Test Description: Rubella Virus IgM Antibody

The Rubella Virus IgM Antibody test detects the presence of IgM antibodies, which are the first antibodies produced by the immune system in response to a recent rubella infection. A positive result indicates a recent or current infection with the rubella virus. This test is particularly important during pregnancy, as rubella infection in early pregnancy can lead to serious birth defects. If a pregnant woman has a positive IgM result, further evaluation and monitoring may be necessary to assess the potential risks to the fetus. A negative IgM result typically suggests no recent infection, but immunity or prior infection may be confirmed by testing for rubella IgG antibodies.
