Calibrating during a significant rise/fall of your BG may affect accuracy of
sensor glucose readings, resulting in you missing a severe low or high
glucose event.
Fingerstick Only
Only use fingerstick measurements from your BG meter for calibration.
Alternative site BG values from your arms, palm of your hand, etc., may be
different and less accurate than your fingerstick BG values. Using alternative
sites for calibration might affect sensor performance, resulting in you missing
a severe low or high glucose event.
Prior to Startup Calibration: Data/Alarm/Alert
After starting a new sensor session, until completing your startup calibrations
you won’t receive any sensor information such as readings, Alarm or Alerts.
Without these, you may miss a severe low or high glucose event.
Continue to take fingerstick measurements during a new sensor warmup
period.
Now that we have reviewed common CGM Safety Statements, let’s focus on
the G5x components.
