Sensor Freestyle Libre

14-day sensor

No calibration needed7


Continuously measures glucose day and night8

Scans through clothing9


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.


To obtain a glucose reading, simply perform a quick, painless3 1-second scan of the app over the sensor.
This scan gives you more information than monitoring with blood glucose test strips, without the need for finger pricks1.


Each scan 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.

Choosing the site

Select an area on the back of your upper arm, avoiding areas with moles, scarring, or recent insulin injections. Select a different site than the one most recently used.

Preparing your skin

Clean the skin with soap and water, dry the skin, wipe skin with an alcohol swab (let it air-dry) before proceeding. The site selected on the back of the upper arm should be clean-shaven.

Applying the sensor

The sensor pack and sensor applicator are packaged as a set.
