Detection of Irregular Antibodies after Blood Transfusion for Children with Thalassemia in Hainan / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the irregular antibody positive rate and antibody specificity in children with thalassemia received long-term blood transfusion in Hainan area and analyze the causes of antibody screening positive.@*METHODS@#Micro-column gel method was used to screen the irregular antibody in 49 children who received transfusion treatment in our hospital, and the antibody specificity of the positive samples was evaluated.@*RESULTS@#Fourteen of 49 cases showed positive for screening. Among them, 11 cases showed Rh blood group antibody after detecting antibody specificity, 1 case showed the coexistence of irregular antibody and autoantibody. One case for anti-JK@*CONCLUSION@#Most of the antibodies produced after long-term blood transfusion in the children with thalassemia belong to Rh blood group antibodies; the children with mixed thalassemia are more likely to produce antibodies; the antibody screening positive rate of Li nationality is higher than that of Han nationality, which may be caused by the genetic difference of blood type between Li nationality and Han nationality.
