CHAPTER 3: RISKS AND BENEFITS
3.1 RISKS
There are some known risks with using real-time CGM.
You will not get sensor glucose alerts when the alert function
is turned off, your transmitter and receiver are out of range,
or when your receiver is not showing sensor glucose
readings. You might not notice alerts if you are unable to
hear them or feel the vibration. Sometimes your sensor
glucose reading may be slightly different than your blood
glucose meter. For example, your blood glucose meter may
show a blood glucose value of 78 mg/dL, but your sensor
glucose reading may show as 82 mg/dL. If your low alert is
set at 80 mg/dL, your system will not alert for a low glucose
at this time because 82 mg/dL is still above your low alert
setting. In most cases, the sensor glucose readings will
move in the right direction and will alert you of a high or low
shortly after. If you do not get an alert for any reason, and
you do not take frequent blood glucose measurements with
your blood glucose meter, you might not be aware of low or
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.

solely on CGM alerts to detect low glucose.
