Test Done During Pregnancy
One of the questions your OB may ask you is if you want an amniocentesis and/or CVS (chorionic villus sampling) test done--these two are the most common ones asked by your OB. What are they? They are tests done to see if your child has an extra chromosome (such as Down Syndrome--there are three forms of Down Syndrome).
Amniocentesis: a test used to determine if the child has Down syndrome, Sickle cell disease, Cystic fibrosis, Muscular dystrophy, Tay-Sachs and similar diseases, and certain neural tube defects such as spina bifida and anencephaly.
Slight risk of miscarriage involved but less than 1%.
CVS: A test used to determine if the child has a birth defect or genetic disease such as : Down Syndrome, Sickle Cell, cystic fibrosis, or other birth defects/genetic diseases. (However, I dislike both terminologies).
How it is constructed: Small cell samples are taken from the placenta.
This test carries a higher risk for miscarriage than the amnio test does.
We were asked this question. I have a step-daughter who has Down Syndrome. My hubby has 2-3 cousins with Down Syndrome as well (all brothers and sisters). I have a cousin with Williamson's Disease (much like Downs), a little sister who is mentally challenged (due to the umbilical chord being wrapped around her throat, causing lack of oxygen), and a great cousin with Autism. ADD and ADHD also run in my family but the tests cannot determine Autism or ADD/ADHD.
Did I have this test done? No? Why did I refuse?
The doctor asked me several times if I wanted the test, but I declined. Even with the slight chance of miscarriage, it wasn't a risk I felt comfortable taking. This is in no way trying to persuade mothers to do as I did. I have loved ones who are mentally challenged, and it doesn't bother me. If my child ended up with Downs, I would love my child the same. I also didn't want to spend my entire pregnancy worried (if I did find out they had a genetic illness) about my child, thus stressing out--as if I weren't already stressed enough.
My son was born with a narrow heart valve near his aorta. It connects the pulmonary valve and the pulmonary artery. Right now, it is not a major concern. It is just being monitored. It caused a lot of fatigue when he was a few months younger, thus placing him behind on a lot of motor skills--to which he is catching up rather quickly. Praise God. He also has webbed fingers. Two fingers on each of his hand are fused together. he cannot separate them but has mobility with both. He will be having surgery on his hands soon.
We weren't aware of these conditions until after birth. Do I regret not doing the tests? Not at all. My little boy is here. He is perfect, and I wouldn't change anything about him nor would I my daughter.
If you feel you need to get the test done, than go with your instincts.
