Analysis of Blood Type Unexpected Antibody Screening Results and Disease Types of Clinical Patients from A Hospital in Chengdu,Sichuan Province from 2012 to 2021
Objective To analyze blood type unexpected antibody and disease characteristics of inpatients in a hospital,and provide a reference for optimizing precise transfusion schemes and improving clinical transfusion safety.Methods The data of unexpected antibody screening and identification in the General Hospital of Western Theater Command from January 2012 to December 2021 were collected,while information on these patient age,gender,blood transfusion history,pregnancy history and disease diagnosis were also collected.The positive rate,composition ratio and disease characteristics of unexpected antibodies were analyzed.Results The positive rate of unexpected antibody screening was 0.55%(1 736/315 456),in which females were higher than males(0.69%vs 0.44%,χ2=90.107,P＜0.05),patients with a history of blood transfusion or(and)pregnancy were higher than those without a history of blood transfusion or(and)pregnancy(75.69%vs 22.81%,χ2=971.098,P＜0.05),and patients aged 40～80 accounted for 72.93%(1 266/1 736).Patients diseases with unexpected antibody positive accounted for 80.41%(1 396/1 736),mainly including digestive system diseases,immune diseases of blood and hematopoietic organs,tumors,urogenital system diseases,circulatory system diseases,musculoskeletal system and connective tissue diseases.Moreover,91.88%(1 595/1 736)of the patients with anti-screening positive underwent antibody identification,in which the majority of unexpected antibodies were Rh blood group system[41.57%(663/1 595)],Lewis blood group system[11.22%(179/1 595)],and MNS blood group system[6.90%(110/1 595)].Antibody specificity was mainly characterized by anti-E[32.41%(517/1 595)],anti-Lea[10.47%(167/1 595)],and anti-M 6.08%(97/1 595).Other antibodies[35.8%(571/1 595)]were mainly no-detected specific antibodies.Conclusion The screening results of blood type unexpected antibodies and disease type analysis are of great significance for transfusion safety.Blood transfusion department should carry out precise blood transfusion matching with multiple antigens(RhCcDEe,Lea,M)for long-term transfusion patients,women,and patients with pregnancy or blood transfusion history,so as to reduce the incidence of unexpected antibodies and improve transfusion safety.
