcom G6 uses a small, flexible wire that is inserted just under the skin and measures interstitial fluid glucose levels.

Both the Freestyle Libre 2 Sensor and Dexcom G6 offer high accuracy and precision, but the Dexcom G6 has been shown to be slightly more accurate in some studies. The Freestyle Libre 2 Sensor is easier to apply and does not require fingerstick calibrations, while the Dexcom G6 requires more preparation and insertion steps. The Freestyle Libre 2 Sensor is generally less expensive than the Dexcom G6, but this can vary depending on insurance coverage and other factors.

Comparison with Medtronic Guardian Connect

The Medtronic Guardian Connect is another CGM device that uses a small, disposable sensor that is worn on the abdomen for up to 7 days. The sensor is attached to a small, handheld receiver or a smartphone app that displays real-time glucose readings, trends, and alerts. The Medtronic Guardian Connect uses a small, flexible wire that is inserted just under the skin and measures interstitial fluid glucose levels.

The Freestyle Libre 2 Sensor and Medtronic Guardian Connect have similar accuracy and precision levels, but the Freestyle Libre 2 Sensor is easier to apply and does not require fingerstick calibrations. The Medtronic Guardian Connect requires more preparation and insertion steps. The Freestyle Libre 2 Sensor is generally less expensive than the Medtronic Guardian Connect, but this can vary depending on insurance coverage and other factors.

Comparison with Senseonics Eversense

The Senseonics Eversense is a CGM device that uses a small, implantable sensor that is placed under the skin in a simple office procedure, and lasts up to 90 days. The sensor is attached to a small, handheld receiver or a smartphone app that displays real-time glucose readings, trends, and alerts. The Senseonics Eversense uses a small, flexible wire that is inserted just under the skin and measures interstitial fluid glucose levels.

The Senseonics Eversense offers high accuracy and precision levels, but it requires a minor surgical procedure to implant the sensor. The Freestyle Libre 2 Sensor is easier to apply and does not require fingerstick calibrations. The Freestyle Libre 2 Sensor is generally less expensive than the Senseonics Eversense, but this can vary depending on insurance coverage and other factors.
