200 mg/dL
= 11.1 mmol/LHigh
A glucose reading of 200 mg/dL is 11.1 mmol/L (11.10 before rounding; 1 mmol/L = 18.01559 mg/dL). It is 20 mg/dL above the top of the target range (180).
200 mg/dL against each published threshold
| Threshold | 200 mg/dL is |
|---|---|
| CGM target range, 2019 international consensus | High (181–250 mg/dL) |
| ADA goal before meals, many adults with diabetes: 80–130 | Above the goal |
| ADA goal for the peak after meals: below 180 | Above the goal |
| Fasting lab test (no food for 8 h) | In the diabetes range (126 or above) |
| 2 hours into a 75 g glucose test | In the diabetes range (200 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.
