chorionic villus sampling

1 These might include chorionic villus sampling (CVS) or amniocentesis, which screen the baby for congenital disorders.

2 Currently, determining a fetus's genome requires either amniocentesis, in which a needle is inserted through the mother's abdomen into the amniotic sac, or chorionic villus sampling, in which a piece of placenta is removed.

3 But that is not the case in a place like Texas, where a current six-week ban (likely to soon be followed by a near-total ban) would render moot the option of even an early prenatal diagnostic test such as chorionic villus sampling, which is typically administered at 10 weeks or later.

4 Diagnostic tests, generally performed through invasive procedures, such as chorionic villus sampling and amniocentesis, also focus on specific disorders and confer risk of pregnancy loss that may inversely correlate with access to high-quality care.

5 Both amniocentesis and chorionic villus sampling (another invasive procedure that collects placental cells from within the womb) carry a 1 percent risk of miscarriage.

6 In the 1980s, doctors started using chorionic villus sampling, or CVS, an analysis of placental tissue that offers a diagnosis earlier in pregnancy.

7 The high-probability patients are offered a more invasive diagnostic test using DNA either from the fetal cells floating in the amniotic fluid (amniocentesis) or from placental tissue (chorionic villus sampling).

8 Deborah and Ariel Levy sued for damages, alleging the physician who had performed the chorionic villus sampling procedure had mistakenly removed maternal tissue instead of fetal tissue.

9 Objective To determine value of chorionic villus sampling ( CVS ) in early diagnosis of severe thalassemia.

目的探讨绒毛活检在重型地中海贫血早期诊断的应用价值.

10 Confirmation with chorionic villus sampling ( CVS ), amniocentesis or other testing is still necessary.

仍然需要用绒毛膜取样 ( CVS ), 羊水检查等其他检查确认.
