8.9 mmol/L
= 160 mg/dLIn range
A glucose reading of 8.9 mmol/L is 160 mg/dL (160.3 before rounding; 1 mmol/L = 18.01559 mg/dL). It is 5.0 mmol/L above the bottom of the target range (3.9) and 1.1 below the top (10.0).
8.9 mmol/L against each published threshold
| Threshold | 8.9 mmol/L is |
|---|---|
| CGM target range, 2019 international consensus | In range (3.9–10.0 mmol/L) |
| ADA goal before meals, many adults with diabetes: 4.4–7.2 | Above the goal |
| ADA goal for the peak after meals: below 10.0 | Within the goal |
| Fasting lab test (no food for 8 h) | In the diabetes range (7.0 or above) |
| 2 hours into a 75 g glucose test | In the prediabetes range |
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.
