Treatment decisions
With Dexcom ONE, you can make treatment
decisions without using your blood glucose (BG)
meter (BG meter). However, you should keep using
your BG meter to make treatment decisions until
you know how Dexcom ONE works for you.
Sometimes you must use your BG meter instead of
Dexcom ONE. And other times it is best not to treat,
just watch and wait.
Work with your healthcare professional to put
together a plan for making treatment decisions.
Always use your healthcare professional’s
instructions to treat.
You can keep using your BG meter until you are
familiar with your CGM.
Both your BG meter and your CGM give you a
number. They measure glucose from different
sources (blood and interstitial fluid), so those
numbers may be different. And, if you took a lab
test at the same time, the lab result may give you a
third number. The lab result is considered the most
accurate number.
5.1 When to use your BG
meter instead of your
Dexcom ONE
We do not recommend continuous glucose
monitoring for people who cannot or will not:
• Use their BG meter to test their blood glucose if
their symptoms do not match their Dexcom ONE
readings.
• Keep in touch with their healthcare professional
about diabetes management.
