Freestyle Libre: Remove sensor - how it works

Freestyle Libre uses a sensor to measure blood sugar levels, which you must periodically remove and replace with a sensor. At first this seems a bit complex, but it is done within a few seconds.

Freestyle Libre measures blood sugar with a sensor

The detection of glucose levels using Freestyle Libre is very convenient. You just have to remember to replace the sensor in time. However, before you can remove the sensor, you must have attached it for the first time.

• With Freestyle Libre, you save yourself the annoying and uncomfortable stings in your fingers to determine the glucose level. You only hold the reader briefly over a small sensor. The sensor is about the size of a two-euro coin and has a sensor that is about five centimeters long.
• The small, thin sensor is attached to the upper arm of the diabetic. Before you start, however, disinfect the area on the upper arm with one of the included alcohol wipes. The thin probe is then inserted into the skin using the sensor applicator. The process is quick and usually barely noticeable. In a separate article, we describe in detail how you can easily fix the Freestyle Libre Sensor. The sensor is waterproof and normally does not hinder you in everyday life.
• You then measure the blood sugar level using a small, light reader. To do this, hold the reader over the sensor for a few seconds. Conveniently, the reader can easily read the current glucose value through clothing.
• You can scan your blood sugar level as often as you like, but at least every eight hours. The data is saved on the reader for three months.

Removing the sensor: it's easy

Approximately every two weeks you have to replace the Freestyle Libre sensor and replace it with a new one.

• Removing the old sensor is even easier than attaching the new sensor.
• To remove the old sensor, grasp the edge of the sensor with your thumb and index finger and then simply pull it out.
• Just like attaching, removing the sensor is usually painless.
• Finally, clean the area with one of the included alcohol wipes.
