Apply the sensor
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. Most people feel no pain when applying the sensor.1
Scan Sensor
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 strip, without the need for routine finger pricks. The FreeStyle Libre system also offers software to generate concise reports to assist with the analysis of glucose data.
Get reading
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 even scan through clothing with a thickness of up to 4 mm.2
