Chorionic villus sampling is a test some pregnant women need to evaluate their child for hereditary problems. Losing the unborn baby rates are somewhat higher when the test is done with the cervix. The transcervical procedure is done by placing a slim plastic tube via the vagina and cervix to reach the placenta. Your health treatment provider uses ultrasound photos to assist lead the tube into the best area for sampling. A small sample of chorionic villus tissue is after that gotten rid of. You may be asked to put on a hospital gown. Tell your provider if you dislike iodine or shellfish, or if you have any other allergic reactions. This can be since: an antenatal testing test has suggested your child may be birthed with a problem, such as Down's syndrome, Edwards' disorder or Patau's disorder; you had a previous pregnancy affected by a hereditary problem; you have a family history of a genetic condition, such as sickle cell disease, thalassaemia, cystic fibrosis or muscular dystrophy. Throughout the test, a small sample of cells is eliminated from the placenta making use of 1 of 2 methods: transabdominal CVS, a needle is put with your belly; transcervical CVS, a tube or small forceps are inserted through the cervix. The CVS treatment is usually explained as being uneasy as opposed to agonizing, although you might experience some pains that resemble period discomforts for a day or 2 afterwards.
