Abstract. To try and identify those women at possible risk of Rh immunization during pregnancy and so limit ante‐partum treatment to them, 558 smears from 140 women were examined for fetal cells. Those found to have more than an estimated 0.05 ml of fetal blood were then given Rh IgG. Two of 134 untreated women and one of six treated women became immunized. The reason for the latter failure is uncertain. The total frequency of immunization, 2.2%, does not differ from that expected in the absence of treatment.
