Criteria for the Screening and Diagnosis of Diabetes

FPG100–125 mg/dL (5.6–6.9 mmol/L)*≥126 mg/dL (7.0 mmol/L)
OGTT140–199 mg/dL (7.8–11.0 mmol/L)*≥200 mg/dL (11.1 mmol/L)
RPG≥200 mg/dL (11.1 mmol/L)
  • * 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, results should be confirmed by repeat testing.

  • Only diagnostic in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis. RPG, random plasma glucose.
