Abstract:
Objective:To explore the feasibility of establishing combat readiness blood bank with low titer group O whole blood and group A plasma.Methods:The Galileo automatic blood analyzer was used to detect the titers of IgM anti-A and anti-B antibodies in the samples of group O blood donors and IgM anti-B titer in the samples of group A blood donors.Group O blood donors with antibody titers below 128 were selected and included in the mobile blood bank for combat readiness,group A plasma with anti-B titer lower than 128 and group O whole blood with antibody titers below 128 were included in the combat readiness entity blood bank.Results:A total of 1 452 group O blood donors were selected,and the anti-A/B antibody titers were detected.Both antibody titers were distributed below 512,and both peak values of sample distribution were at titer 4.The proportion of samples with titers＞128 for both antibodies was relatively low.There was a significant positive correlation between the titers of the two antibodies(r=0.383),and the proportion of samples with IgM anti-A titer higher than IgM anti-B titer was relatively high.1 335(91.94％)group O blood donors with IgM anti-A and anti-B antibody titers＜128 could be included in the mobile blood bank.The anti-B titer of group A blood was detected in 512 cases and the results showed that as the antibody titer increased,the proportion of blood donors gradually decreased.99.8％of group A blood donors had anti-B antibody titer less than 128,and only one case did not meet the inclusion criteria.Conclusion:The proportion of group O blood donors whose whole blood meet the low antibody titer standard is high,and almost all plasma of group A blood donors meet the low titer standard,which improves the blood supply rate in emergencies.
