LIAISON® Diasorin Immunodiagnostic Test for the diagnosis of Cytomegalovirus


Human Cytomegalovirus (CMV) is the most common cause of viral intrauterine infection. Fetal damage is mostly due to maternal primary infection. Intrauterine transmission of CMV is significantly reduced in immunoprotected mothers compared to primary infections contracted during pregnancy (< 2% vs 40-50%, respectively). As infections are either asymptomatic or accompanied by symptoms which are non-specific for CMV, laboratory techniques are the sole means of diagnosing acute infections. Early diagnosis of primary infection requires a highly sensitive and quantitative assay for IgG and IgM antibodies, to discriminate between chronic and recent infections.
