The FreeStyle Libre System

The FreeStyle Libre 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.

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 you shower, swim or exercise.

You can use the FreeStyle Libre reader or FreeStyle LibreLink app to scan your FreeStyle Libre sensor and receive your current glucose reading, up to 8 hours of glucose history and an indication of where your glucose is heading. For a complete glycaemic picture, you must scan your FreeStyle Libre sensor every 8 hours.
