Blood Safety
The safety of the blood supply is maintained through overlapping layers of protection — donor screening, laboratory testing, quarantine procedures, and FDA oversight. These systems were largely built in response to the HIV and hepatitis C contamination crises of the 1980s and 1990s. These guides examine how blood safety works and where vulnerabilities remain.
Is the Blood Supply Safe? History, Recalls, and Current Risks
How safe is the U.S. blood supply today? Congressional investigations, documented recalls, systemic failures, and the real risk numbers — explained.
- ✓ The U.S. blood supply is safer than at any point in history — but it carries residual risks that patients deserve to understand.
- ✓ Approximately 10,000 hemophiliacs and 12,000 other patients contracted HIV from blood products in the early 1980s.
- ✓ 300,000 people acquired hepatitis C from transfusions before screening began in 1990.
FDA Blood Safety Regulations: Enforcement, Inspections, and Standards
How the FDA regulates blood banks and blood products — inspection standards, required testing, enforcement actions, and the five-layer safety framework.
- ✓ The FDA regulates blood banks through a five-layer safety system: donor screening, blood testing, deferral lists, quarantine, and incident investigation.
- ✓ Every donated blood unit must be tested for HIV, hepatitis B, hepatitis C, HTLV, and syphilis at minimum.
- ✓ FDA inspection standards require blood banks to maintain detailed records, calibrated equipment, and trained staff at all collection sites.
