Abstract
Unlike ABO antigens, Rh antigens are present only on
Red Blood Cells (RBC), RhO(D) antigen is clinically the
most important in the Rh system because it is highly
antigenic. In India, as reported, 95% population is Rh positive
whereas 05% is Rh Negative(approximately). Rh antibodies
are the major cause3 of haemolytic disease of newborn
(HDN) and lead to destruction of transfused Rh Positive
red cells. A total number of 799 pregnant mothers having
RhD Negative Blood Group (and also their husband
possessing RhD Positive Blood Group) were surveyed. Out
of the 799 babies born, 662 possessed RhD Positive and
137 possessed RhD Negative Blood Group. Besides this,
twin babies born of RhD Negative mother and RhD Positive
Biological Father were computed separately (Total No.of
such mothers being 12). In case of twin delivery, the twins
babies all possessed RhD Positive Blood Group. Calculation
shows that about 17% of babies were RhD Negative and
83% were RhD Positive.
