Frequently Asked Questions
Should I make treatment decisions based on the results from my Dexcom G4
PLATINUM CGM system?
No.Treatmentorinsulindosingdecisionsshouldbebasedonthebloodglucosevaluefrom
yourbloodglucosemeter.Thedirection,rateofglucosechange,andtrendgraphonyour
DexcomG4PLATINUMSystemprovideadditionalinformationtohelpwiththesedecisions.
Is it okay if my Dexcom G4 PLATINUM CGM sensor glucose readings and
ngerstick 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uids:bloodand
