The following Table summarises the 2006 WHO recommendations for the diagnostic criteria for diabetes and intermediate hyperglycaemia.
Diabetes
Fasting plasma glucose >/= 7.0 mmol/L
OR 2 hr plasma glucose >/= 11.1 mmol/L
Impaired Glucose Tolerance
Fasting plasma glucose * <7.0 mmol/L
and
2 hr plasma glucose * >/= 7.8 mmol/L and <11.1 mmol/L
Impaired Fasting Glucose
Fasting plasma glucose 6.1 to 6.9 mmol/L
and (if measured)
2 hr plasma glucose * <7.8 mmol/L
* Venous plasma glucose 2 hrs after ingestion of 75g oral glucose load
DIAGNOSIS of Gestational Diabetes and Diabetes mellitus in pregnancy
* Venous plasma glucose 2 hrs after ingestion of 75g oral glucose load
