Table 1 Criteria for the diagnosis of diabetes in accordance with the American Diabetes Association (ADA) [6]

HbA1c >6.5 %. (The test should be performed in a laboratory using a method that is NGSP certified and standardized to the DCCT assay.)^a OR FPG >126 mg/dL (7.0 mmol/L). (Fasting is defined as no caloric intake for at least 8 h.)^a OR 2-h PG >200 mg/dL (11.1 mmol/L) during an OGTT. (The test should be performed as described by the WHO, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water.)^a OR In a patient with classic symptoms of hyperglycaemia or hyperglycaemic crisis, a random plasma glucose is >200 mg/dL (11.1 mmol/L).
