The cgm readings do not match my meter readings. Should I be concerned about this?

Blood glucose (BG) meters take glucose readings from plasma blood whereas sensors take readings from interstitial fluid. Most of the time glucose travels first to your blood and then to your interstitial fluid. Because of how glucose travels, your BG meter readings and sensor glucose readings will rarely match exactly. This is quite normal. When using your technology, you should concentrate on trends and patterns instead of individual values.
