Evaluation of assays for detection of IgG against EBNAa

Assay and resultNo. of samples with the following ACIF result:Sensitivity (%)Specificity (%)Correlation (%)
IF, IgG EBNA-178.191.488.0
CLIA-L, IgG EBNA-190.632.347.2
CLIA-I, IgG p7293.879.683.2
ELISA, IgG EBNA-1b87.589.989.3
  • a For calculating sensitivity and specificity, indeterminate results were considered the most adverse.

  • b For ELISA, data are for 121 results (32 ACIF positive and 89 ACIF negative).
