TABLE 2.2/2.5

Criteria for the screening and diagnosis of prediabetes and diabetes

A1C5.7–6.4% (39–47 mmol/mol)*≥6.5% (48 mmol/mol)†
Fasting plasma glucose100–125 mg/dL (5.6–6.9 mmol/L)*≥126 mg/dL (7.0 mmol/L)†
Oral glucose tolerance test140–199 mg/dL (7.8–11.0 mmol/L)*≥200 mg/dL (11.1 mmol/L)†
Random plasma glucose≥200 mg/dL (11.1 mmol/L)‡
  • Adapted from Tables 2.2 and 2.5 in the complete Standards of Care. *For all three tests, risk is continuous, extending below the lower limit of the range and becoming disproportionately greater at the higher end of the range. †In the absence of unequivocal hyperglycemia, diagnosis requires two abnormal test results from the same sample or in two separate samples. ‡Only diagnostic in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis.
