Distribution of RH. antigens (D, C, c, E, e)‎ among blood donors in Duhok province-Kurdistan region

Abstract EN

Information of blood antigens and phenotype dissemination is vital for blood donation centers and transfusion administration strategies.

The current study aims to evaluate the frequency of Rh.

Antigens (D,C,c,E,e) Among Blood Donors in Duhok Province.

Materials and Methods: The study was conducted on 500 blood donors recruited to the blood bank at Duhok province between January to April 2015.

Blood samples have been collected from each donor.

ABO and Rh phenotype reactivity was dictated by utilizing tube system as indicated by the producer's direction.

The Rh antigens investigated were D, C, c, E and e.

Result: The predominant blood group was O(38.6%), then A(37.2%), B(18.6%) and the lowest blood group was AB(5.6%).

450 (90%) 0f the blood donors were Rh(D) +ve and the other 50 (10%) were Rh (D) –ve.

Rh antigen phenotype (E,e,C,c,D) was found to be as 474 (94.8%) of the blood donors have had e antigen, 143 (28.6%) have E antigen, 360 (72%) have c antigen and 389 (77.8%) have C antigen.

Conclusion: The study demonstrates that the most continuous Rh antigen in Duhok province is e antigen.

Ten Rh-antigen complexes phenotypes of different frequencies were recorded.
