Stability of Sensor Calibration
FreeStyle Navigator system typically requires a calibration at 10, 12, 24 and 72 hours after insertion of
the sensor. This section presents information about the performance of the system by the 4 calibration
periods. The table (Table 6d) breaks each calibration period into smaller slots and summarizes the
difference from YSI in each slot. The data below demonstrates that there is little change in the system
performance within each period.

* The absolute difference from the YSI reading is measured in mg/dL if the YSI reading is at or below
75 mg/dL.
Sample Glucose Traces
The following figures show examples of glucose traces from the In-Clinic study. These traces are
representative examples of excellent, average and poor performance of the system. These traces show
an overlay of the continuous glucose readings from the FreeStyle Navigator system and the blood
glucose measurements made using the laboratory YSI reference. The blood glucose measurements that
were used to calibrate the system are marked with ‘x’ in the traces. Glucose results from the FreeStyle
Navigator system are shown using circles and the glucose results from the laboratory reference (YSI)
are shown using triangles. Time (hours since sensor insertion) is on the horizontal axis, and glucose
value in mg/dL is on the vertical axis.
