Design outcomes

Primary

MeasureTime frame
The point accuracy of the FreeStyle Libre Flash Glucose Monitoring System, measured using percentage of readings that are within ±20% of the YSI reference value for glucose levels = 80 mg/dL (4.4 mmol/L) and within ±20 mg/dL (1.1 mmol/L) for YSI glucose levels <80 mg/dL(4.4 mmol/L), with and without a potential In-Reader correction. Measured on days 1, 2, 5, 7, 11 and 14 of sensor wear.
