How can I help?

The FreeStyle Libre system offers a Trend Arrow with each glucose reading which tells users which way and how quickly glucose levels are changing. So, at any given time, users not only know what their glucose level is currently, but also which way it is heading. Depending on the direction of the trend arrow, users can find out if their glucose levels are changing gradually, moderately, or rapidly, facilitating decision-making.
