摘要:目的 分析以微柱凝胶法全自动血型系统鉴定婴儿脐带血ABO及Rh(D)的血型可行性。 方法 选取500份婴儿脐带血标本，采用试管法和微柱凝胶法进行ABO和Rh(D)血型鉴定。 结果 在鉴定婴儿ABO和Rh(D)血型时，试管法正反定型符合率84.2%(421/500)，微柱凝胶法符合率98.4%(492/500)，且微柱凝胶法的正定型结果全部正确。RHD检测结果两法一致。 结论 微柱凝胶法检测婴儿的ABO和Rh(D)血型时优于传统试管法，在常规血型检查应推广应用。

    Abstract:Objective To differentiate ABO and Rh(D)blood groups of umbilical cord blood of infants with automatic determi-nation system of micro-column gel agglutination assay(MGAA). Methods Five hundreds of umbilical cord blood samples were collected and the blood group of ABO and Rh(D)were differentiated with traditional tube test and micro-column gel agglutination assay. Results The coincidence rates of ABO blood group typing and reversed typing by MGAA and traditional tube test were98.4%(492/500)and84.2%(421/500) ......
