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.
Is it a boy or girl? Amniocentesis and chorionic villus sampling are used mainly for testing to determine the sex of your unborn child. Blood/saliva testing is used for so many other conditions they can't begin to begin to be listed here.

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...

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

CVS and Amnio. A cvs is done earlier in pregnancy and involves getting tissue from the placenta. An amniocentesis is done later in pregnancy. It involves getting amniotic fluid from the gestational sac. Chromosomal abnormalities can be found by both techniques. An amniocentesis can also check for neural tube defects. A genetic disease, such as cystic fibrosis can be diagnosed by either technique. Read more...
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...

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...
