BackgroundThere is no convincing evidence for the benefit of using anti-D immune globulin (RhIG) in the first trimester [1]. The World Health Organization (WHO) recommends that the determination of Rh status and the offer of RhIG prophylaxis are not considered prerequisites for early first trimester (≤ 63 days) medical abortion [2]. According to the North America Abortion Federation (NAF), it is reasonable to forgo Rh testing and RhIG for women having any type of abortion before 8 weeks from the last menstrual period [3].
