Blood test & down syndrome

[bunniiebaybii]

OK I had my blood test done a few weeks ago for down syndrome. So they say no news is good news. But I was still curious about if there can be a chance for a child to come out with the condition if my other children didn't. What are the chances of that happening? Is it genetic? Its not in my family or my husbands but can it still happen?

The test produces both false negative and false positive results at times. The only sure way to know BEFORE delivery is an amnio or cvs, which are both pretty risky. Also, there is still a SMALL chance that it could even be wrong. These tests are 98-99% accurate. With both tests, the biggest risk is miscarriage. Infections, Premature labor and/or rupture of membranes are also both risks to consider. The American Pregnancy Association emphasizes that there is a 1-2% chance of having false results.

They told me that there was a high risk of my baby having ds from my blood work. But my nt scan was normal. So I opted for an amnio. Which camee back normal 46 chromosomes and confirmed my babys gender. Girl. It just depends on the person. If you are worried give your.doctor a call and ask them for the results.

It depends on your age, as to your risk factor, the older you get the higher the risk, there is a form of downs that is genetic but most of the time its due to the age factor, and the quality of the egg. In australia they do a combination test, which is a blood test 5 days before you have your scan. They like to do the scan right on 12 wks over here, then they combine the bllod test result, your scan measurement and your age and give you yourodds of carrying a bub with downs, if its anything from 1:300 and under, over here they advice more invasive testing either a cvs or amnio, which or course carries its own risks but give you a definite answer

I think I should read up on it. Because just in case, I should know what to do if there is still a chance. I plan to have one more child but not for a few years after this one ill be over 30 so if there is that chance I would know more about it. Thanks :)

Although Down syndrome is a genetic condition, the most common form is not inherited. According to the National Down Syndrome Society (NDSS), 1 in every 800 to 1,000 babies is born with Down syndrome... this info is from body and health canada.com... So yes even with your previous children.... every pregnancy is different

From what i know about testing is that it is never a guarantee regardless of what the % is that they say that the baby will have down syndrome... a friend of mine had a high chance... pretty much they were telling them their child WOULD have DS but their baby didnt! so no matter what the blood work shows, it isnt a definite outcome... this being said... it does give the couple time to prepare and research down syndrome in case they do have a baby with this condition so it can help to know what your odds are...

And i know once you pass 30 your chances do increase (which i see you havent) but that being said, lots of women are waiting longer to have children so the estimated odds in statistics would be increased do to this...
