Clinical evaluation of the Elecsys® CMV IgM, IgG, IgG Avidity and COBAS AmpliPrep/COBAS TaqMan CMV (COBAS CMV) assays (Roche Diagnostics AG) in the diagnosis and prognosis of congenital CMV infection was performed. In this study, 150 preselected clinical samples (50 primary infection sera, 50 amniotic fluid [AF] and 50 newborn urine) were processed using Roche serological/molecular CMV-specific tests. Results were compared with those obtained by routine assays (comparator assays). The Elecsys® CMV IgM and IgG assays showed a perfect agreement (100%) with the comparator assays. Using the combination of the Elecsys® CMV IgM and IgG Avidity assays results, a primary infection was identified in 100% of cases. Inappropriate avidity CMV IgG values in two samples with very low IgG values ( |
