Diagnostic criteria for diabetes; the American Diabetes Association (Ref. ¹).

1. HbA1c ≥48 mmol/mol (≥6.5%). The test should be performed in a laboratory using a method that is NGSP certified and standardised to the DCCT assay.*

OR

2. FPG ≥7.0 mmol/L (≥126 mg/dL). Fasting is defined as no caloric intake for at least 8 h.*

OR

3. 2-h plasma glucose ≥11,1 mmol/L (≥200 mg/dL) during an OGTT. The test should be performed as described by the World Health Organization, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water.*

OR

4. In a patient with classic symptoms of hyperglycaemia or hyperglycaemic crisis, a random plasma glucose ≥11.1 mmol/L (≥200 mg/dL).

NGSP = National Glycohemoglobin Standardization Program; DCCT = Diabetes Control and Complications Trial; FPG = fasting plasma glucose; OGTT = oral glucose tolerance test.

^*In the absence of unequivocal hyperglycaemia, criteria 1–3 should be confirmed by repeat testing.
