A blood test to help manage diabetes.
Molecules of glucose (sugar) in the blood bind to this fraction of hemoglobin, and stay bound to it for months. The higher the amount of blood glucose, the higher the amount of hemoglobin A1c, and according to its value, one can obtain the average blood sugar during the previous 8 to 12 weeks. The test indicates how well your diabetes has been controlled in the 2 to 3 months before the test. Information gained from this test can help determine whether your diabetes medication needs to be adjusted. It can also help your health professional estimate your risk of developing complications from diabetes, such as kidney failure, vision problems, and leg or foot numbness. The A1c level is directly related to complications from diabetes: the lower your A1c level, the lower your risk for complications.
Preparation: No special prepartion is needed. Fasting is not required for this blood test. In general, being well hydrated (drinking plenty of water before the blood draw) will help make your veins somewhat easier to locate and access for the blood draw.
