Diagnostic criteria for diabetes11

SymptomaticOne of the three abnormal blood tests
  • HbA1c = 48 mmol/mol or above

  • Fasting plasma glucose = 7.0 mmol/L or above

  • Random plasma glucose = 11.1 mmol/L or above

AsymptomaticTwo of the three abnormal blood tests collected on different days
  • HbA1c = 48 mmol/mol or above

  • Fasting plasma glucose = 7.0 mmol/L or above

  • Random plasma glucose = 11.1 mmol/L or above

High risk of developing T2D0 diagnostic results but abnormal range
  • HbA1c = 42–47 mmol/mol

Not diabetic0 diagnostic blood tests
  • HbA1c <42 mmol/mol

  • HbA1c = glycated haemoglobin; T2D = type 2 diabetes.
