AB An enzyme immunoassay using the purified native gp160 for the detection
of human immunodeficiency virus type 1 (HIV-1) antibody was developed.
This assay was determined to be highly specific, since (i) 157 serum
samples that were confirmed negative by Western blot (immunoblot) (WB)
were negative, (ii) 41 serum samples from populations with medical
conditions that might cause nonspecific assay reactivity were all
negative, and (iii) all 15 serum samples that showed false-positive
reactions in one or more commercial HIV-1 screening tests were negative.
The assay gave 100% specificity with a randomly selected and unlinked
panel of 1,000 serum samples from healthy blood donors. The sensitivity
of the assay was assessed by testing 238 samples confirmed as HIV-1
antibody positive by a standardized WB assay. All 238 serum samples
(100%) were reactive in the native gp160 assay. In a dilution panel of
14 weakly WB-positive serum samples, 7 samples reacted two-to fivefold
more strongly in the gp160 assay than in a virus lysate-based assay; the
remaining 7 samples gave comparable reactivities in the two tests. The
reactivities of 13 of these 14 serum samples in the gp160 assay were
higher than in a commercial enzyme immunoassay that uses a recombinant
envelope protein as the antigen. The native gp160 assay was more
sensitive to identify seroconversion. In a well-characterized panel of
sequential blood samples from a seroconverter, the new assay detected
antibodies at least one sample ahead of the other commercial assays
tested.
