Hemoglobin A1C (HbA1C)
Hemoglobin A1C (HbA1C) evaluates long-term blood sugar control. Serum glucose reacts with important proteins in the body rendering them nonfunctional in a process called glycation. Hemoglobin A1C is a reflection of this detrimental reaction. Doctors often follow this blood test in diabetics to monitor disease progression and the effects of treatment. Fasting is not required for this test. Take all medications as prescribed.
