Abstract

The performance of fifteen, commercially available, VZV IgG assays and an "in house" indirect immunofluorescence (IF) assay has been compared to a reference VZV IgG time resolved immunofluorescence assay (VZV TRFIA). A panel of 273 VZV TRFIA IgG positive serum samples and 136 VZV TRFIA IgG susceptible sera, collected from a number of UK hospitals was used. Irrespective of the interpretation of equivocal results the most sensitive assays were Dade Behring EIA (97.4%), "in house" IF (95.2%), Human EIA (92.3%) and Becton Dickinson latex agglutination (94.1%). The least sensitive assays were Virion EIA (69.6%), Diesse EIA (68.9%) and Diasys EIA (68.5%). The least sensitive (
