About this test

The avidity test, CMV IgG measures how strongly IgG antibodies bind to cytomegalovirus (CMV). Binding strength increases over time after infection, helping to date the infection.

Low avidity indicates a recent primary CMV infection, usually within the past 3 months. In pregnancy, this carries the highest risk of passing CMV to the baby, which can cause hearing loss, small head size, vision problems, and developmental delay.

High avidity suggests a past infection, with a much lower risk to the baby, especially when found in early pregnancy. It is most useful when CMV IgM is positive, as IgM can persist for months.
