研究目的:

孕早期无创胎儿血型诊断对预测胎儿新生儿溶血病(hemolytic disease of the fetus and newborn,HDFN)的发生风险具有重要意义。本项目探讨孕早期低浓度胎儿游离DNA(cell free fetal DNA,cff-DNA)提取方法,并不断优化,提高提取效率;以新生儿血型结果为金标准,对比得出的cff-DNA血型结果,判断cff-DNA检测血型技术的准确率,进行实验效果评价,包括实验方法的灵敏度、特异性及均一性等。最终获得孕早期胎儿血型基因检测的最优方法,早期筛选胎母血型不合的高危人群并进行早期干预。  

Objectives of Study:

The non-invasive diagnosis of fetal blood type in early pregnancy is of great significance in predicting the risk of hemolytic disease of the fetus and newborn. This project explores the extraction method of low concentration fetal free DNA in early pregnancy and continuously optimizes it to improve the extraction efficiency; Using the blood type results of newborns as the gold standard, compare the cff DNA blood type results to determine the accuracy of cff DNA blood type detection technology, and evaluate the experimental effect, including the sensitivity, specificity, and uniformity of the experimental method. The ultimate goal is to obtain the optimal method for genetic testing of fetal blood types in early pregnancy, and to screen high-risk populations with incompatible maternal and fetal blood types for early intervention.
