HbA1c for Diagnosis of Diabetes Mellitus


Guidance concerning the use of glycated haemoglobin (HbA1c) for the diagnosis of diabetes mellitus Postion Statement

The use of glycated haemoglobin (HbA1c) for diagnosis of diabetes mellitus has been accepted by Medicare for reimbursement. The position statement "Guidance concerning the use of glycated haemoglobin (HbA1c) for the diagnosis of diabetes mellitus" has also been published in the MJA on 20 July 2015.

Like any test, the use of HbA1c for the diagnosis of diabetes mellitus has its strengths and weaknesses. It is important for practitioners to be aware of its potential short comings as well as correctly interpreting a positive and a negative result. The aim of this position paper is to provide a succinct summary of how to optimally use the test to diagnose patients. The test represents an important advance and it is hoped that the guidance provided by this position statement will assist health practitioners to use the test effectively.

ADS Recommendations for the use of HbA1c for the Diagnosis of Diabetes

HbA1c is now acceptable as a diagnostic test for diabetes. The threshold for diagnosis is at an HbA1c level of 6.5%. The existing glucose criteria for the diagnosis of diabetes remain valid as well.

The criteria for the diagnosis of diabetes are now:

In an asymptomatic patient the test should be repeated for confirmation of the result and diagnosis. An abnormal result on 2 different diagnostic tests is also acceptable.

ADS Position Statement on A New Blood Glucose Management Algorithm for Type 2 Diabetes

This position statement developed by the Australian Diabetes Society outlines the risks, benefits and costs of the available therapies and suggests a treatment algorithm incorporating the older and newer agents. Summary of this ADS Position Statement is as follows:
  • Lowering blood glucose levels in people with type 2 diabetes has clear benefits for preventing microvascular complications and potential benefits for reducing macrovascular complications and death.
  • Treatment needs to be individualised for each person with diabetes. This should start with selecting appropriate glucose and glycated haemoglobin targets, taking into account life expectancy and the patient's wishes. For most people, early use of glucose-lowering therapies is warranted.
  • A range of recently available therapies has added to the options for lowering glucose levels, but this has made the clinical pathway for treating diabetes more complicated.

The Position Statement was also published in the MJA (Med J Aust 2014; 201 (11): 650-653.). You can read the MJA article online.


ADS Guidelines for Routine Glucose Control In Hospital

The 2012 ADS Guidelines for Routine Glucose Control in Hospital have been developed over the last year, and cover a range of areas including general hospital wards, myocardial infarction, stroke, steroid-induced hyperglycaemia, enteral and parenteral feeding, insulin pump therapy, end of life situations, the optimal means for achieving glucose control, routine measures in hospital, and how to follow-up patients with newly discovered hyperglycaemia. The guidelines were informed by systematic reviews and evidence where there was any; otherwise they were based on consensus.

The Writing Party comprised David Chipps, Shirley Cornelius, Barbara Depczynski, Kristine Heels, David O’Neal, Jennifer Wong, Sophia Zoungas, and Wah Cheung.

ADS Peri-Operative Diabetes Management Guidelines

These guidelines have been developed by an ADS working group and are primarily intended to provide assistance for those practitioners whose primary focus is not diabetes or who do not have the support of local diabetes expertise in their management of patients with diabetes undergoing surgical procedures.
