American Diabetes Association criteria for defining increased risk (impaired) and diagnosis of diabetes (2).

	Normal	Impaired^b	Diabetes^c
HbA1c (%)	< 5.7	5.7 – 6.4	≥ 6.5
Fasting Glucose (mg/dl)	< 100	100 – 125	≥ 126
2-hour Glucose (mg/dl)^a	< 140	140 – 199	≥ 200
Random Glucose (mg/dl)			≥ 200^b

During a 75 gram oral glucose tolerance test.

Any measure of impaired glycemia is consistent with increased risk for diabetes, or prediabetes, although the risk is continuous throughout the ranges becoming disproportionately greater at the higher ends of each range.

Any one measure of diabetic glycemia requires confirmation by repeat testing, unless two or more different measures indicate diabetic glycemia, in which case the diagnosis of diabetes is confirmed.

Sufficient for a diagnosis of diabetes when accompanied by classic symptoms (polyuria and polydipsia) of hyperglycemia.
