ABSTRACT
【Objective】 To analyze the RBC products returned by hospitals due to positive direct antiglobulin test (DAT), and explore measures to reduce the discarding rate of blood products and ensure the safety of clinical blood use. 【Methods】 The data of RBC products, which were returned by hospitals due to positive-DAT, in Hebei Blood Center from 2018 to 2020 were retrospectively analyzed. The donation time, hospital, gender of blood donors, donation times and DAT typing results were searched through blood donation code, input into the statistical software SPSS17.0, and analyzed by linear trend χ2 and Pearsonχ2. 【Results】 1)The discarding rate of RBC products due to positive DAT in 2018, 2019 and 2020 accounted for 0.15‰, 0.32‰ and 0.26‰, respectively, of the overall RBC collection. The total concordance rate was 89.94% by our retest. 2)The concordance rate of returned blood from secondary hospitals and tertiary hospitals was 78.26% and 91.78%, respectively (P<0.05), with the latter higher than the former. 3)No statistical significance was noticed in the DAT-positive blood by months(P>0.05). 4)The DAT-positive rate of female donors was higher than that of male donors, and that of first-time blood donors was higher than that of repeated and regular blood donors with statistical differences (P<0.05). 5)DAT-positive typing results was mainly due to IgG incomplete antibody. 【Conclusion】 In order to reduce the discarding rate of RBC products, it is suggested to strengthen the consultation before blood collection, encourage healthy males to donate blood and increase the proportion of regular blood donors. Meanwhile, the quality management of Transfusion Department in secondary hospitals should be further improved to ensure the safety of clinical blood transfusion.
