Is it okay if my Dexcom G4 PLATINUM CGM sensor glucose readings and fingerstick blood glucose values don’t match exactly?
Yes. Your sensor glucose readings are meant to be used for trending only. Your blood glucose meter and sensor measure your glucose from two different types of body fluids: blood and interstitial fluid. Therefore, the values from your blood glucose meter and sensor may not match exactly. Contact the Dexcom Product Support team for further assistance by calling 1-877-339-2664.
