Abbott’s FreeStyle Libre Flash Glucose Monitoring System eliminates finger pricking for diabetics. The insertion of a tube under the skin is required, therefore the procedure, while continuous and comfortable, is still invasive.

A user wears a sensor on the back of the upper arm, and through a small tube inserted just under the skin, it measures blood sugar levels of tissue fluid. A reader is scanned over the sensor, and results are reported in less than one second. Real-time results, a historical trend and the direction the glucose is heading are displayed, so the user can adjust insulin intake . Disposable and water resistant, the sensor can be worn for up to two weeks
