人类红细胞血型属同种异型抗原,目前已发现红细胞血型系统35个,ABO血型基因位点在第9号染色体上,一般不改变,但某些因疾病的原因如白血病或实体瘤等有可能致使ABO血型系统抗原减弱,此种减弱一般是暂时性,随着疾病的缓解逐渐恢复原来的血型。ABO血型的准确鉴定十分重要,血型错误可影响输血工作,ABO血型鉴定错误是引起溶血性输血反应的最主要原因,严重可危及患者生命。在血型鉴定 Human erythrocyte blood group allotype antigens, has been found in 35 red blood cell system, ABO blood group gene locus on chromosome 9, generally do not change, but some due to disease such as leukemia or solid tumors may cause ABO blood group antigen weakening, such weakness is generally temporary, with the disease gradually ease the original blood type. Accurate identification of ABO blood group is very important, blood group errors can affect blood transfusion, ABO blood group identification error is the most important cause of hemolytic transfusion reactions, can seriously endanger the lives of patients.
