Cytomegalovirus (CMV) is a virus from the herpesvirus family that can cause a variety of clinical manifestations, from ARVI to internal organ damage. CMV is considered an opportunistic infection, which can be particularly dangerous for debilitated patients.

IgG antibodies to CMV indicate the presence of a current or past infection. They appear 10-14 days after infection and can persist in the body for life. Their presence does not provide sustained immunity, so the presence of antibodies in newborns may be the result of maternal immunity rather than a sign of infection. For a more accurate assessment, it is necessary to compare the levels of IgG in the child and the mother, as well as to monitor the dynamics of changes in the level of antibodies.

To confirm the activity of the infection, a study of “paired” sera is performed - determination of IgG levels at intervals of 2-3 weeks, where an increase in the level indicates an active process.
