STEP 368: Glycated (Glycosylated) Hemoglobin: HbA1c: New directions to diagnose diabetes (CE: 1.0)


Also known as hemoglobin A1c, HbA1c, A1C orHb1c, Glycated (Glycosylated) Hemoglobin is a form of hemoglobin used primarily to identify the average plasma glucose concentration over a prolonged period of time. Increased levels of glycated hemoglobin have been associated with cardiovascular disease, nephropathy, and retinopathy in diabetes mellitus. Monitoring the level of HbA1c in juvenile-onset (type 1– autoimmune) diabetes may improve treatment. This article discusses new methods of diagnosing diabetes.


Learning Objectives:

  • Define HbA1c
  • Discuss the impact of HbA1c on patients with diabetes
  • Describe the diagnostic criteria for diabetes
