Practical considerations for daily operation.
Designed to slot into a typical daily-use routine without friction.
Plan a short learning curve to get a feel for the device's prompts and ideal positioning.
Keep the unit clean and store it in a dry case to preserve accuracy long-term.
Best kept on a counter or shelf at home; not engineered for daily commuting.
Works fully offline — every key reading is visible on the device itself, no phone required.
For context: continuous glucose monitoring (CGM) has largely replaced standalone glucometers as the primary monitoring tool in T1D — the Dexcom G7 provides a reading every 5 minutes, trend arrows, and alarms without finger pricks. The G7 achieves 8.2% MARD (mean absolute relative difference) — more accurate than most glucometers. Used alongside a backup fingerstick glucometer for hypoglycemia verification, CGM is the current standard of care for T1D. Prescription required; covered by most insurance for T1D.

The Dexcom G7 gives a reading every 5 minutes, plus trend arrows and alarms, without finger pricks. It reaches 8.2% MARD (mean absolute relative difference), more accurate than most glucometers. Paired with a backup fingerstick glucometer to confirm lows, CGM is the current standard of care for T1D. It requires a prescription and is covered by most insurance for T1D.
