There are no factors that would interfere with the test or the accuracy of the results.
What To Think About
If a woman who wants to become pregnant has not had rubella, she can receive a shot (vaccination) to help protect her against getting the disease. But she must wait 1 month after she gets the shot before becoming pregnant to fully protect her baby.
A woman should not get a rubella shot while she is pregnant, and she should avoid people who have or may have rubella.
A rubella virus culture is not often done because it is a more difficult test.
Exposure to rubella in the third trimester may not be as serious since the baby (fetus) is fully developed. But these babies can have the infection and be contagious.
If congenital rubella is suspected, both the mother and her baby need blood tests.
