Clinical Significance:

Hemoglobin A1C measurements are used in the clinical management of diabetes to assess the long-term efficacy of diabetic control. Diabetes causes elevated levels of glucose to circulate in the blood. Maintaining normal levels of blood glucose is part of the routine management of diabetics. Continuous and careful management of blood glucose levels prevents development of serious long term complications resulting from vascular impairment such as retinopathy, nephropathy, and neuropathy. Although a fasting blood glucose measurement gives the clinician information about the patient’s status over the last twelve hours, the stable HbA1C offers a more accurate indication of the patient’s long-term diabetic control over the last two to three months.

Reference Ranges:

< 5.7% Normal

5.7 - 6.4% Increased risk for diabetes

>= 6.5% Diagnostic of diabetes

< 7% Goal of therapy

> 8 % Action suggested
