Abstract:
【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.
