The FreeStyle Libre sensor is applied on to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a thin, flexible and sterile fibre is inserted just under the skin. In a study conducted by Abbott Diabetes Care, 92% of patients surveyed (n=119) agree/strongly agree that applying the sensor is less painful1 than a finger prick†.
To obtain a glucose reading, simply perform a quick, painless 1-second scan1 of the Reader or FreeStyle LibreLink app◊ over the sensor. This scan gives you more information than monitoring with blood glucose test strips, without the need for routine finger pricks†. The FreeStyle Libre system also offers LibreView∏,₼ to generate concise reports to assist with the analysis of glucose data.
Each scan of the Sensor gives a current glucose reading, the last 8-hours of glucose history, and a trend arrowθ showing if glucose is going up, down, or changing slowly. The reader can scan through clothingΩ.Close How it Works
