Calibration Overview - Dexcom G4 Platinum User Manual

CHAPTER 7: CALIBRATING YOUR DEXCOM G4
PLATINUM (PEDIATRIC) SYSTEM
You must calibrate Dexcom G4 PLATINUM (Pediatric) System sensor
glucose readings to your blood glucose meter.
CONTRAINDICATION
Taking medications with acetaminophen (such as
Tylenol) while wearing the sensor may falsely raise
your sensor glucose readings. The level of inaccuracy
depends on the amount of acetaminophen active in your
body and may be different for each person.

7.1 CALIBRATION OVERVIEW

Your receiver needs calibrations to display continuous sensor glucose
readings and trend information. There are important times when you
must calibrate:
1. 2-hour startup: 2 hours after you insert your sensor
2. 12-hour update: every 12 hours after the 2-hour startup calibration
3. More information needed or other reasons
When calibrating, you must enter your blood glucose values into the
receiver by hand. You can use any commercially available blood glucose
meter. You must calibrate with accurate blood glucose meter values to
get accurate sensor glucose readings.
On the first day of your sensor session, you must enter 2 blood glucose
values into your receiver. You must enter 1 blood glucose value
calibration 12 hours after your startup calibration. You must enter 1
blood glucose value every 12 hours. The receiver will remind you when
it needs these calibrations. You may be prompted to enter additional
blood glucose values as needed.
