WHO criteria for interpreting 2-h OGTTa
| 2-h OGTT result, mmol/L (mg/dL) | ||
|---|---|---|
| 0 h | 2 h | |
| Impaired fasting glucoseb | >6.1 (110) to <7.0 (126) | <7.8 (140) |
| Impaired glucose tolerancec | <7.0 (126) | >7.8 (140) to <11.1 (200) |
| Diabetesd | >7.0 (126) | >11.1 (200) |
a
Values are for venous plasma glucose using a 75-g oral glucose load. From the WHO (21).
b
If 2-h glucose is not measured, status is uncertain as diabetes or impaired glucose tolerance cannot be excluded.
c
Both fasting and 2-h values need to meet criteria.
d
Either fasting or 2-h measurement can be used. Any single positive result should be repeated on a separate day.
