Abstract: Objective To study the effect of low-titre erythrocyte antibodies on tumor patients with blood transfusion in Xinjiang. Methods A retrospective analysis was performed on 667 cases of tumor patients in our hospital. According to the efficacy of blood transfusion, the patients were divided into effective group and ineffective group. The relationship between the transfusion efficacy and low titre antibody under the influence of different factors is analyzed. Results The effective infusion rate in this study is 81.86% and the incidence of adverse reactions is 0.45%. Invalid blood transfusion is closely related to pregnancy frequency, nationality and other factors, and the difference was statistically significant (P<0.05). The detection rate of low potency antibody is closely related to the number of pregnancies, previous blood transfusion history and national factors, and the difference was statistically significant (P<0.05). Compared with anti-human globulin method, the detection rate of low potency antibody is significantly different in various detection methods (P<0.05). Conclusion The inefficacy of transfusions exists in patients in this region, and the low potency antibody is one of the factors affecting the efficacy of blood transfusion. Medical institutions should reasonably set up re-examination rules to strengthen the detection of low-valency antibodies.
