The FreeStyle Libre 3 system has the crown for being the world’s smallest CGM sensor. These sensors are fully smartphone compatible but offer readers for those who prefer. To answer a common question, ‘Can FreeStyle Libre 3 Reader Use Test Strips?’, yes, the Libre 3 reader is compatible with the test strips. Although this system gained trust and love, the newer ones come with more advanced technology – the latest CGM systems by Abbott in the US are Freestyle Libre 3 Plus and Freestyle Libre 2 Plus.
Understanding the FreeStyle Libre 3 Sensor & Reader
The FreeStyle Libre 3 system comprises two main components:
- FreeStyle Libre 3 Sensor: A small, discreet sensor inserted on the back of the upper arm. With the help of a micro pin, this sensor detects your glucose levels continuously from interstitial blood and transmits the data to your Libre app or the reader, whichever you are using.
- FreeStyle Libre 3 Reader: A handheld device (optional) that scans the sensor to display glucose readings.
While the sensor can transmit data directly to a smartphone via the FreeStyle Libre 3 app, the reader serves as an alternative for those who prefer a dedicated device.
Compatibility Between FreeStyle Libre 3 Reader and Test Strips
The FreeStyle Libre 3 reader is equipped with a built-in blood glucose meter designed to be used exclusively with FreeStyle Precision Neo blood glucose test strips. It does not support ketone testing, and using other test strips may result in errors or the meter not functioning properly.

Conclusion

Monitoring blood sugar does not even require a reader as the Libre 3 sensors are fully compatible with the LibreLink app. Last but not least, the Freestyle Libre 3 reader is compatible with the Freestyle Libre 3 Plus sensors in the USA.
