The American Red Cross of Northern Ohio is helping to bridge access to health care for blood donors by providing free A1C testing, commonly used to screen for diabetes and prediabetes, on all successful blood, platelet and plasma donations in March.
One-third of people lack access to regular primary care in the U.S., where diabetes affects 1 in 10 people and nearly a quarter of those living with it have been undiagnosed, according to the Centers for Disease Control and Prevention (CDC). The free A1C screening aims to help address this gap by empowering blood donors with valuable information to maintain their health and well-being.
What is the hemoglobin A1C test? This is a common laboratory blood test that doctors use to help diagnose diabetes or prediabetes. Unlike a blood glucose test (or blood sugar test) which provides an instant snapshot of your current blood sugar levels, A1C reflects the average blood sugar levels of an individual over the past 3 months. This gives doctors a better idea of where your blood sugar typically lies, outside of the daily fluctuations.
Why is this important for me? It is estimated that there are over 8.7 million people in the U.S. living with undiagnosed prediabetes or diabetes. Type 2 diabetes accounts for over 90% of all cases and often remains symptomless until damage has been done. Untreated diabetes can lead to plaque build-up in the blood vessels which in turn puts you at greater risk for a stroke or heart attack. The eyes, kidneys, nerves, and skin are particularly vulnerable to the effects of decreased blood flow due to high glucose levels in the blood. Fortunately, prediabetes is reversible with lifestyle changes, so early detection is key.
How should I prepare for my donation? No fasting is required for the A1C test or any other special preparation. Just be sure you are feeling well on the day of donation by getting enough rest, staying hydrated, and eating a well-balanced meal.
When will I get my results? You can expect your results within one to two weeks of your donation. Results will be posted on the Red Cross Donor App or through your donor’s account at RedCrossBlood.org.
What do my results mean? An A1C test result of 5.7% or above will require follow-up with your primary care physician. Your doctor will be able to diagnose and guide you through an appropriate treatment plan.
