Type 2 Pathway - Diagnosis

The current diagnositic criteria for type 2 diabetes are:

Note current advice is that only an HbA1c is required when screening for diabetes.

  • Symptomatic and HbA1c ≥ 50 mmol/mol and,if measured fasting glucose ≥ 7.0 mmol/L or random glucose ≥11.1 mmol/L.
  • Asymptomatic HbA1c ≥ 50 mmol/mol and,if measured fasting glucose ≥ 7.0 mmol/L or random glucose ≥11.1 mmol/L. Repeat HbA1c or fasting glucose.
  • Asymptomatic HbA1c 41 - 49 mmol/mol and,if measuredfasting glucose 6.1 - 6.9 mmol/L (pre-diabetes) Repeat test 6-12 monthly.
  • Two hour post 75g glucose load (glucose tolerance test) plasma glucose >11.1mmol/L.

* When HbA1c and fasting glucose are discordant with regard to diagnosis of diabetes, repeat testing at an interval of 3-6 months is recommended. The test that is above the diagnostic cut point should be repeated - if the second test remains above the diagnostic threshold then diabetes is confirmed. If the second result is discordant with the first then subsequent repeat testing at intervals of 3-6 months is recommended. Patients with discordant results are likely to have test results near the diagnostic threshold.
