发生在绒毛取样的细胞遗传学检测的不一致性证实了沿着滋养层-胚胎轴存在着一种细胞核型可变性的可能。尽管存在可变性,但大量研究证实绒毛取样有很高的准确率,是早期诊断染色体异常的有效手段。
Inconsistency in cytogenetic testing of villus sampling confirms the possibility of a nuclear karyotype along the trophoblast-embryonic axis. Despite the variability, a large number of studies have confirmed the high accuracy of villus sampling and are an effective means of early diagnosis of chromosomal abnormalities.
