Feasibility of Rh blood group determination from fetal samples at the time of second trimester abortion by dilatation and evacuation method was investigated. Fetal cord blood was found to be obtained easily, especially when gestational age was more than fifteen weeks. Fetal blood typing was performed easily and accurately. Selective prophylactic immunization of Rh negative patients undergoing dilatation and evacuation procedures is suggested.
