RESUMO

Primary varicella-zoster virus (VZV) infection is a serious illness in immunocompromised individuals, and a rapid, sensitive, and reliable assay to identify high-risk VZV-susceptible patients would be clinically useful. An enzyme-linked immunosorbent assay (ELISA) for antibody to VZV was compared with the fluorescent antibody-to-membrane antigen (FAMA) assay and found to be similar in both sensitivity and specificity. The antibody titers determined by both assays were also similar. The absence of antibody detected by ELISA correlated with susceptibility to VZV infection. Because it is simple to perform and has equivalent sensitivity to FAMA, ELISA should be useful for VZV antibody testing in diagnostic and research laboratories.
