目的:分析因罹患白血病而造成患者红细胞ABO血型抗原减弱的原因,确定白血病患者的血型鉴定方法,以降低白血病患者血型鉴定发生错误的机率。方法:对我院收治的一例出现红细胞ABO血型抗原减弱的白血病患者进行ABO血型抗原的血清学正反定型试验、吸收放散试验和唾液血型物质检测。结果:该例白血病患者为A抗原减弱且抗B水平下降,最终ABO血型鉴定为A型。结论:采用血清学正反定型试验、吸收放散试验和唾液血型物质检测的方法可以更为准确对ABO血型抗原减弱的个例进行血型鉴定。
OBJECTIVE: To analyze the reason of the decrease of erythrocyte ABO blood group antigen in patients with leukemia, and to identify the blood type identification of leukemia patients so as to reduce the possibility of wrong identification of blood type in leukemia patients. Methods: One case of leukemia with erythrocyte ABO blood group antigen weakened in our hospital was subjected to serological positive and negative typing test of ABO blood group antigen, absorption and dissipation test and saliva blood type substance detection. Results: In this case, the A antigen was weakened and the anti-B level was decreased. Finally, the ABO blood type was identified as type A. CONCLUSIONS: The positive and negative serotype test, absorption and dissemination test and saliva blood group test can be used to identify the blood group of ABO blood group antigen more accurately.
