Antigen profile and antibody frequency of Wra in voluntary blood donors in Shaanxi province, containing 2 clinical cases of anti-Wra identification / 中国输血杂志

ABSTRACT

【Objective】 To understand the antigen profile and antibody frequency of Wra in voluntary blood donors in Shaanxi province. 【Methods】 Wra antigen and antibody screening as well as blood group typing and antibody identification were performed by serological tests and confirmed by genetic testing. 【Results】 The incidence of Wra antigen in 7 490 voluntary blood donors was 0.013%(1/7 490), and the frequency of anti-Wra in 729 voluntary blood donors was 0.823%(6/729). 【Conclusion】 This study explored the polymorphism of Wra antigen and antibodies in blood donors, which is informative in the risk assessment of blood transfusion and the screening and identification of respective antibodies.
