What Is an A1c Test?
Why Is This Important?
Who Should Be Screened?
- Have a family history of diabetes
- Are 45 or older
- Have high blood pressure or high cholesterol
-
Are African American, Hispanic, or Native American, as these groups are at higher risk for diabetes.
Viewing Your A1c Test Results:
Eating a balanced meal before donating blood helps you stay energized and prevents lightheadedness. While some medical tests require fasting, our A1c test does not—so you can eat as usual before your donation. Stay nourished, hydrated, and ready to make a difference!
STEP 1:
Donate Blood – Schedule your blood donation with us.
STEP 2:
Every blood donor at Gulf Coast Blood will receive a free A1c screening with their donation through July 31, 2026.
STEP 3:
Get Your Results – You can check your results by signing into your Digital Donor account within two weeks of your blood donation.
