Time in range (TIR) is a measure of time your glucose levels you spend in the target glucose range; the shaded area on your reader, known as Time in Target. FreeStyle Libre automatically calculates the percentage of time you spend in, above and below the target range. Increasing your TIR will have a direct impact on reducing your HbA1c.3
Every 10% increase in TIR can lower A1c by ~0.8%20
Every extra hour in range has a positive impact on your glucose control3
Spending more TIR can reduce long-term health complications4
Guidelines recommend spending at least 70% of your Time in Range (70 – 180 mg/dL)14
Below are some helpful ways for you to understand how to read your glucose levels on the FreeStyle Libre reader.
(For example: 70-180 mg/dL as Target Glucose Range)†
