If I develop Rh isoimmunization, how will it be treated?

Rh Incompatability. If maternal antibodies develop against rh-positive proteins, then these antibodies could affect a current or future fetus during pregnancy. This is called rh isoimmunization. Since rh incompatibility is almost completely preventable with the use of prophylactic immunization (immune globulin injection of rhogam), prevention remains the best treatment.
