Immune means being protected from an infection. If you're immune to an infection, it means you can't get the infection. You are probably immune to rubella because you were vaccinated as a child or you had the illness during childhood. A blood test can tell if you're immune to rubella. 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 means a recent infection, a past infection, or that you have been vaccinated against the disease.
A single serologic IgG test can be used to determine if a person has antibodies to VZV from past varicella disease or who may be candidates for varicella-zoster immune globulin (VZIG).
