Consensus assays: Abbott CMV-M EIA, Gull CMV IgM ELISA, and Trinity Biotech/Centocor CAPTIA CMV-M. Abbreviations: Pos, positive; Eqv, equivocal; Neg, negative; None, no interpretation. Sensitivity, specificity, and agreement are relative values for the consensus interpretation and resolved values for the resolved interpretation.
