The FreeStyle Libre 2 System

The FreeStyle Libre 2 system eliminates the need for painful routine finger pricks offering an easy way to check glucose with a painless1 1-second scan even through clothingΩ. Now with optional alarms to let your patients know when their glucose is too high or too low.

The small, discreet sensor worn on the back of the upper arm continuously measures the glucose concentration in the body's interstitial fluid. It is worn for up to 14 days and is water-resistant so continues to work while your patients shower, swim or exercise.

People with diabetes can use the FreeStyle Libre 2 reader or FreeStyle LibreLink app to scan their FreeStyle Libre 2 sensor and receive their glucose levels and optional alarms. For a complete glycaemic picture, they must scan the FreeStyle Libre 2 sensor every 8 hours.

How the FreeStyle Libre 2 System works

In 3 simple steps, your patient can get their glucose readings.

Step 1 - Apply

The FreeStyle Libre 2 sensor is applied on the back of the arm using the applicator. Most FreeStyle Libre system users have reported that applying the sensor was painless1

Step 2 - Scan

With the FreeStyle Libre 2 reader or FreeStyle LibreLink app, users will scan their sensor to see their glucose readings

Step 3 - Read

Users will see their current glucose reading, 8-hours of data and a trend arrow that shows where their glucose is heading.

FreeStyle Libre 2 - With all the features your patient already loves in the FreeStyle Libre system - and much more

The FreeStyle Libre system is the #1 sensor-based glucose monitoring system used worldwide2



The sensor is easily attached to the back of the upper arm. It can be worn up for 14 days.



Excellent accuracy overall and even in the low glucose range, when it matters the most.3,4



Your patient can check their glucose anytime, anywhere with a simple 1-second scan even through clothing.Ω 



The new optional glucose alarms can be set individually according to your patients needs.



Free from finger pricks to dose insulin. Free from finger pricks to confirm hypo or impending hypo. Free from finger pricks when glucose is rapidly changing.


With glucose alarms, rest assured your patients will know when their glucose levels are too high or too low


Your patient can automatically ** receive an alarm when their glucose is too low or too high


Your patient can scan the FreeStyle Libre 2 sensor to see their glucose reading, trend arrow, and 8-hour history


They can use the information to take appropriate action and manage their diabetes as needed



With every painless1 scan the FreeStyle Libre 2 reader or FreeStyle LibreLink app, displays the current glucose reading, the latest 8 hours of continuous glucose data and a trend arrow showing if glucose levels are going up, down, or changing slowly.



Current glucose reading

Based on the most recently updated glucose value 
(1 minute)


Trend arrow

The trend arrow shows the direction glucose is heading, along with the rate of change


8-hour history

The graph is made up of 15-minute readings stored over the last 8 hours (every 15 minutes the sensor automatically stores glucose reading)

The Reader and app reports allow your patients to interpret their glucose data and help make more informed diabetes management decisions.


Uploading the data to LibreView our secure cloud-based system, enables patients to share their glucose data
with you and their care team, so you can access more in-depth reports to support you to make
treatment decisions.
