In The Politics of Autism, I explain:
When a pregnancy is under way, doctors can detect certain kinds of disorders, but neither amniocentesis nor any other prenatal test can currently tell us whether a fetus will become autistic. Suppose that such a test did exist. “The best case use of a prenatal test at the moment would be if you could say to a parent, your child has got an 80 percent likelihood of autism and so once the baby's born, we would like to keep a close eye on that child in case they need extra support like speech therapy or social skills training or some sort of behavioral approach,” says leading autism scientist Simon Baron-Cohen. But would the “best case use” be the most common? When amniocentesis indicates Down Syndrome, most mothers choose abortion. A study of autism parents in Taiwan found that just over half would abort if a prenatal test indicated that their next child would be autistic. We cannot be sure what the figures would be if such tests were available in the United States, but it seems likely that a large share of autism pregnancies would end in abortion.
At CBS, Julian Quinones and Arijeta Lajka report a dramatic drop in Down Syndrome births in Iceland.
Since prenatal screening tests were introduced in Iceland in the early 2000s, the vast majority of women -- close to 100 percent -- who received a positive test for Down syndrome terminated their pregnancy.
While the tests are optional, the government states that all expectant mothers must be informed about availability of screening tests, which reveal the likelihood of a child being born with Down syndrome. Around 80 to 85 percent of pregnant women choose to take the prenatal screening test, according to Landspitali University Hospital in Reykjavik.

Using an ultrasound, blood test and the mother's age, the test, called the Combination Test, determines whether the fetus will have a chromosome abnormality, the most common of which results in Down syndrome. Children born with this genetic disorder have distinctive facial issues and a range of developmental issues. Many people born with Down syndrome can live full, healthy lives, with an average lifespan of around 60 years.
Other countries aren't lagging too far behind in Down syndrome termination rates. According to the most recent data available, the United States has an estimated termination rate for Down syndrome of 67 percent (1995-2011); in France it's 77 percent (2015); and Denmark, 98 percent (2015). The law in Iceland permits abortion after 16 weeks if the fetus has a deformity -- and Down syndrome is included in this category.The story quotes a pregnancy counselor:
"We don't look at abortion as a murder. We look at it as a thing that we ended. We ended a possible life that may have had a huge complication... preventing suffering for the child and for the family. And I think that is more right than seeing it as a murder -- that's so black and white. Life isn't black and white. Life is grey."
