Technical information
For example, your Dexcom ONE is working
normally in this situation:
• Dexcom ONE reading: 6.5
• Acceptable range (20%): 5.2 – 7.7 mmol/L
• BG meter value: 5.5
• Your Dexcom ONE may not be working normally
when those two numbers are:
• More than 30% apart (if Dexcom ONE
reading is 3.9 or more)
or
• More than 1.7 mmol/L apart (if the Dexcom
ONE reading is less than 3.9)
In that case, use your BG meter value to make
treatment decisions.
For example, your Dexcom ONE may not be
working normally in this situation:
• Dexcom ONE reading: 6.5
• Acceptable range (30%): 4.6 – 8.4 mmol/L
• BG meter value: 9
Your Dexcom ONE may be working normally but
is not aligned with your BG meter when those
two number are:
• Between 21% and 30% apart (if Dexcom
ONE reading is 3.9 or more)
or
• Between 1.2 mmol/L and 1.7 mmol/L apart
(if Dexcom ONE reading is less than 3.9)
In that case, make treatment decisions on
the number that matches your symptoms
and expectations.
