Traditional blood glucose monitoring provides users with glucose readings that represent distinct points in time. Users do not get information about how their glucose levels have been changing or where their glucose levels are heading. This means it can be easy to miss glucose fluctuations. The FreeStyle Libre system, which is based on flash glucose monitoring, is a new way to obtain glucose readings. It allows the user to get their current glucose reading by just scanning the reader over the sensor, and also provides a complete picture of glucose variations.
