What is total glycohemoglobin?

Total glycohemoglobin, commonly referred to as HbA1c, is a form of hemoglobin that is chemically linked to glucose. It reflects the average blood glucose levels over the past two to three months, providing important information for the management of Diabetes. Clinicians use HbA1c levels to assess long-term blood sugar control and to make decisions regarding treatment adjustments. Elevated HbA1c levels indicate poor glycemic control, which can increase the risk of diabetes-related complications.
