In some cases, the testing method may contribute to skewed HbA1c results. Alcoholism, the taking of large quantities of aspirin, chronic use of opiate-containing drugs, high levels of blood triglycerides, uremia (high blood levels of nitrogen-containing wastes such as urea — usually caused by kidney failure), high blood levels of vitamin C, and high levels of bilirubin (a product of hemoglobin destruction) in the blood can falsely elevate HbA1c results, depending on a laboratory’s testing method. If your HbA1c test results don’t seem to match your blood glucose monitoring results, talk to your doctor about why this might be the case.
HbA1c and you
The HbA1c test is another tool that you and your health-care team can use to tighten your blood glucose control and reduce your risk for diabetic complications. Work with your team to determine the best, lowest HbA1c goal for you.
