Which of the two tests are better? Or are recommended ? Amniocentesis or cvs (chorionic villus sampling )? No past history of any health problems.

It depends.: CVS is generally thought to have a slightly higher miscarriage rate than amniocentesis, but this may not be the case everywhere. For mor e information check this link: http://www.babycenter.com/0_chorionic-villus-sampling-cvs_328.bc?page=4#articlesection8 ...Read more

Chorionic villus sampling (cvs) can test for what all diseases?

Chorionic villus sampling (cvs) can test for what all diseases?

Chromasomal or: Genetic disorders. Can detect missing or extra chromasomes, i.e. 47 instead of 46 present in down syndrome. Can test for genetic, inherited disorders like cystic fibrosis or tay-sachs disease. ...Read more

What are amniocentesis, chorionic villus sampling and blood/saliva test screening used for? Abortions?

What are amniocentesis, chorionic villus sampling and blood/saliva test screening used for? Abortions?

Prenatal diagnosis: Cvs and amniocentesis are used to discover chromosomal abnormalities in the fetus. They are also used to diagnose genetic diseases, such as cystic fibrosis, that some people are at risk for. Blood and saliva screening tests are used to find out if parents are at risk for a baby with certain genetic diseases. ...Read more

At what stage is chorionic villus sampling done?

At what stage is chorionic villus sampling done?

10-12 weeks: Chorionic villus sampling (cvs) obtains cells from the fetoplacenta for testing at 10-12 weeks of pregnancy, amniocentesis obtains fetal skin/urine cells at 16-18 weeks. Higher risks for miscarriage (2-3% for cvs, <0.5% or negligible for amnio) balance against the cvs advantage of testing before a women "shows, " preserving the privacy of pregnancy (testing). ...Read more

Risk: Risk of pregnancy loss with cvs and amniocentesis are equivalent. That's been shown by four different studies. In experienced hands the loss rate is something like 1 in 1600. ...Read more

Do I have to see a specialist to get a chorionic villus sampling cvs ordered?

Do I have to see a specialist to get a chorionic villus sampling cvs ordered?

YES!!: You need a specialist, a maternal-fetal expert, also called a perinatologist to do this. Your OB can order it, but you need a specialist with experience & skills to minimize risks to your fetus. ...Read more

Someone here please explain the difference between chorionic villus sampling and amniocentesis?

Someone here please explain the difference between chorionic villus sampling and amniocentesis?

Placenta vs fluid: Cvs can usually be done earlier and involves obtaining placental tissue for chromosome analysis. This is done by needle biopsy either through the cervix or abdomen. Amniocentesis is obtaining amniotic fluid for testing also by needle aspiration. Both are done with ultrasound guidance, cvs slightly riskier with bleeding & cramping, both safe to do, both done by mfm docs. I hope that helps. ...Read more

Is it ok to skip the amnio or chorionic villus sampling procedure? Is it required to have it at my age of 38?.. What will be the consequence for me?

Please discuss with: Your OB as this should be explained by your OB , i assume you will be getting an integrated screen which is an early test to r/o downs t-18 , spinal bifida and now there are new blood tests to r/ o those problems like harmony and there are 3 others, so the majority of my pts do not get an amnio unless one of those tests is abnormal so u need to speak with your ob. ...Read more

Can I do chorionic villus sampling in the first trimester?

Can I do chorionic villus sampling in the first trimester?

Yes: Chorionic villus sampling (cvs) is done in the first trimester between 10-12 weeks. It has a slightly higher risk of miscarriage associated with it than an amniocentesis- which is usually done after 15 weeks- because it is performed earlier in the pregnancy. Blood tests and a nuchal translucency ultrasound are noninvasive genetic screening options. ...Read more

What is the definition or description of: ultrasound-guided chorionic villus sampling?

What is the definition or description of: ultrasound-guided chorionic villus sampling?

Looks at chomosomes: Chorionic villus sampling enables a doctor to remove a small sample of the tissue that surrounds the early sac of pregnancy. This, then, allows the study of the chomosomes - for early diagnosis of conditions such as down syndrome (an extra chromosome #21). It is done with ultrasound guidance at roughly 11 weeks of pregnancy. Amniocentesis is a procedure done later in pregnancy for the same reason. ...Read more

Why would a pregnant person need chorionic villus sampling (cvs)?

Why would a pregnant person   need chorionic villus sampling (cvs)?

Genetic testing: Chorionic villous sampling represents one of the earliest available methods to accurately diagnose genetic abnormalities such as down's syndrome. While most, if not all, of these defects are not curable, it does give the patient the earliest opportunity to decide on whether to continue the pregnancy. ...Read more

Top caliber maternal: Fetal centers especially those with medical school affiliations should either perform chorionic villus sampling or be able to refer you to a center that does. There is a 1% risk of miscarriage & very minor risk of infection spotting pain or crampiing. Advantage over amniocentesis is that it can be performed earlier in pregnancy (10 -13 weeks after your last menstrual period). ...Read more
