RESUMEN

【Objective】 To analyze the distribution of unexpected antibodies in tumor patients retrospectively and explore the clinical significance. 【Methods】 Unexpected antibody screening was performed on inpatients with blood preparation and blood transfusion in our hospital from January 2004 to December 2022, with 1 176 cases tested positive, and the types of unexpected antibodies and distribution characteristics were statistically analyzed. 【Results】 Unexpected antibodies were screened in 1 176 cases, with the positive rate at 1.05% (1 176/111 483). The unexpected antibodies were mainly anti-E 16.33%(192/1 176), anti-M 7.99% (94/1 176), anti-Mur 5.70% (67/1 176) and anti-Lea 4.76% (56/1 176). Among the 1 176 cases, gastrointestinal tumors accounted for 27.99% (329/1 176), gynecological tumors accounted for 24.84% (292/1 176), respiratory tumors accounted for 16.67% (196/1 176) . 【Conclusion】 The influencing factors of unexpected antibodies in tumor patients were disease type, blood transfusion history and blood type. Therefore, it is necessary for clinical departments to carry out unexpected antibody screening and perform Rh blood type matched transfusion for tumor patients to avoid alloantibody production.

RESUMEN

Objective To evaluate the influence of blood transfusion or pregnancy on blood cross-matching results.Methods 1 000 specimens with blood transfusion or pregnancy history were collected and performed the blood group typing,blood cross matching,irregular antibody screening and identification by the micro-gel method with the specimens of first time transfuse blood and without pregnancy history as the control.The inconsistency rate of positive negative blood grouping,unqualified rate of blood cross matching and the positive rate of irregular antibody were compared between the two groups by the t-test.The causes influen-cing the blood cross-matching results were analyzed.Results The inconsistency rate of blood cross-matching in the blood transfu-sion or pregnancy group was significantly higher than that in the control group(P 0.05);the positive rate of irregular antibody screening in the blood transfu-sion or pregnancy group was also significantly higher than that in the control group(P <0.05),indicating that the main causes in-fluencing blood cross matching was the existence of irregular antibodies in the patients in vivo.Conclusion Blood transfusion or pregnancy may stimulate the body to produce the irregular antibodies.Therefore the irregular antibody screening should be per-formed before blood transfusion and blood without corresponding antigen will be selected for transfusion according to the antibody identification results for ensuring safe and effective blood transfusion.
