  • Title: Enzyme immunoassay for antibodies to Epstein-Barr virus nuclear antigen.
    Author: Smalley DL, Dunn CE, Hechinger MC.
    Journal: Clin Lab Sci; 1990; 3(6):397-8. PubMed ID: 10150041.
    Abstract:
    An enzyme immunoassay that detects IgM and IgG antibodies to the nuclear antigen of Epstein-Barr virus (EBV) is evaluated. The EIA was compared with a rapid monoscreen (Immunoscan-IM) and an indirect fluorescent antibody procedure to determine the correlation of the new test with the current methodology. Among 73 patients tested for heterophilic antibody, 36 were positive; 25 of these had IgM antibodies to nuclear antigen. The sensitivity of the EIA compared to the mono screen was 69.4% and specificity was 97.3%. In comparison with fluorescence assays for IgG to the nuclear antigen, 94 patients were tested with 84 showing positivity by the fluorescent method. Among these, 80 were positive by EIA yielding a sensitivity and specificity of 95.2% and 90.0%, respectively. The EIA does not appear sensitive enough for replacement of the monoscreen but was a sensitive, cost-effective alternative to the indirect fluorescent antibody test.
