The purpose of Rhogam is to bind to and remove the RhD antigens so that the mother does not form an immune response against the antigen in fetusโ blood. Itโs given to at-risk Rh negative moms at 28 weeks and at delivery.
weenathonThis question confused me because wouldn't she have already formed antibodies in her previous pregnancy?+8
nbmeanssuxPregnant mothers don't form anti-RhD antibodies until around 28 weeks (that's why we administer it then) so she shouldn't have formed any from the 12wk aborted first pregnancy+10
