Two commercial enzyme-linked immunosorbent assays (EIAs) for human immunodeficiency virus (HIV) antigens were evaluated for sensitivity and reproducibility by use of supernatant fluid from cell cultures of peripheral mononuclear cells of 18 patients with acquired immunodeficiency syndrome (AIDS) and 12 asymptomatic HIV antibody-positive patients. Both commercial assays dectected HIV antigen in all cultures by day 21; however, the Abbott® HIV antigen EIA (Abbott Laboratories, North Chicago, IL) detected HIV antigen three to seven days earlier in 15 of 48 cultures (31%), on the same day in 32 cultures (67%), and three days later in 1 culture (2%) when compared with the DuPont® HIV antigen EIA (DuPont Laboratories, Wilmington, DE). In serial twofold dilution experiments, the Abbott HIV Ag EIA was found to have at least a twofold to eightfold increased sensitivity over the DuPont assay. Repeat testing of 15 initially positive supernatant fluids by both assays revealed that 13 of 15 and 12 of 15 were consistently positive by the Abbott and DuPont assays, respectively. The authors conclude that the Abbott EIA demonstrated better performance in this study than the DuPont EIA for detection of HIV in cell culture because of its shorter time-to-positivity and greater sensitivity.
