Measurement of IgG antibodies against human cytomegalovirus
Anti-HCMV IgG titer was determined quantitatively in plasma samples at the Alexander Fleming Institute Clinical Analysis Laboratory by the enzyme-linked fluorescence assay technique using the VIDAS CMV IgG kit (Biomerieux) according to the manufacturer’s instructions. Results were expressed in arbitrary units/mL (AU/mL) as negative (< 4.0 AU/mL) or positive (≥ 4.0 AU/mL) with no ambiguous range.
