RESUMEN
Objective To study the relation between the positive rate of platelet antibody and the frequency of platelet transfusion,the total quantity of platelet transfusion,the gender of patients,the blood group of patients through statistic analysis of the data gathered from patients.Methods A total of 5 745 results of platelet antibodies detection assay throughout the year of 2016 were gathered,and statistical relation between the positive rate of platelet antibody and the gender of patients,the blood group of patients and the frequency of platelet transfusion were analyzed.Results The results of platelet antibodies detection assay show that 108 patients were positive among 5 745 patients,and the positive rate of platelet antibody was 1.87％.There were no relations between the positive rate of platelet antibody and the gender of patients or the blood group of patients,while the positive rate of platelet antibody and the frequency of platelet transfusion were positively correlated.Conclusion Platelet antibody production could impact the therapeutic effect of platelet transfusion.Patients with platelet antibodies should receive matching platelet to ensure the therapeutic effect.
