Features to Consider When Buying a Glucose Meter

Touchscreens, intuitive menus, and color-coded feedback make daily monitoring easier.

✔️ Data Storage & Connectivity

Bluetooth syncing, mobile apps, and cloud storage help you track and share your data with doctors.

✔️ Cost of Supplies

Meter prices are often low—but the real cost lies in the test strips and sensors. Factor in monthly supply expenses.

✔️ Portability

If you’re often on the go, opt for a compact model with a durable case.

Insurance and Prescription Considerations

CGMs like the Dexcom G7 and Freestyle Libre 3 often require a prescription and prior authorization.
Insurance may cover the cost of meters and test strips, especially for those with Type 1 diabetes or insulin dependence.
Always check with your provider to determine what’s covered under your health plan.
