Characterization of the third generation enzyme immunoassay IEA-HIV1/2-III for the detection of anti-HIV specific antibodies in human sera.
The sensitivity and specificity of the developed anti-HIV1/2 third generation enzyme immunoassay, the IEA-HIV1/2-III, was examined. The test system for the detection of anti-HIV antibodies included peroxidase-conjugated HIV-specific recombinant Gag protein fragments (epitopes of p24 and p17 proteins), Env-1 (epitopes of p41 and p120 proteins), and Env-2 (p36 epitopes). Sensitivity was evaluated with 346 sera from HIV1-seropositive subjects, Anti-HIV1 Low Titer panels no. 10 and PRB-106 and seropositive panel PRB-931 in comparison with other third- and second-generation assays. The IEA-HIV1/2-III assays are characterized with high sensitivity comparable to the other third generation assays and the better sensitivity with respect to the second generation test-kit to determine HIV-specific antibodies in human sera. The specificity was determined using three hundred sixty-seven potentially cross-reactive samples (but negative for anti-HIV1/2). Only one specimen among them was reactive by IEA-HIV1/2-III.
