What is
Time In Range?

Time in Range (Time in Target) is the percentage of the time that the person spends with their glucose levels in the target glucose range.FreeStyle Libre automatically calculates the percentage of time you spend in, above and below the target range.


Every 10% increase in Time In Range can lower A1c1 by 0.8%12

Every extra hour in range has a positive impact on your glucose control2

Spending more Time In Range can reduce long-term health complications3

Guidelines recommend spending at least 70% of your Time In Range(70–180 mg/dL)4
