What CGM is most accurate?
Researchers found the Senseonics Eversense implantable CGM to be more accurate than the Dexcom G5 and the Abbott Freestyle Libre Pro, the professional version of the CGM, devices.
Are CGM devices accurate?
The limited accuracy of CGM systems is, in part, caused by the compartment in which CGM systems measure glucose. Both a delay related to the measurement technique and the existence of a lag time between changes in blood glucose and interstitial fluid glucose are challenging CGM accuracy.
Is CGM more accurate than fingerstick?
The gold standard for accuracy is a blood draw measurement and both finger sticks and CGMs have error margins (MARD) to that standard. Finger sticks tend to be in the range of 5-10% MARD, while the Libre has a MARD of about 9.2% over 14 days.
Which blood glucose monitoring is best?

Why is my dexcom reading higher?
Pressure on sensor. If the readings are always higher (or always lower) than your meter values and always outside the 20 rule, consider calibrating. Also consider calibrating if your Dexcom G6 and meter numbers don’t match and your expectations or symptoms fit the meter value, not the G6 reading.
How does squeezing finger affect blood sugar?
Anywhere from 5 to 13 percent of study participants had a significantly different blood sugar result (versus no squeezing), depending on how much pressure they put on the finger. On average, blood sugar readings were lower when people put pressure on the finger.
