This innovative sensor provides continuous, automatic measurement of glucose levels in the interstitial fluid, offering valuable insights for effective self-management of diabetes.

Key Features

• 14-Day Wear: Each sensor is designed for up to 14 days of continuous use, providing long-term monitoring with minimal hassle.
• Discreet Size: The sensor is small and discreet, approximately the size of two stacked quarters, and is worn on the back of the upper arm.
• Water Resistance: With water resistance up to 1 meter for 30 minutes, it remains functional during daily activities such as swimming and showering.
• No Routine Fingersticks: Eliminates the need for routine fingerstick calibration, though fingersticks may be necessary if readings do not align with symptoms.
• Factory-Calibrated: Ready to use with no user calibration required, simplifying the setup process.

Connectivity and Alerts

• Real-Time Alerts: Provides optional alarms for high and low glucose levels and signal loss, enhancing safety and awareness.
• Data Access: Compatible with the FreeStyle Libre 2 Reader and the FreeStyle LibreLink app, allowing easy access to glucose data via NFC and Bluetooth.

• Removal: Easily removed by peeling up the adhesive edge; baby oil or adhesive remover can assist if needed.
• Precautions: Should be removed before MRI, CT, or X-ray procedures to prevent interference.

Performance and Benefits

• Accuracy: Demonstrates a mean absolute relative difference (MARD) of approximately 9.3–9.7% over 14 days, with performance improving after the first day.
• Trend Information: Provides comprehensive glucose trend information and alerts, reducing the need for routine blood glucose testing strips.
• Lifestyle Integration: Suitable for various activities, supporting flexible diabetes management and potentially improving glycemic control.

Storage and Handling

• Storage Conditions: Should be stored between 4°C and 25°C, away from direct sunlight.
• Interference: High doses of vitamin C may affect readings, but no interference from acetaminophen is noted.

The FreeStyle Libre 2 Sensor stands out as a reliable and convenient tool for individuals managing diabetes, offering comprehensive glucose monitoring with minimal disruption to daily life.
