Flash Glucose Monitoring Made Easy

Designed to replace the need for routine finger pricks, the
FreeStyle Libre flash glucose monitoring system is made up of:

  • A sensor worn on the back of the upper arm that continuously measures the glucose concentration in the body’s interstitial fluid
  • The FreeStyle Libre Reader to scan the sensor and monitor glucose levels


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. Patients can scan their sensor anytime, anywhere, even through clothing.

For use with the FreeStyle Libre Reader

Patients can use the FreeStyle Libre Reader to scan their sensor to read their glucose levels.

Features & Benefits

Easy to use2

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

Excellent accuracy

Excellent accuracy overall — even in the low glucose range when it matters most.3

Discreet & convenient

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

No finger pricks

Dose insulin, confirm hypo or impending hypo, and be alerted when glucose is rapidly changing — all without the need for finger pricks.

How It Works

Step 1: Apply

The FreeStyle Libre sensor is applied on the back of the upper arm using the applicator. Most FreeStyle Libre system users have reported that applying the sensor was painless.1

Step 2: Scan

With the FreeStyle Libre Reader patients can scan their sensor to see their glucose readings.

Step 3: Read

Patients will be able to see their current glucose reading, 8-hours of data and a trend arrow that shows where their glucose levels are heading.
