Rh阴性血型4例的家系调查

Survey of the Pedigree of 4 Cases of RH Negative Blood Type

目的通过4例Rh阴性血型的家系调查分析,发现该家庭中Rh阴性血型遗传的特殊性。方法利用血清学和相关实验室检查,找出该家系中Rh阴性血型遗传的规律性。结果发现在1例父亲为Rh阴性、母亲为Rh阳性血型的家庭中,出现了4例Rh阴性血型。结论在父亲为Rh阴性血型家庭中,如果母亲为Rh阳性(D/d)型,则子代出现Rh阴性血型的概率较高。

[ Objective ] To discover the genetic uniqueness of RH negative blood type through the analysis of the pedigree of 4 cases of RH negative. [ Methods] Serological and related laboratory tests were carried out to identify the family genetic regularity of RH negative blood type. [ Results] 4 cases of RH negative were found in the family of one Rh negative （ the father） and one Rh positive （the mother）. [ Conclusion] If the father is Rh negative and the mother is Rh positive, the probability of Rh negative is quite high in their offspring.
