BACKGROUND: Human immunodeficiency virus (HIV) RNA testing of pooled HIV antibody-negative specimens can identify acute HIV infection (AHI) and trigger interventions to reduce transmission during this highly infectious period. METHODS: A Baltimore, MD program serving sexually transmitted disease clinics and other high-risk sites combined HIV testing by third-generation enzyme immunoassay (EIA) with RNA testing of pooled antibody-negative specimens. Laboratory and Disease Intervention Specialists' records were reviewed for program evaluation. A cost analysis was performed. RESULTS: In 22 months, we tested 60,695 specimens for HIV. Of these, 1766 (2.9%) tested positive by EIA. Pooled HIV RNA testing of 58,925 EIA-negative specimens detected 7 cases of AHI (0.01%). Reflex HIV RNA testing of EIA-reactive, Western blot-indeterminate specimens confirmed 4 additional AHI cases (total AHI, 0.02%). Contact tracing detected no additional previously unknown cases of HIV infection. CONCLUSIONS: The utility of pooled HIV RNA testing may be limited by advances in HIV testing technology that reduce the seronegative window period and by characteristics of the local HIV epidemic.
