How accurate is the Dexcom G6 compared to FreeStyle Libre?

Both continuous glucose monitors provide reliable readings, but there are some differences to keep in mind.

Sensor-based devices like both Dexcom G6 and FreeStyle Libre can be slightly less accurate when your blood sugar is very high or very low compared to traditional finger-stick testing. Studies have shown that CGM sensors may not be as precise at extreme glucose levels.

If either device gives you an unusual or unexpected reading, it's a good idea to confirm it with a traditional finger stick to be safe.

Tips for getting started with Dexcom G6:

* Check the manufacturer's website for detailed instructions and setup videos
* Give yourself time to adjust to wearing the sensor and interpreting the data
* Don't hesitate to contact Dexcom support or ask your healthcare provider if you have questions about readings
* Remember that CGMs show trends, which can be just as helpful as individual numbers

Many people find that switching between CGM brands takes a little adjustment, but the technology behind both is quite similar. You'll likely adapt quickly to the Dexcom interface.
