CHAPTER 8: SENSOR GLUCOSE READINGS AND TRENDS

This chapter teaches you how to view your sensor glucose readings and trend information. The trend graph
provides additional information that your blood glucose meter does not. It shows your current glucose value,
the direction it is changing and how fast it is changing. The trend graph can also show you where your
glucose has been over time.
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.
Your blood glucose meter and sensor measure glucose from two different types of body fluids: blood and
interstitial fluid. Therefore, readings from your blood glucose meter and sensor may not match.

WARNING
Do not use the Dexcom G4 PLATINUM System for treatment decisions, such as how
much insulin you should take. The Dexcom G4 PLATINUM System does not replace a
blood glucose meter. Always use the values from your blood glucose meter for
treatment decisions. Blood glucose values may differ from sensor glucose readings.
Using the sensor glucose readings for treatment decisions could lead to low or high
blood glucose value.
