What is the FreeStyle Libre flash glucose monitoring system?

The FreeStyle Libre flash glucose monitoring system is the first product in the flash glucose monitoring category and is designed to liberate people with diabetes from many of the hassles of glucose monitoring1, such as routine finger pricking.

The FreeStyle Libre system contains two components:

FreeStyle Libre sensor: A small, disposable 14-day sensor that is worn on the back of the upper arm and continously measures glucose levels and stores them for a period of 8 hours. Every time the user scans the reader over the sensor, the glucose data from sensor is transferred to the reader in 1 second.

FreeStyle Libre reader: A compact, handheld reader that displays glucose readings and stores up to 90 days of glucose data. When the reader is scanned over the sensor, it shows a current glucose reading, last 8-hours of data as well as a trend arrow (indicating if glucose is going up, down or staying steady). To obtain a glucose reading, simply perform a quick, 1-second scan of the reader over the sensor. This easy scan gives you more information than blood glucose monitoring without the need for routine finger pricks2.


Abbott’s IMPACT is a six-month clinical trial involving 252 adult participants living with well-controlled type 1 diabetes across 23 European diabetes centers. IMPACT was published in The Lancet in September 2016. Data on file

2 A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycaemia or impending hypoglycaemia is reported by the system or when symptoms do not match the system readings.
