Test Details
Clinical Significance

Hemoglobin A1c measurements are used as an aid in the diagnosis of diabetes mellitus, as an aid to identify patients who may be at risk for developing diabetes mellitus, and for the monitoring of long-term blood glucose control in individuals with diabetes mellitus. HbA1c is the fraction of hemoglobin A that is first reversibly, then irreversibly glycated at one or both N-terminal valines of the β-chain.1 The longer red blood cells are in circulation and the higher the ambient glucose levels, the higher the concentration of HbA1c. HbA1c reflects the average blood glucose level during the preceding 2 to 3 months.
