Continuous glucose monitoring (CGM)
Continuous glucose monitoring (CGM) is a powerful tool in helping people with diabetes achieve better glucose levels. Two types of CGM systems are currently available: real‐time (rtCGM) and intermittently scanned CGM (isCGM), also called flash glucose monitoring, each of which measure glucose in the interstitial fluid. rtCGM systems measure glucose every few minutes and actively transmit data wirelessly from the sensor to a reader or smartphone app, whereas isCGM systems transmit data only when the user scans their sensor with a reader or smartphone app.
