A procedure that involves taking a biopsy from the placenta to test the fetus for genetic abnormalities. It is usually carried out under ultrasound scan at about eleven weeks of pregnancy. The placenta has the same genetic make-up as the baby. There is a 2-3% risk of the procedure causing a miscarriage.

Chorionic villus sampling (CVS) is a diagnostic test carried out in early pregnancy, usually between Week 10 and Week 12 of pregnancy. Some of the cells which line the placenta, the chorionic villi, are removed through the cervix or abdomen using a needle or catheter. The cells are tested to see whether the developing fetus has Down's syndrome or o...

(CVS) A test performed between 10 and 12 weeks to look at cells in the placenta by inserting a thin flexible tube (catheter) into the uterus through the vagina or by inserting a needle through the belly into the uterus. Similar to an amniocentesis, a CVS procedure can be used to find chromosomal birth defects, such as Down syndrome.

Biopsy of a small sample of placental tissue, carried out in early pregnancy at 10–12 weeks' gestation. Since the placenta forms from embryonic cells, the tissue obtained can be tested to reveal genetic abnormality in the fetus. The advantage of CVS over amniocentesis is that it provides an earlier diagnosis, so that if any abnormality is ...
