Do not ignore symptoms that may be due to low or high blood glucose. If you have symptoms that do not match the Sensor glucose reading or suspect that your reading may be inaccurate, check the reading by conducting a finger stick test using a blood glucose meter. If you are experiencing symptoms that are not consistent with your glucose readings, consult your health care professional.

How is the FreeStyle Libre system calibrated?

The FreeStyle Libre system is a factory-calibrated Sensor that has been proven to safely and successfully replace routine self-monitoring of blood glucose (SMBG) and deliver important clinical benefits.1 Specific details about our calibration process are proprietary.
