The FreeStyle Libre sensor is applied on to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a thin, flexible and sterile fibre is inserted just under the skin. It is held in place with a small adhesive pad. In a study conducted by Abbott Diabetes Care, users agreed that inserting the sensor was no more painful than a typical finger prick test.*
To obtain a glucose reading, simply perform a quick, painless 1-second scan of the reader over the sensor. This scan gives you more information than monitoring with blood glucose test strips, without the need for routine finger pricks.1 The FreeStyle Libre system also offers FreeStyle Libre software to generate concise reports to assist with the analysis of glucose data.
Each scan of the reader over the sensor gives a current glucose reading, the last 8-hours of glucose history, and a trend arrow showing if glucose is going up, down, or changing slowly. The reader can scan through clothing5.

The FreeStyle Libre sensor's small size (similar to a £2 coin) makes it discreet to wear.
This small water resistant2 sensor is worn on the back of your upper arm and lasts for up to 14 days.
Unlike traditional blood glucose monitoring, using the FreeStyle Libre sensor does not involve routine finger pricks.1
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.
It continuously measures the glucose concentration in your interstitial fluid, and stores 8 hours of data.
Finger prick blood glucose readings and sensor glucose readings won’t always match and in fact are likely to be different.3
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.4
1 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 levels or if hypoglycaemia is reported by the system or when symptoms do not match the systems readings.
2 The sensor is water-resistant in up to 1 meter of water. Do not immerse longer than 30 minutes.
