CGM target range, 2019 international consensusIn range (3.9–10.0 mmol/L)
ADA goal before meals, many adults with diabetes: 4.4–7.2Above the goal
ADA goal for the peak after meals: below 10.0Within the goal
Fasting lab test (no food for 8 h)In the diabetes range (7.0 or above)

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.
