摘　　要：目的研究静脉输注免疫球蛋白对患者输血相容性检测的影响。方法将2017年3月1日2020年12月31日本院输血科检测的56例意外抗体筛查试验阴性但与同型献血员主侧交叉配血不相合、且有免疫球蛋白输注史的患者作为研究对象,采用微柱凝胶法检测ABO及RhD血型、意外抗体筛查、交叉配血、直接和间接抗人球蛋白试验以及酸放散试验。结果输注免疫球蛋白后与同型献血员主侧交叉配血不相合的患者,与O型献血员主侧交叉配血均相合。其中,2例患者因输注免疫球蛋白而出现一过性ABO血型正反定型不相符;37例A型患者红细胞放散液中检测出了IgG类型抗-A;2例B型患者红细胞放散液中检测出了IgG类型抗-B;17例AB型患者红细胞放散液中有3例检测出了IgG类型抗-A和抗-B,14例只检测出了IgG类型抗-A;随机检测3个批次静脉输注用免疫球蛋白,IgG抗-A效价为3264,IgG抗-B效价为816。结论静脉输注用免疫球蛋白中含有IgG类型的抗-A和抗-B,部分非O型患者输注后可导致ABO血型正反定型不符、同型献血员主侧交叉配血不相合,此时建议输注主侧交叉配血相合的O型洗涤红细胞以保障临床输血的安全有效。Objective To study the effect of intravenous immunoglobulin(IVIG) on the detection of blood transfusion compatibility in patients. Methods 56 patients, submitted to our Hospital from March 1, 2017 to December 31, 2020, were enrolled as the research objects. They had negative unexpected antibody screening, major crossmatch incompatibility with the same blood type donors, and had a history of IVIG infusion. ABO and RhD blood groups typing, unexpected antibodies screening, crossmatch, direct antiglobulin test, indirect antiglobulin test, and acid elution test were all conducted by microcolumn gel method. Results After IVIG infusion, the initially major crossmatch incompatibility with the same blood type donors turned into compatiblity with O-type donors. Among them, 2 patients had transient discrepancy in ABO forward and reverse blood typing due to the IVIG infusion. IgG anti-A were detected in the red blood cell elution of 37 A-type patients;IgG anti-B in 2 B-type patients;3 cases of IgG anti-A+anti-B and 14 cases of solo IgG anti-A in 17 AB-type patients. 3 batches of IVIG preparations were detected randomly, IgG anti-A titer was 32-64, and IgG anti-B titer was 8-16. Conclusion The discrepancy in ABO forward and reverse blood typing and major crossmatch incompatibility with the same blood type donors may occur after non-O type patients received IVIG, which contains IgG types of anti-A and anti-B. In this situation, it is recommended to prepare major crossmatched O-type washed red blood cells to ensure the safety and effectiveness of clinical blood transfusion.
