What is a Trend Arrow? How does it work? What does it tell users?

Do not ignore symptoms that may be due to low or high blood glucose. If you have symptoms that do not match the Sensor glucose reading or suspect that your reading may be inaccurate, check the reading by conducting a finger stick test using a blood glucose meter. If you are experiencing symptoms that are not consistent with your glucose readings, consult your health care professional.

What is a Trend Arrow? How does it work? What does it tell users?

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.¹
