Blood Glucose

Measures glucose levels in blood

  • Requires finger pricks

  • Requires manual testing multiple times a day

  • Requires you to carry strips, lancet and meter to test

  • Provides glucose levels at a single moment of time

FreeStyle Libre 2 sensor icon

FreeStyle Libre Portfolio

Measures glucose levels in interstitial fluid

  • Painless,2 without finger pricks

  • Automatically measures glucose levels

  • FreeStyle Libre 2 sensor delivers readings directly to your smartphone◊,ǁ

  • Provides the whole picture about both the current glucose level and changes over timeφ

  • Helps to see the impact of activites and food

  • Proven to reduce time in hypoglycaemia2,3 and improve overall glucose control4

How does Sensor-based Glucose Monitoring work?

Sensor-based Glucose Monitoring is a technology that allows people with diabetes to easily know their glucose levels and where they're heading without finger pricks.

1. Wear the sensor

The sensors are small, unobtrusive, and easily applied to the back of the upper arm1. The sensors come with an applicator and use a small, flexible tip that is inserted just under the skin.

2. Sensor measures glucose levels

The sensor measures glucose readings through the whole 14 day wear period.

3. View glucose readings on your smartphone

Start your sensor using the FreeStyle LibreLink app to monitor your glucose levels on your smartphone.

If you're using a FreeStyle Libre 2 sensor, you can also receive optional alarms to let you know the minute your glucose is too high or too low.¤

What's the difference between interstitial fluid vs blood glucose?

Sensor glucose readings come from the interstitial fluid, a thin layer of fluid that surrounds the cells of the tissue below the skin and not from the blood.5 Watch the video to find out the difference between interstitial fluid monitoring and blood glucose monitoring.
