WARNINGS
• In a pediatric clinical study, larger differences were
observed between this CGM device and actual
blood glucose values compared to those differences
observed in the adult clinical study. Use your blood
glucose meter for treatment decision.
• I n a pediatric clinical study, a significant number of low
glucose events were not detected by CGM. Do not rely
solely on CGM alerts to detect low glucose.
• Do calibrate at least once every 12 hours. Calibrating
less often than every 12 hours might cause sensor
glucose readings to be inaccurate and glucose
alerts to become unreliable. This could result in you
missing severe hypoglycemia (low blood glucose) or
hyperglycemia (high blood glucose) events.
PRECAUTION
To calibrate the system, do enter the exact blood
glucose value that your blood glucose meter displays
within 5 minutes of a carefully performed blood glucose
measurement. Do not enter sensor glucose readings
for calibration. Entering incorrect blood glucose values,
blood glucose values obtained more than 5 minutes
before entry, or sensor glucose readings might affect
sensor accuracy and could result in you missing severe
hypoglycemia (low blood glucose) or hyperglycemia (high
blood glucose) events.
