Freestyle Libre Sensor
The days of routine glucose testing with lancets, test strips and blood are over.
Welcome to flash glucose monitoring!
Flash Glucose Monitoring enables you to test your glucose levels without routine pricking your finger*. The small sensor automatically measures and continuously stores glucose readings day and night.
Unlike current blood glucose meters, the FreeStyle Libre Sensor measures the glucose in the body’s interstitial fluid. You need a FreeStyle Libre Reader or have the FreeStyle LibreLink app on your phone to use the Sensor.
The FreeStyle Libre Sensor’s small size makes it discreet to wear. It is worn on the back of your upper arm and lasts for up to 14 days.
The Sensor has a small, flexible tip that is inserted just under the skin.
Unlike traditional blood glucose monitoring, using the FreeStyle Libre sensor does not involve painful routine finger pricks. You can scan as many glucose readings as you want whilst the sensor is being worn – it even scans through clothes!
It continuously measures the glucose concentration in your interstitial fluid, and stores 8 hours of data. This means that for a complete glycaemic picture, you only need to scan once every 8 hours– enabling you to make more informed decisions about how you manage your diabetes.
Finger prick blood glucose readings and sensor glucose reading won’t always match and in fact are likely to be different. That’s the interstitial fluid (ISF), a thin layer of fluid that surrounds the cells of the tissues below your skin, not from your blood. There is a 5 to 10 minute delay in ISF glucose response to changes in blood glucose. Glucose readings on ISF have been proven to reliably reflect glucose levels.
The FreeStyle Libre sensor is water-resistant and can be worn on the back of your arm for up to 14 days whilst you shower, bathe, swim, exercise or play.
You do not need to calibrate the FreeStyle Libre sensor with a finger prick. As it is made by a process which means the sensitivity of the sensors vary very little – it is calibrated at the factory.
Although results on the FreeStyle Libre reader can quickly and easily give you the answers you have been looking for, uploading your results on to LibreView enables you to save more than the 90 days of data available on the FreeStyle Libre reader and then remotely share this with your Healthcare Professional.
The LibreView system gives you intuitive reports to help you discover patterns and trends so you can make informed decisions about your diabetes.
Whilst we know that every hour and every day is different, the Glucose Patterns Insights report in LibreView enables you to view your average day and estimated HbA1c at a glance.

*A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycaemia or impending hypoglycaemia is reported by the system or when symptoms do not match the system readings. For a complete glycaemic picture, scan the sensor once every 8 hours.
