IMMUNOGLOBULIN-G ANTIBODY CAPTURE ENZYME-LINKED-IMMUNOSORBENT-ASSAY - A VERSATILE ASSAY FOR DETECTION OF ANTI-HUMAN-IMMUNODEFICIENCY-VIRUS TYPE-1 AND TYPE-2 ANTIBODIES IN BODY-FLUIDS

In tests on specimens of dried blood, saliva, and urine from 55 human immunodeficiency virus (HIV-seropositive and 55 HIV-seronegative patients, an immunoglobulin G capture enzyme immunoassay for the detection of antibodies to HIV types 1 and 2, GACELISA, gave 109 of 110, 109 of 109, and 109 of 110 correct results, respectively. This performance, achieved in a laboratory previously unfamiliar with the assay, suggests that GACELISA is a useful new epidemiological tool for the study of HIV infection, equally applicable to all three kinds of specimen.
