Comparison of indirect hemagglutination and 51chromium release tests for detection of Herpes Simplex Virus type 1 and 2 antibodies in patients with recurrent Herpes infections.
Indirect hemagglutination and 51Cr release tests (IHAT and 51-CRT respectively) were compared in patients with recurrent herpes simplex virus (HSV) infections from whom HSV-1 or HSV-2 was isolated. Both tests were equally sensitive and specific in detecting HSV antibodies. However, IHAT was more specific in detecting homologous HSV antibody response in patients with recurrent HSV-2 infections. Past infections with HSV-1 in the patients with dual infections were detected by determining HSV-type specific antibodies by inhibition of IHAT. Cross absorption studies showed that the antibody reactivity measured by the two tests was qualitatively and quantitatively different. Nevertheless, IHAT has been found to be more appropriate test for seroepidemiologic studies of HSV-2 infections because of its specificity, rapidity and less cost, whereas, 51-CRT appears to measure antibodies against recent and more predominant type of infecting HSV.
