Defining Flash Glucose Monitoring

How Flash Glucose Monitors Work

Te sensor in an FGM system uses an enzymebased elektrode to melyure glukose in the interstitial fluid. Te sensor is factory-calibated, meaning users do not need to perfor routine fingstick to maintain presenacy.

Traditional Blood Glucose Monitoring Methods

Traditional blood glucose monitoring, also known as self-monitoring of blood glukose, has been the foundation of diabetes self-management for decades.

Key Diferences Between Flash Glucose Monitoring and Traditional Methods

Une of the mogt concentental differences bebeween FGM and traditional BGM is the source of the glucose measurement. Traditional BGM measures glukose directlye from capillary blood, which provides a concluly real-time snapshot of the glucose concentration in the bloodstream.
