About this test

The rubella IgG avidity test measures how strongly IgG antibodies bind to the rubella virus. Antibody strength (avidity) increases over time after infection.

Low avidity indicates a recent primary rubella infection, usually within the past 2–3 months. In early pregnancy, especially the first 16 weeks, this carries a high risk of congenital rubella syndrome, which causes deafness, cataracts, and heart defects in the baby.

High avidity suggests past infection, vaccination, or reinfection, with low risk to the baby.

It is especially useful when rubella IgM is positive during pregnancy.
