Glu-Chek’s CGM system uses advanced biosensing technology to deliver reliable real-time data, but understanding how calibration and accuracy work can help users gain full confidence in the results.

What Is Calibration and Why Is It Important?

Sensor calibration ensures that glucose readings from your interstitial fluid closely match blood glucose levels. Glu-Chek CGMs are factory-calibrated, meaning most users don’t need to perform manual calibration. However, you can recalibrate if prompted by your device or if readings seem inconsistent.

Factors That Affect Accuracy

• Hydration levels: Dehydration may affect sensor readings.
• Sensor placement: Always follow placement guidelines.
• Compression lows: Lying on the sensor can temporarily reduce readings.
• High body temperature: Fever or intense physical activity can create variability.

How Glu-Chek Ensures Accuracy

Our CGMs undergo rigorous ISO and CE-compliant testing. Algorithms use AI to filter noise and provide highly stable data, making Glu-Chek’s sensors comparable to top brands like Dexcom and FreeStyle Libre.

Reminder: If you experience symptoms that don’t match your CGM reading, perform a finger-prick test for confirmation and consult your healthcare provider.
