values may differ from sensor glucose readings. Using the
sensor glucose readings for treatment decisions could lead
to low or high blood glucose value.
• Do not ignore symptoms of high and low glucose. If your
sensor glucose 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,
so you do not miss a low or high blood glucose value.
• Calibrate at least once every 12 hours. Calibrating less
often than every 12 hours might cause sensor glucose
readings to be inaccurate, and you might miss a low or high
blood glucose value.
• Do not ignore sensor fractures. Sensors may fracture
on rare occasions. If a sensor breaks and no portion of
it is visible above the skin, do not attempt to remove it.
