The significant presence of NANB hepatitis was realized after tests were made available to detect hepatitis A (1973) and B (1963).[2,4] Transfusion-associated hepatitis testing negative for hepatitis A and B was classified as NANB. Over 90% of what was once classified as NANB is believed to have been hepatitis C.[2,5]

The first-generation HCV assay was estimated to prevent about 40,000 HCV infections in the United States in the first year (or 111 infections daily).[5] Evidence-based donor screening interventions effectively reduced transfusion-related HCV from over 30% in 1970 to "nearly zero" in 1997.[4] Mathematical models estimate that less than 1 per 2 million transfused units of blood are tainted with hepatitis C.[2,4]
