New nationwide screening data from the American Red Cross shows that 1 in 5 U.S. blood donors have elevated A1C levels, indicating widespread presence of prediabetes and diabetes among adults considered generally healthy. The findings are based on free A1C testing conducted on more than 920,000 donors during 2025. Notably, nearly 80% of individuals with elevated A1C levels fell within the prediabetic range, highlighting a major preventive care opportunity through early detection and lifestyle intervention.
Hidden Metabolic Risk Identified
A1C testing measures average blood glucose levels over several months and is a primary indicator for diagnosing prediabetes and Type 2 diabetes. Many individuals remain undiagnosed due to lack of routine screening. Untreated metabolic disease increases risk of heart disease, stroke, kidney failure, and nerve damage, making early identification critical for long-term health outcomes.
Free Nationwide Screening Initiative
To expand preventive access, the Red Cross announced free A1C screening for all successful blood, platelet, and plasma donations during March 2026. Donors will receive results through secure digital platforms, alongside routine mini-physical metrics such as blood pressure, hemoglobin, pulse, and temperature.

With approximately 2.5 million annual donors, the initiative positions blood donation programs as valuable community-based health screening platforms capable of bridging gaps in preventive care and chronic disease awareness.
