Thanks for that Adnedarn, I too stand corrected. That really makes abortion a much more complex issue when the chances of the baby having the disorder or not aren't 100% determined.
Nepenthusiast, a little more information on the abortion subject.... The triple screen was the first indication that there may be a problem. And this test is offered at about 4 months into the pregnancy. So if you opt for it, by about 4.5m into the pregnancy is when you find out the first indication that there may be a problem. Keeping that in mind, I think "late term abortion" is defined as 14-20weeks... So by the time parents know there might be a problem, it is generally already considered late term.... Definitely something to keep in mind when thinking about abortion as simply a Yes/No answer, it's quite a bit more complex than that. Not saying if there were a test that could say YES your kid has down syndrome, would mean he/she should be aborted IMHO.
