  • Glycated haemoglobin (HbA1c) assessment for the diagnosis of diabetes mellitus overcomes many practical problems associated with traditional blood glucose measurements.
  • However, the test is not without limitations of which the medical practitioner needs to be aware.
  • The possibility of an individual having a medical condition that interferes with the test should always be considered, even though these conditions are rare in most Australian communities.
  • Appropriately used, HbA1c assessment should provide a cost-effective, efficient and simple tool for the early diagnosis of type 2 diabetes.
