WARNING
Do not ignore symptoms of high and low glucose. If your
sensor glucose alerts and readings do not match your
symptoms, measure your blood glucose with a blood
glucose meter even if your sensor is not reading in the
high or low range. Solely relying on the sensor glucose
alerts and readings for treatment decisions could result in
you missing severe hypoglycemia (low blood glucose) or
hyperglycemia (high blood glucose) events.
