The FDA approved the first continuous glucose monitoring system that don’t require a fingerprick.

Diabetics must regularly monitor their blood sugar. This is usually done by pricking their fingers to draw blood to test on a blood glucose meter, which can be quite inconvenient.

FreeStyle Libre Flash Glucose Monitoring system works by inserting a small sensor wire below the surface of your skin. To read your glucose levels, you simply wave a mobile device above the sensor, and a readout will appear on the mobile device. After a 12-hour initialisation period, the sensor will work for 10 days before it needs to be replaced. It was approved by the FDA on 28 September 2017.

The approval by the FDA was based on a clinical study on 72 adults (over 18 years) with Type 1 or Type 2 diabetes. Blood glucose measurements obtained from the FreeStyle Libre Glucose Monitoring System was compared to those obtained by established laboratory methods in analysing blood glucose.
