Classification of glucose tolerance abnormalities in CF

	Fasting Plasma Glucose mg/dl (mmol/l)	2-Hour OGTT Glucose mg/dl (mmol/l)
Normal glucose tolerance (NGT)	<100 (5.6)	<140 (7.8)
Abnormal glucose tolerance (AGT)
Indeterminate glycemia (INDET)*	<100 (5.6)	<140 (7.8)
Impaired glucose tolerance (IGT)	<100 (5.6)	140–199 (7.8–11.1)
CFRD FH−	<126 (7.0)	≥200 (11.1)
CFRD FH+	≥126 (7.0)	≥200 (11.1)
Impaired fasting glucose (IFG)	100–125 (5.6–6.9)	NA
