Traditional Fingerstick Blood Glucose Monitoring

Fingerstick testing - using a lancet to crich the fingertip, appliying blood to a tett strip insert into a glucose meter - has been the standard for decades. Despite the adventure of newer technologies, it contains widely used due te ts low coss, simplicy, and decades of clinical revidence.

Systemy monitorowania Glukozy (CGM)

CGMs continuous stream of glucose readings every 1- 15 minutes, generating trend graphs, alerts, and actionable insights.

How CGM Works

A thin sensor filament is inserted just undeid the skin (usually one thee abdomen, arm, or buttock), measuring glucose concentration in the interstitial fluid - the fluid surrounding cells. Glucose diffuses frem blood capillaries into interstitial fluid with a time lag of 5- 15 minutens, which modern CGMs account for altillythmically. The sensor is connevenevted to a transmitter that wirelessly sendats a ta a receiver, sphone, or both. Sensors.
