摘　　要：目的:探索用低效价O型全血及A型血浆建立战备血库的可行性。方法:应用Galileo全自动血型分析仪检测O型献血者样本的IgM抗A、抗B抗体效价和A型献血者样本的IgM抗B效价,选取抗A、抗B效价同时低于128的O型献血者纳入战备流动血库,抗B效价低于128的A型血浆和抗A、抗B效价同时低于128的O型全血纳入战备实体血库。结果:共选取1452个O型献血者,检测抗A/B抗体效价,两种抗体效价均分布于512以下,且样本分布峰值均处于效价4,两种抗体效价>128的样本比例均较低;两种抗体效价存在明显正相关(r=0.383),且IgM抗A效价高于IgM抗B效价的样本比例较高;同时满足IgM抗A和抗B抗体效价<128的献血者1335人(91.94%),可纳入流动血库。检测512例A型献血者抗B效价,结果显示,随着抗体效价的增高,样本比例逐渐降低;抗B抗体效价<128的献血者占99.8%,仅有1例不符合纳入条件。结论:O型献血者全血符合低效价标准的比例较高,A型献血者血浆几乎均符合低效价标准,提高了突发情况下的血液供应率。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 1452 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.1335(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.
