The FreeStyle Libre sensor’s small size (similar to a £2 coin) makes it discreet to wear.
This small water resistant₸ sensor is worn on the back of your upper arm and lasts for up to 14 days.
NO MORE ROUTINE FINGER PRICKS
Unlike traditional blood glucose monitoring, using the FreeStyle Libre sensor does not involve routine finger pricks.†
Additionally, the FreeStyle Libre sensor is made by a process which means the sensitivity of the sensors vary very little. This means that is calibrated at the factory – so you don’t need to calibrate it again using a finger prick.1,3
It continuously measures the glucose concentration in your interstitial fluid, and stores 8 hours of data.
TRADITIONAL BLOOD GLUCOSE TESTING OR FLASH GLUCOSE MONITORING?
Finger prick blood glucose readings and sensor glucose readings won’t always match and in fact are likely to be different.1
Sensor glucose readings come from the interstitial fluid (ISF), a thin layer of fluid that surrounds the cells of the tissues below your skin. There is a 5 to 10 minute delay in ISF glucose response to changes in blood glucose.2

* Scanning the sensor does not require lancets.
Φ For a complete glycaemic picture, scan once every 8 hours.
‡ 60-minute warm-up required when applying the sensor
~ Daily Patterns need at least 5 days of glucose data
Ω The Reader can capture data from the sensor when it is within 1cm to 4cm of the sensor.
Θ The Glucose Trend Arrow may not always appear with every reading.
₸ Sensor is water resistant in up to 1 metre (3 feet) of water for a maximum of 30 minutes. Do not immerse longer than 30 minutes. Not to be used above 10,000 feet.
† 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.
Ѱ For children aged 4-12, a caregiver at least 18 years old is responsible for supervising, managing, and assisting them in using the FreeStyle Libre system and interpreting its readings.
◊ The FreeStyle LibreLink app and the FreeStyle Libre reader have similar but not identical features. 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 FreeStyle LibreLink app or when symptoms do not match the app readings. The FreeStyle Libre sensor communicates with the FreeStyle Libre reader that started it or the FreeStyle LibreLink app that started it. A sensor started by the FreeStyle Libre reader will also communicate with the FreeStyle LibreLink app. The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check the Smartphone Compatibility Guide before using the app. Use of FreeStyle LibreLink requires registration with LibreView.
