Anti-Rh antibodies are typically IgG antibodies. IgG is the main antibody class involved in secondary immune responses and is the only antibody class that can cross the placenta from a mother to her fetus. This is important in the case of the Rh factor, as maternal anti-Rh IgG antibodies can cross the placenta and cause hemolytic disease of the newborn if the fetus has inherited the Rh antigen from the father.
