CGM target range, 2019 international consensusIn range (70–180 mg/dL)
ADA goal before meals, many adults with diabetes: 80–130Within the goal
ADA goal for the peak after meals: below 180Within the goal

The CGM range and the ADA goals are for people who have diabetes; a care team can set different ones. The two lab tests are how diabetes is diagnosed, on a plasma sample, and ADA asks for two abnormal results unless the high glucose is unmistakable. One meter or CGM reading does not diagnose anything.
