With a quick scan of the sensor, FreeStyle Libre shows you where your glucose levels have been, and where they are heading.
The direction in which glucose is heading
Glucose is rising quickly (more than 2 mg/dL (0.1 mmol/L) per minute)
Glucose is rising (between 1 and 2 mg/dL (0.06 and 0.1 mmol/L) per minute)
Glucose is changing slowly (less than 1 mg/dL (0.06 mmol/L) per minute)
Glucose is falling (between 1 and 2 mg/dL (0.06 and 0.1 mmol/L) per minute)
Glucose is falling quickly (more than 2 mg/dL (0.1 mmol/L) per minute)TIR is a measure of the time your glucose stays within the recommended range; the shaded area on your reader, known as Time in Target. Increasing your TIR will have a direct impact on reducing your HbA1c.4
Every 10% increase in TIR can lower A1c by 0.5–0.8%24
Every 5% increase in range has a positive impact on your glucose control4
Spending more TIR can reduce long-term health complications such as vision loss and kidney disease5
ʘComparing 2 groups from lowest to highest scan rate (3.6 and 39.5 scans/day), patients who scanned more frequently using the FreeStyle Libre systems spent 43% more Time in Range.
Abbreviations: A1c: glycated haemoglobin; CGM: continuous glucose monitoring; TIR: time in range.
