Q

Rubella screening

A

checks for Rubella antibodies (iGg)

If the woman has the antibodies, she is Rubella immune and some antibodies will be passed onto fetus.

If Rubella non-immune, recommend vaccine for mother after birth
If a woman gets Rubella during pregnancy, there is an increased risk of birth defects (congenital rubella syndrome), stillbirth, miscarriage and preterm birth.
