Performance of parallel screening of Brazilian blood donors with two HIV immunoassays: Implications for sequential immunoassay testing algorithms in other countries

摘要

BackgroundIn Brazil it is mandatory to screen donors for HIV antibodies using two immunoassays (IAs) in parallel. Confirmatory testing is performed only on reactive donors who return for counseling. The goal of this analysis was to determine if concordant IA reactivity accurately predicts infection and can be used for HIV incidence/prevalence analyses.
