Patients with plasma glucose at or above 140 mg/dL (7.8 mmol/L), but not over 200 mg/dL (11.1 mmol/L), two hours after a 75 g oral glucose load are considered to have impaired glucose tolerance.
Za bolnike z vrednostjo glukoze na tešče med 100 in 125 mg/dL (5,6–6,9 mmol/L) se šteje, da imajo moteno glikemijo na tešče.
