Is CVS more likely than amniocentesis to cause a miscarriage?
Yes it is, but only slightly. Sadly, about two in every 100 women experience a miscarriage as a direct result of CVS (RCOG 2006). That's compared with about one in every 100 women after an amniocentesis (RCOG 2005: 2).

CVS testing is available to any pregnant woman, but it's optional rather than routine. Women who are over 35 (and therefore at increased risk of carrying a baby with a chromosomal disorder) may choose to have CVS.

CVS is an outpatient procedure performed by a specially trained doctor. If you decide to have a CVS, an ultrasound scan will be arranged before the test to establish the stage of pregnancy, the best time for doing the CVS and the best technique to use.

A ~ is done at around 11 weeks. A needle is passed through the uterine wall into the placenta and a small sample of the placenta removed. In both cases the sample is sent to a genetic laboratory where foetal cells are cultured and the chromosomes analysed.
Who gets tested?

~ (chorionic villus sampling)
The ~ test is used to detect defects associated with chromosomes (Down's syndrome) or genes (including sickle-cell disease, thalassaemia, haemophilia, cystic fibrosis, and muscular dystrophy) and is offered to pregnant women after week 10 of their pregnancy, ...

~ (chorionic villus sampling) -- a test where a small bit of the chorion surrounding the baby is sampled with a tube going up through the cervix. Testing this can reveal genetic problems with the baby and tell its sex.

How is ~ performed?
~ may be offered to women who are at increased risk for chromosomal abnormalities or have a family history of a genetic defect that is testable from the placental tissue. ~ is usually performed between the 10th and 12th weeks of pregnancy.

How is ~ done?
Chorionic villi cells can be collected in one of two ways. During the test, your doctor may: ...

~ is a diagnostic test usually performed at 10 to 12 weeks of pregnancy for women who have had an abnormal screening test. In comparison, amniocentesis is usually performed at 15 to 18 weeks. About 1 in 200 to 1 in 300 women undergoing ~ will miscarry.

~ is performed between 10 and 12 weeks of pregnancy. In ~, the doctor inserts a needle through the abdomen or inserts a catheter through the cervix to reach the placenta. The doctor then takes a sample of cells from the placenta.

~ is an early pregnancy test and the results don't take long to come through. If you decide to terminate your pregnancy, it may be less traumatic than if you have to make the decision later on.
There's a small risk of miscarriage, estimated to be between 0.5 and 2 per cent.

~ is different from another prenatal test called amniocentesis (also called amnio). Amnio is performed a little later in pregnancy. Talk to your provider about having ~, amnio or other prenatal tests.

~ has the disadvantage of being an invasive procedure, and it has a small but significant rate of morbidity for the fetus; this loss rate is about 0.5 to 1% higher than for women undergoing amniocentesis. Rarely, ~ can be associated with limb defects in the fetus.

~ can help identify such chromosomal problems as Down syndrome or other genetic diseases such as cystic fibrosis, Tay-Sachs disease, and sickle cell anemia. ~ is considered to be 98% accurate in the diagnosis of chromosomal defects.

~ and amniocentesis are, at present the only tests available which can make a definite diagnosis of disabling conditions in babies whilst they are still in the womb.

~ (see-vee-ESS) - See chorionic villus sampling.
cystic fibrosis(SIS-tik fye-BROH-siss) - Also called CF. A disease that parents can pass on to their children. It affects breathing and digestion.

Blood tests for: blood group; anaemia; hepatitis B virus; rubella immunity and syphilis
Other possible blood tests for: Hepatitis C; HIV; Thalassaemia, iron studies, vitamin D ...

~ takes a sample of cells from the placenta, to look at the foetus' DNA. It is offered between weeks 10 and 13 and can detect: ...

~ -- see Chorionic Villus Sampling
Cyst -- A fluid-filled structure.
Doppler -- In ultrasound, a technique used to detect and evaluate moving structures. It is usually applied to the evaluation of blood flowing in vessels.

~ increases the risks of fetal loss by about 1.2 percent over the risk without the procedure. There have been concerns about the procedure itself causing malformations of legs and arms. This risk seems to be about 0.03 percent and is probably greater the earlier the procedure is performed.

~ - Chorionic Villae Sampling
An alternative to amniocentesis that can be done earlier in the pregnancy. It is a biopsy of the placenta that is used to check for genetic abnormalities in the fetus.

How does ~ works?
A doctor will take a tiny piece of tissue from your placenta via a needle inserted into your tummy. There is a very small risk of miscarriage associated with this test, estimated at 1-2 percent.

~ (Chorionic villus sampling) is one test that detects chromosome and other genetic abnormalities, usually between the 9th and 14th weeks of pregnancy. Learn more about prenatal screening and diagnostic testing.

Choironic villus sampling (~) - A test done at 11-13 weeks of pregnancy to determine if the fetus has normal chromosomes. Can diagnose a chromosomally abnormal baby earlier than an amnioscentesis (done at 15-18 weeks and you get results in 10-14 days).

Chorionic villus sampling (~) - this test may be performed between 10 and 12 weeks to test for genetic / chromosomal abnormalities such as Down's syndrome, sickle-cell anaemia, thalassaemia, cystic fibrosis, Huntingdon's chorea, muscular dystrophy and haemophilia.

Chorionic Villus Sampling (~)
This diagnostic test is usually performed between 8 and 11 weeks gestation, sometimes as late as 13 weeks. This is generally a test for people who have a high risk of genetic abnormalities. Test results are available within 7 to 14 days.

Chorionic villus sampling (~). A prenatal test that involves taking a sample of some of the placental tissue. This tissue contains the same genetic material as the fetus and can be tested for chromosomal abnormalities and some other genetic problems.

Chorionic villus sampling (~) - This is a procedure in which a sample of the chorion (the membrane surrounding the baby) is taken for testing. The needle is inserted into the placenta but the amniotic sac is not disturbed. The test is used for checking for any genetic abnormality in the fetus.

Chorionic Villus Sampling (~) as an alternative to amniocentesis because it can be done earlier (between weeks 10 and 12). Like the amniocentesis, the test takes about half an hour and may be uncomfortable.

Chorionic villus sampling (~) screens for the same birth defects as amniocentesis but earlier in the pregnancy (between 10 and 12 weeks). ~ tests material from the uterus, which is collected by sending a tube through the vagina and cervix.

Chorionic villus sampling (~) is a prenatal test used to check for genetic disorders in the fetus such as Tay-Sachs disease, cystic fibrosis, and chromosomal abnormalities like Down syndrome. A ~ test will not reveal all birth defects.

Possible dangers from ~ include infection, maternal or fetal bleeding, spontaneous abortion, Rh immunization, birth defects, and perforation of the membrane surrounding the embryo. ~ is generally considered to be slightly riskier than amniocentesis.

Amniocentesis and its cousin Chorionic villus sampling (~) are both tests which involve taking a sample of material from inside the womb and running tests to check for any genetic or chromosomal abnormalities in the fetus.

Chorionic Villus Sampling (~) - Samples of tiny projections on the placenta, called chorionic villi, are taken to look for defects in the foetus.

Chorionic Villus Sampling (~) at 10-12 weeks: A thin tube (catheter) is threaded usually through the vagina and cervix into the uterus and a small sample of the placental tissue is obtained. This tissue can be "grown" to determine the exact number of chromosomes of the fetus.

You can usually choose between a chorionic villus sampling (~) at 9 to 11 weeks or an amniocentesis at 15 to 16 weeks. (Miscarriage risks are a bit higher with the ~ test.) If the results are positive, further tests or counseling can be arranged, says Maria Hayes, M.D.

Chorionic Villus Sampling (~)

Removal of cells that line the placenta, the chorionic villi, through the cervix using a catheter or through the abdomen using a needle. The material obtained may be tested for Down syndrome and other disorders.

Chorionic villus sampling (~) - A procedure that removes a small sample of chorionic villi cells from the placenta where it joins the uterus, to test for chromosome abnormalities such as Down syndrome
Circumcision - A procedure done on male infants that removes the foreskin from the penis ...

chorionic villus sampling (~) ~ If necessary this test is performed between 10 and 12 weeks of pregnancy and can indicate the same chromosomal abnormalities and genetic disorders as amniocentesis can. It also can detect the baby's sex and risk of spina bifida.

More involved diagnostic tests such as chorionic villus sampling (~) and amniocentesis can diagnose specific genetic disorders by examining a sample of cells obtained from the placenta inside the woman's uterus to map the baby's chromosomes (or genes).

There is also a must to undergo prenatal tests such as chorionic villus sampling (~) during pregnancy week 9 to detect chromosomal abnormalities and many genetic disorders. This test is advisable to women who are over 35 years old, have family history of genetic illness.

Chorionic villus sampling (~) - Diagnostic test done early in pregnancy. A biopsy of tissue is taken from inside the uterus through the abdomen or the cervical opening (through the vagina) to determine abnormalities of pregnancy.

Chorionic villus sampling (~)
A biopsy of the placenta through the abdominal wall or by way of the vagina and uterine cervix at nine to 12 weeks of gestation to obtain fetal cells for the prenatal diagnosis of genetic disorder.

Chorionic Villus Sampling (~)-A few cells from the placenta are removed during pregnancy in order to examine the baby's chromosomes and look for some genetic diseases.

- That if you elect to have an amniocentesis, ~ or External Cephalic Version during pregnancy you should be given an Anti-D injection as a preventative.

If you're over 35 or are worried about genetic problems you may want to think about screening or diagnostic tests. The nuchal translucency ultrasound and ~ test both check for abnormalities and need to be booked early.
