Co je to za Glucose Monitor (CGM)?

A Continuous Glucose Monitor is a varable device that measures glucose levels in the interstitial fluid - the fluid between cells - at frequent intervenls, typically every one to five minutes. This real-time tracking enables users to see not only their current glucose value but also te direction and rate of change, empowering them to take proactive steste to maintain stable levels.

How CGM Measure Glucose: Technologie a Accuracy

CGMs measure glucose indirectly. Instead of testing capillary blood like traditional meters, thae sensor analyzes interstitial fluid, which has a slight time lag (approatetyle 5-15 minutes) compared to blood glucose. This is not usually a problem for trend monitoring, but it 's important for users to understand when interpreting rapid changes. The sensor' s working elektrode is coated with glucomers oxide, an enzyme that converts glucosose oxygen glucox oxygen glucolux hydroged peroxide.

Accuracy is expressed as Mean Absolute Relative Difference (MARD); Thee average percent difference between CGM readings and reference blood glucose values. Modern CGM equipment es around 8-10%, which is consided sufficient for making reaterment decisions.
