According to a Yahoo! Health article (

A rubella blood test detects antibodies that are made by the immune system to help kill the rubella virus. These antibodies remain in the bloodstream for years. The presence of certain antibodies indicates a recent infection, a past infection, or that you have been vaccinated against the disease.

  • The presence of IgM antibodies means you have a current or recent rubella infection.
  • The presence of IgG antibodies means you have immunity against the infection. This immunity could have been received either through vaccination for rubella or a past rubella infection.

As long as the IgM test is negative, both you and your baby are in the clear!
