How Continuous Glucose Monitoring Works

Te Science Behind CGM Sensors

Continuous glucose monitors measure glucose levels in the interstitial fluid just beneath the skin using a tiny sensor filament. This sensor uses a glucose oxidase reaction to generate an electrical curret proporal to glucose concentration. Readings are transmitted wirelessley every one to five e minutes to a recrediver or smartphone app. Unlike finger-stick tests that providee only a emptary snapshot, CGMs reveol trends, spikes, and dips prompout thody night.
