Time in Range

What is Time in Range?

Time in Range is the percentage of readings and time per day a person spends within target glucose range.
The FreeStyle Libre system automatically calculates the percentage of time your patient spends in, above, or below target range. 

This Time In Target report shows a person who spent 75% of their day in target glucose range

Why is Time in Range Important?

Every 10% increase in Time In Range can lower HbA1c by 0.8%3

Time In Range increase

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

Spending more Time In Range can reduce long-termhealth complications4

HbA1c has limitations

HbA1c reflects average glucose over the last 2-3 months; it does not show glycaemic excursions of hyper- and hypoglycaemia

An increase in Time In Range results in a decrease in A1c
