While the hemoglobin A1c test can be used to diagnose diabetes, doctors do not often rely on the results of just one test to make this diagnosis.

Your doctor may order a repeat of your hemoglobin A1c test or compare your results with other tests that have been performed.

They can address how your hemoglobin A1c results fit into the reference ranges, what follow-up tests might be required, and what next steps to take in managing your health.

If your test results show that you have prediabetes, this means that you could have an increased risk of diabetes in the coming years. Your doctor may advise you to make changes to your diet, exercise routine, and other aspects of your lifestyle that could reduce your chance of developing diabetes or delay the onset of this disease.
