The sensor transmits data to receiver or smartphone every few minutes, provising a dynamic picture of glucose trends. Examples includte the Dexcom G6, Abbott FreeStyle Libre serie (which is technically a flash glucose monitor but of ften grouped with CMs), and Medonic Guardisan.

Flash Glucose Monitoring (FGM)

This hybrid technology employs a sensor worn on the arm them stores glucose readings for up tu 14 days. The user scans the sensor with a reager or smartphone to get a current reading and the previous several hour of trend data. Unlike CGM, FGM does not automatically transmit data; it exets an active scan.

Dokładne: What the Numbers Mean and d What Can Go Wrong

A glucose meter is not a lab- grade instrument. International standards (ISO 15197: 2013) require meters to be considentate with in ± 15 mg / dL for values below 100 mg / dL and with in ± 15% for values at or above 100 mg / dL, at least 95% of the time. In practice, many highy -quality meters divid this standard. Still, multiple factors can degrade diseacy:

Strategic Monitoring: Making thee Most of the Data

Simply collecting numbers is nott enough. Effective diabetes management requires analyzing the data totify identify patterns andd adjuss therapy.

For those using a CGM, the key metrics included time- in- range (TIR), typically defined as 70- 180 mg / dl (3.9- 10.0 mmol / L), coefficient of variation (CV) as a mesure of glucose variability, and low glucose events below 54 mg / dL (3.0 mmol / L). These metrics are now central to personalizad diagetes care and are used in optimizing insulin pump settings and lifetimates modifics.
