ABCD position statement on haemoglobin A1c for the diagnosis of diabetes 

Key Points 

  • An International Expert Committee report has recommended that HbA1c be used as the preferred test for diagnosing diabetes. The American Diabetes Association has since added this test as an option for diagnosis

  • The test has a number of potential advantages compared to glucose in identifying patients as having diabetes

  • Persistent analytical differences between laboratories and inherent limitations in HbA1c in assessing glycaemia mean that a single HbA1c threshold for diabetes could miss subjects with hyperglycaemia while identifying some individuals without

  • ABCD recommends continuing to diagnose most patients with type 2 diabetes using existing glucose criteria, but can see a role in the UK for HbA1c to triage patients into those who do or do not need further glucose testing
