13.5 SENSOR INACCURACIES
Inaccuracies are usually related to your sensor only and not your
receiver or transmitter. Your sensor glucose readings are meant to be
used for trending purposes only. Your blood glucose meter and sensor
measureyourglucosefromtwodifferenttypesofbodyuids:bloodand
interstitialuid.Therefore,yourreadingsfromyourbloodglucosemeter
readings and sensor may not match.
WARNING
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.
