 AB    Three blood donor sites in the United States evaluated a new MicroTrak
       II enzyme immunoassay pending FDA approval for the detection of
       antibodies to HIV-1 and/or HIV-2. It was compared with licensed
       reference assays. Fresh samples from 10,468 volunteer blood donors, and
       417 archival frozen samples positive for HIV-1 antibodies were tested.
       The MicroTrak II assay had a sensitivity of 99.76% on the HIV-1 positive
       samples. One sample that tested negative was collected in 1988, had been
       subjected to several freeze-thaw cycles and was visually cloudy. This
       sample is undergoing further evaluation. The specificity of the blood
       donor samples was 99.86%. TABULAR DATA, SEE ABSTRACT VOLUME. The
       MicroTrak II anti-HIV 1/2 assay has equivalent sensitivity and
       specificity to currently licensed methods except for one tested sample
       undergoing further evaluation.
