How does Dexcom G6 compare to my blood glucose meter in terms of accuracy?
Dexcom CGM systems provide much more information for users than traditional Self-Monitoring of Blood Glucose (SMBG) does. For Dexcom G6 users, the expected level of accuracy is based on comparisons to fingerstick results--which require careful consideration of timing and technique consistency when drawing blooding glucose values.

What do I do if my blood glucose meter is not within the accuracy (20/20) range of my Dexcom G6?
There may be times when your readings temporarily don’t match, but don't panic, as they are likely to become closer over time. You may find that this occurs for a few common reasons.
Is my Dexcom sensor accurate?
The test your doctor does is considered a more accurate glucose number than any products you use at home. Both BGMs and Dexcom G6 are compared to that doctor’s test to measure accuracy in clinical studies.
