ABSTRACT
【Objective】 To analyze the blood samples sent by hospitals in Shenzhen to solve ABO cross-match incompatibility during 2011 to 2020, so as to find corresponding solutions to improve the efficacy of blood transfusion. 【Methods】 The clinical data of 1 770 cases of cross-match incompatibility in our laboratory from January 2011 to December 2020 were collected and reviewed. The causes of cross-match incompatibility were analyzed, the types of unexpected antibodies were determined. The overall incidence of antibodies was evaluated by statistical method of classified variables. The safety of blood transfusion was safeguarded by ABO homotype plus cross-matching compatibility. 【Results】 1) The 1 770 samples, presenting cross-matching incompatibility, involved 956 patients. The average number of cross-matching per patient from 2011 to 2015 was 1.32(307/232), which increased from 1.27(103/81) in 2016 to 2.23(286/128) in 2018, and remained stable in 2019 and 2020. 2) Among 956 patients, auto-and/or allo-antibody in plasma were yielded in 90.38%(864/956), including auto-antibody plus alloantibody in 42.26%(404/956), solo auto-antibody in 20.71%(198/956) and solo allo-antibody in 27.41%(262/956). Up to 20 kinds of specific allo-antibodies were detected, belonging to 8 blood groups. Among them, 70.82%(551/778) were Rh blood group, such as anti-E(37.15%)>anti-c(20.95%)>anti-C(5.27%)=anti-e(5.27%)>anti-D(2.19%), followed by MNS [11.40%(112/778)], Kidd [5.66%(44/778)], Leiws [3.21%(25/778)], Duffy [1.80%(14/778)], Diego [1.03%(8/778)], P1 [0.39%(3/778)] and H [0.26%(2/778)]. 3) 86%(37/43) of multiple transfusion recipients, aged below 20 years old, were thalassemia, and 1-4 kinds of allo- and/or auto-antibody were yielded. 【Conclusion】 The cross-matching incompatibility were mainly caused by allo- and/or auto-antibodies, which may be induced by blood transfusion, pregnancy or autoimmune diseases such as autoimmune hemolytic anemia.Those suspicious blood samples in clinical should be sent to blood group reference laboratory for further determination, in order to ensure the safety and efficacy of blood transfusion.
