HIV status for the retrospectively analyzed negative samples was based on negative results for both HIV antigen assay tests and follow-up tests. These include samples from 10 blood donors.
↵b Acute-phase HIV infection status was based on indeterminate or negative RIBA results, a positive HIV antigen assay result, and documented HIV seroconversion in follow-up samples.
