HBA1C – why would I need this test?

HbA1c is a blood test that is used to help diagnose and monitor people with diabetes. It is also sometimes called a haemoglobin A1c, glycated haemoglobin or glycosylated haemoglobin.

The test for HbA1c indicates how well your diabetes has been controlled over the last few months. It can also be used to diagnose diabetes.

People with diabetes are advised to have this test every 3 to 6 months, or more frequently if it is not under control. No preparation is needed for this test.
