Rubella Antibodies Test (IgG & IgM)

The Rubella Antibodies Test is used to detect the presence of antibodies to the rubella virus in the blood. There are two types of antibodies that may be tested for: IgG and IgM.

IgG antibodies are produced by the immune system in response to a previous infection or vaccination against rubella. A positive IgG result indicates that the person has immunity to the virus, either from a past infection or vaccination.

IgM antibodies are produced by the immune system in response to a recent infection with rubella. A positive IgM result may indicate a current or recent infection with the virus.

The Rubella Antibodies Test is typically ordered as part of a routine prenatal screening to determine a woman's immunity to rubella. It can also be used to confirm a recent rubella infection in people with symptoms of the disease.
