Freestyle Libre 3 Sensor (Expire Date 31.03.2026)
The FreeStyle Libre 3 system is a continuous glucose monitoring (CGM) device designed to track glucose (sugar) levels in people with diabetes in real time. It measures glucose every minute and automatically sends those readings to your smartphone or a dedicated reader without manual scanning.
How It Works
-
A small sensor is worn on the back of the upper arm, where a tiny thread-like filament sits just under the skin. This reads glucose in the interstitial fluid (just under the skin) instead of direct blood sampling.
-
Once applied with an applicator, it continuously monitors glucose 24/7 without regular finger pricks.
Key Features
-
Real-Time Monitoring: Sends glucose values automatically every minute to your smartphone app or reader.
-
No Routine Scanning: Unlike older Libre versions, readings are streamed continuously — no active scanning required.
-
Small, Discreet Sensor: One of the smallest and most discreet sensors on the market.
-
Wear Time:
-
Standard Libre 3 sensor: up to ~14 days wear.
-
Libre 3 Plus sensor extends that to up to 15 days and allows use from age 2.
-
-
Alarms & Trends: Optional push-notifications for high/low glucose and trend arrows in the app.
-
Data Sharing: You can share glucose trends with family or healthcare teams via apps and cloud platforms.
