The present study has been conducted on 500 pregnant women belonging to Patiala city (Punjab State, India), during various stages of pregnancy, who were investigated for evidence of immunization. Incidence of immunization was found to be 1.20% in total sample and 25.00% in Rh (D) negative pregnant women. All the immunized cases were multiparae. Immunized cases were more in second trimester. Obstetrical histories of immunized cases suggest that five of them were probably immunized due to repeated pregnancies and one case was probably due to previous still births. A greater fertility was observed in the immunized group as compared to other groups. No case of immunization had previous history of blood transfusion. Rh-immunization was also studied in relation to AB0-incompatibility.
