A passive hemagglutination test (PHA) for detecting human immunodeficiency virus type 1 antibodies in serum samples by using envelope glycoprotein (gp160)-coupled sheep erythrocytes was described earlier (M.B. Vasudevachari, K. U. Uffelman, T.C. Mast, R.L. Dewar, V. Natarajan, H.C. Lane, and N.P. Salzman, J. Clin. Microbiol. 27:179-181, 1989). In the study reported here, the applicability of the PHA test to the detection of antibodies in whole-blood and saliva samples has been investigated. We observed a 100% correlation between PHA and commercial enzyme-linked immunosorbent assay in 101 whole-blood samples and 98% correlation between PHA and reactivity to envelope proteins in Western blots (immunoblots) of 53 saliva samples. Furthermore, salivary antibodies could be detected in 19 of the 22 seropositive individuals. As in serum, antibodies to envelope proteins were widely prevalent in all the Western blot-reactive saliva samples.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
