LIAISON® Immunodiagnostic Test for Rubella Diagnosis in pregnant women


Rubella infection, acquired in the first trimester of pregnancy, is associated with a very high risk of congenital rubella syndrome (CRS). Fetal damage is mostly due to maternal primary infection. Although incidence of CRS is significantly reduced because of successful vaccination programs, especially in developed countries, rubella continues to occur because rubella vaccination coverage is not sufficient throughout the world. As infections are either asymptomatic or accompanied by symptoms which are non-specific for rubella, laboratory techniques are the sole means of diagnosing acute infections.
