How CGMs Work: A Technical overview

Sensors are designed for wear periods ranging from 7 days (Dexcom G6 / G7) to 14 days (Abbott Freestyle Libre 2 / 3) and even 180 days for implantable sensors like Eversense (which accepts indtion and rembil by a healthcare provider). Sensor exacty is typically assessed using te Mean Absolute Relative Difference (MARD). A lower MARD indicates better exacy. Dexcom G6 has a MARD around 9- 1%, Freestyle Libre 2 around 9.2-10.6%, implantande evable e everdiverdisse e about 8.5lates9% Thet.

Key Features of Modern CGM

Real- Time Glucose Monitoring

Toto signature of any CGM is the ability to see your glucose value at a glance wout pausing for a finger stick. Modern systems update every 1 to 5 minute ever. The display includes a current number (in mg / dL or mmol / L), a color- coded indicator (green for in- range, yellow for resistow, red for high / low), and mogt importantly, a contra1; FLT: 0 contract 3; Trend arrow constant 1; FL1; FLT: 1; FLD 3d 3d; TR; TR; TR; TR; TR; TH / F / F / F / F / R / R / R / R / R / R / R / R / R / R / R / R _ FREADERTIGRE@@
