Test Description: Rubella Virus IgG Antibody

The Rubella Virus IgG Antibody test measures the presence of IgG antibodies in the blood, which indicate a past infection with the rubella virus or successful vaccination against rubella. IgG antibodies typically appear after the body has been exposed to the virus and remain for life, providing immunity. This test is commonly used to assess immunity in individuals, especially in pregnant women, to ensure they are protected against rubella, which can cause serious birth defects if contracted during pregnancy. A positive result indicates immunity, while a negative result may suggest the need for vaccination to prevent future infection.
