Abstract

The present study has been conducted on 1500 pregnant women of Patiala. All the cases were examined for ABO and Rh(D) blood groups; the Rh(D)-negative cases also for evidence of Rh-immunization. The distribution of ABO blood groups reveals 40.20% blood group B, 29.27% blood group O, 22.80% blood group A, and 7.73% blood group AB. Rh(D) blood types reveal 94.40% positive cases and 5.60% negative cases. Incidence of immunization was found to be 1.33% in the total sample and 23.80% in Rh(D)-negative cases. Comparison of these frequencies has been sought with some other studies.
