Chorionic Villus Sampling\u00a0(CVS) is a test that can detect certain problems in a fetus<\/span>, including genetic conditions and<\/p>\n chromosome<\/span> problems. CVS is done during early pregnancy, most often between the 10th and 13th weeks.<\/p>\n Chorionic villi<\/span>\u00a0are tiny finger-shaped growths found in the\u00a0placenta<\/span>. The chorionic villus cells have the same genetic material as the baby\u2019s cells. During CVS, a sample of the chorionic villus cells is taken. The sample is collected by putting a thin tube (catheter) through the vagina, or by inserting a long, thin needle through the belly. Ultrasound<\/span> is used to guide the catheter or needle to the right location.<\/p>\n CVS can detect many genetic conditions, including Tay-Sachs disease<\/span>\u00a0and\u00a0hemophilia<\/span>. It can also find chromosome problems, such as down syndrome<\/span>. CVS does not detect neural tube defects<\/span>.<\/p>\n CVS is done earlier in pregnancy than\u00a0amniocentesis<\/span> <\/a>(usually done at 15 to 20 weeks), and the results are available sooner. This gives patients more time to make decisions about their pregnancy, or plan for the future.<\/p>\n This informative video features William Goodnight, MD presenting an overview of prenatal evaluations and diagnostic tools.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" What is Chorionic Villus Sampling?
