Results: 72-100% of peripheral blood lymphocyte metaphases or inter-phases, 60- 70% of amniocyte interphases, and 95-99% of chorionic villus cell interphases showed expected signals.
结果：72～100％外周血淋巴细胞中期相或间期核、60～70％羊水细胞间期核、95～99％绒毛细胞间期核显示预期信号。
Examples of diagnostic tests include amniocentesis and chorionic villus sampling.
的例子，诊断测试，包括羊膜穿刺术和绒毛取样。
Objective: to compare the relative safety of two methods of chorionic villus sampling.

Treatment Some forms of CAH can be detected in prenatal tests like amniocentesis or chorionic villus sampling.
治疗一些类型的先天性肾上腺增生性肥大能够运用诸如羊水诊断或绒毛膜取样的产前检查被发现。
The next step in improving the current test will include analysis of DNA from direct chorionic villus sampling or amniotic fluid to further reduce the TAT.
接下来，进一步减少TAT的改进措施包括从绒毛膜绒毛或羊水直接取样用于DNA分析。
We were told that there was a 99% likelihood that the results of the blood test were accurate, and that my wife needed a CVS test (chorionic villus sampling) to confirm these results.
我们被告知，血液测试结果的准确性有99%，同时我的妻子需要做一个CVS测试（绒毛膜取样）以确认这些结果。
However, conventional methods of obtaining fetal tissues for genetic analysis, including amniocentesis and chorionic villus sampling, are invasive and constitute a finite risk to the unborn fetus.
然而，常规的获得遗传学分析的胎儿组织的方法是有创伤的并且是对胎儿有一定的风险，这些方法包括羊膜腔穿刺和绒毛活检被称为侵入性产前诊断。
