Sensor Stability - Dexcom G6 Pro User Manual

Sensor Stability

Sensors can be worn for up to 10 days. Performance was estimated by
calculating the percentage of G6 Pro readings within 15 mg/dL or 15%
(15/15%), 20 mg/dL or 20% (20/20%), and 40 mg/dL or 40% (40/40%),
of the YSI values at the beginning (Day 1, 2), middle (Day 4, 5) and
end (Day 7, 10) of the G6 lifecycle. For blood glucose values less than
or equal to 70 mg/dL, the absolute difference in mg/dL between the
two glucose results was calculated. For values greater than 70 mg/dL,
the absolute difference (%) relative to the YSI values was calculated.
In addition, the mean absolute relative difference (MARD) shows the
average amount the sensor readings differ from the YSI glucose. The
MARD values included in Table 6-A and 6-B show consistent accuracy
and sensor stability over the 10-day life of the sensor.
