摘要
目的：了解脐带血在新生儿ABO溶血病诊断中的应用价值。方法：对531例临床怀疑为新生儿ABO溶血病的患儿进行血型鉴定与新生儿溶血病三项试验,即改良直接抗人球蛋白试验、游离抗体试验、抗体释放试验。结果：使用脐带血检测的新生儿ABO溶血病的阳性率为90.3%、出生后1～3 d组阳性率为71.6%、4～7 d组阳性率为29.9%、8～15 d组阳性率为21.1%、16～30 d组阳性率为0。结论：新生儿ABO溶血病实验室检出的阳性率以脐带血组最高。且随着患儿出生时间的延长阳性率下降。
Objective：To investigate the application and demand of using the blood of umbilical cord in diagnosing the case of the newborns who′s infected with ABO-Haemolytic Disease（ABO-HDN）.Methods：Three tests were performed on 531 new-born babies who′s suspected of being infected by ABO-HDN.Including direct antiglobulin testing（DAT）,free antibodies testing,antibody release testing.Results：The group of the newborn who was testing using the blood of umbilical cord had a positive rate of 90.3%,positive rate of the babies within the group of born after 1~3 days was 71.6%,group of 4~7days were 29.9%,group of 8~15days were 21.1%,the group of 16~30days was zero.Conclusion：The group of the newborn testing using blood of umbilical cord has the highest positive rate of ABO-HDN.Furthermore,the rate decreases as the time gets longer.
