Prevalence of Human Immunodeficiency Virus Type 1 p24 Antigen in U.S. Blood Donors — An Assessment of the Efficacy of Testing in Donor Screening

Abstract
We performed a multicenter study in 1989 to determine whether screening whole-blood donors for human immunodeficiency virus type 1 (HIV-1) p24 antigen would improve transfusion safety by identifying carriers of the virus who are seronegative for HIV-1 antibody.
