Q&A: Why CVS/amnio?

What exactly do diagnostic tests like CVS and amniocentesis look for? Do I need to have these tests?

Re: What exactly do diagnostic tests like CVS and amniocentesis look for? Do I need to have these tests?

The Bump Expert

Both amniocentesis and CVS (chorionic villussampling) are diagnostic tests for chromosomal and genetic disorders such as Down syndrome and cystic fibrosis. Amnio also can detect neural tube defects such as spina bifida. About two or three of every hundred babies is born with such a defect, and most occur in the first three months of gestation. Because of the slightly increased miscarriage risk (more about this later), neither test is offered routinely. But, if your baby is at increased risk of chromosomal or genetic defects or earlier screenings suggest potential problems, expect to discuss the option of testing with your doc.

Our doctor said there is a risk involved with an amniocentesis. I think we're going to avoid it.

My husband and I have decided against prenatal testing outside of U/S. We're low-risk for genetic factors and have had healthy children. We also have no intention of ending the pregnancy over a problem with our child and don't feel like it is worth the risk of miscarriage or that I need to be poked at anymore! :)

When do I need to have these tests? I would like to have them.

With my 1st child and with this pregnancy, I will not have the testing done. My family is totally pro-life and no matter what the tests said, our pro-life decisions would not change, one bit. Every chile is a blessing from God!

re: Q: Why CVS/amnio?

I think CVS is only necessary if you are high risk. I would still do the first trimester and second trimester screening though (even if you are not high risk). I am planning on sequential screening. That gives a result after the first trimester screening with NT and blood work.We don't have any known family risks, but just knowing will be helpful. A lot of people think "why test if you are not going to do anything about it", but I would do something. I would not terminate, but I would prepare myself with knowledge and help in my community to bring a special needs child into the world.

I completely agree with Blessed by God!'s comment! The CVS/amnio tests are not nessecary! They carry a lot of risks to the baby. Why would you put yourself and your baby through that? If God forbid there is something wrong what difference will it make? You will still love that baby with all your heart and soul.

Special needs children require a lot of extra care and money. This continues well into adulthood. Some people do not have the financial stability to take care of a child for 50 years. It also takes so much strength for parents to do this. Down syndrome is not just mental; most children with down syndrome also have problems that put them in pain and force them to have surgeries. I don't think I could handle knowing that I could have stopped my child from being in pain. However, I don't think I will get the CVS/amnio because I am young enough to not have much of a risk.

Great feed back! I'm going around and around on this one. We are high risk (paternal mental retardation) but know that we wouldn't terminate the pregnancy regardless. Jexxie is dead on about the responsibility and cost of special needs (we know first hand from my sister in law). It's hard to weigh the the benefit of being able to prepare ourselves both mentally and financially before the baby arrives against the risk of miscarriage. So... no final decision yet.

I had an amnio with my first pregnancy and I will never do it again. There are other ways. I am having a 3D ultra sound done this time to test for chromosomal defects and abnormalities . When I had the amnio done, not only was it extremely painful but I was terrified by the 7 inch needle. They also hit my son with the end of the needle on the arm and he jumped so harm that it scratched him. I WILL NEVER DO IT AGAIN!!! NEVER!

re: Q: Why CVS/amnio?

My fiance and I are considering the tests. I am unsure of the risks in our genes but we feel in the situation we are in, it would be best to know and if needed, be prepared. My Mom runs a company that does day/night excursions and events for disabled ppl from DS to MS to Autism. We know the costs and life changes that accompany disabled children. I think it would both beneficial for our child and for us as parents to know.

re: Q: Why CVS/amnio?

These tests are available not just for you to make a abortion decision, if something may be wrong. You need to be prepared if there is such a problem. Having a child with a disability will take special precautions you need to prepare for long before you bring your baby home. Consider the welfare of your child, and make the right decision.

re: Q: Why CVS/amnio?

Is CVS necessary? This is my 3rd child. My other children are healthy and I'm still very young. I don't have insuance and must pay for everything up front. I was told these tests are extremely expensive. Any advice?

re: Q: Why CVS/amnio?

OK! I NEED HELP! I just posted a question about CVS and how I have no insurance and must pay for EVERYTHING! Neither myself or my husband have insurance through our work, and medicaid denied us due to "high income" which our income really isn't that high. No individual ins. company's will take me b/c of "pre-existing pregnancy" Any advice? This situation has put A LOT of stress on me. PLEASE HELP!

re: Q: Why CVS/amnio?

I guess I would talk to your doctor about whether or not you should have those extra tests done. If they think that you are in fine health, and there is no history of any of these disabilities in your past, then she may tell you to forgo it, I don't know. I would relax at the moment, you aren't doing yourself any favors by getting worked up about this!! :)

re: Q: Why CVS/amnio?

One other comment in regards to why you would want to know...my doctor mentioned that it is important for the hospital to know before you give birth so that they can have the right people of staff for your delivery. Many downs babies have cardiac problems and it is good to have a specialist on immediately after birth...so it is not only to be mentally prepared as parents, but for the hospitals to be able to give your baby the best care possible.
