DexCom recommends calibrating its continuous glucose monitoring (CGM) system based on the specific model being used. For the DexCom G6, calibration is not required, as it is designed to provide accurate readings without any calibration needed. However, if users experience any unusual readings or symptoms, they are encouraged to perform a fingerstick test for verification. For earlier models, such as the DexCom G5, users were advised to calibrate the device at least twice daily, typically using fingerstick blood glucose values to ensure the accuracy of the readings. It is always helpful to consult the user manual or the specific information provided with the device to understand any calibration needs and best practices. For the most up-to-date details, it is advisable to check the official DexCom website, where you can also find contact information if further assistance is needed.
