Continuous Glucose Monitor Buying Guide

Choosing between continuous glucose monitors and traditional meters requires understanding your specific needs, lifestyle, and budget constraints. This guide breaks down the key factors our team evaluated during three months of testing.

CGM vs Traditional Meter: Which Do You Need?

Continuous glucose monitors provide 24/7 data through wearable sensors, revealing patterns impossible to capture with finger-stick testing alone. Traditional meters deliver instant snapshots at specific moments, requiring conscious testing decisions.

CGMs excel for people wanting comprehensive glucose pattern understanding, including response to meals, exercise, sleep, and stress. The real-time trending data helps prevent highs and lows before they become dangerous.

Traditional meters suit users preferring simplicity, lower ongoing costs, or those supplementing CGM data with calibration checks. Many people use both: CGMs for pattern insights and meters for confirmation testing.

Understanding MARD Accuracy

MARD (Mean Absolute Relative Difference) measures how closely CGM readings match lab reference values. Lower percentages indicate better accuracy. Leading CGMs achieve MARD scores between 8-9%, while traditional meters typically range 5-10% depending on brand and conditions.

During our testing, we found that real-world accuracy varies based on sensor placement, hydration, and rapid glucose changes. No device matches lab precision perfectly, but clinical-grade CGMs provide sufficient accuracy for informed decision-making.

Insurance Coverage and Costs

Prescription CGMs like Dexcom G7 and FreeStyle Libre systems often receive insurance coverage for diagnosed diabetics. Over-the-counter options like Stelo and Lingo require out-of-pocket payment but offer HSA/FSA eligibility.

Traditional meters typically cost less upfront but require ongoing test strip purchases. Calculate long-term costs when comparing options. A $20 meter with $1 strips eventually exceeds a $100 meter with $0.50 strips.

Smartphone and Smartwatch Compatibility

Modern glucose monitors integrate with smartphone apps for data tracking, trend analysis, and sharing with healthcare providers. Apple Health and Google Health Connect compatibility lets you consolidate glucose data with fitness, nutrition, and sleep metrics.

Some CGMs offer direct smartwatch display, letting you check glucose without retrieving your phone. During workouts or meetings, this convenience proves valuable. Check compatibility with your specific devices before purchasing.

Sensor Wear Time and Waterproofing

CGM wear times range from 10 to 15 days depending on model. Longer wear times reduce sensor replacement frequency and cost per day. The Stelo’s 15-day duration currently leads the OTC market.

Waterproofing ratings determine whether swimming, showering, or heavy sweating requires sensor protection. Fully waterproof sensors like the Stelo eliminate lifestyle restrictions that adhesive patches and shower covers impose.

Adhesion and Skin Sensitivity

Sensor adhesion challenges many CGM users, particularly during exercise or hot weather. Our forum research identified skin irritation as the top complaint among long-term users. Hypoallergenic adhesives and overpatch tapes help sensitive individuals tolerate continuous wear.

Rotating insertion sites prevents scarring and lipohypertrophy. Most manufacturers recommend specific body locations for optimal accuracy and comfort. Experiment with placement to find your optimal sites.
