The FreeStyle Libre 3 Plus sensor is factory-calibrated and does not require, or allow for, manual calibration. If you believe your sensor glucose readings are inaccurate or don’t align with how you feel, perform a blood glucose test to confirm the readings and treat based on that result. If the issue persists, consider replacing your FreeStyle Libre 3 Plus sensor.

For any questions or troubleshooting related to your FreeStyle Libre 3 Plus sensor calibration, please contact Abbott Customer Service for assistance.

Always refer to the user guide for important safety information and detailed step-by-step instructions on your t:slim X2 pump.
