What to Look for When Buying a Blood Glucose Meter
Accuracy Standards
Always verify your meter carries ISO 15197:2013 certification. Meters sold on MDS Diabetes are pre-screened for this standard, giving you confidence in every reading.
Ongoing Strip Costs
A cheap meter means nothing if strips cost $1 each. Calculate your monthly strip spend based on how often you test — typically 2–4 times daily for Type 2 and up to 10 times for Type 1 patients.
Connectivity and Data Sharing
Bluetooth-enabled meters sync readings directly to apps like mySugr, LibreView, or Apple Health, making it easy to share data with your healthcare team at appointments.
