Does the FreeStyle Navigator system require calibration?
Yes. The system needs to be calibrated to finger-stick blood glucose measurements. The system contains a built-in FreeStyle® Blood Glucose Meter for convenient calibration and confirmatory blood glucose tests. The system has to be calibrated on average only 4 times during the entire 5-day wear period. The system requires calibration at approximately 10, 12, 24 and 72 hours after sensor insertion. You will not see any continuous glucose readings until the first calibration is completed successfully. When the conditions are not conducive, the system automatically prevents calibration so that it can maintain glucose measurement accuracy.
