Is there a DNA test for Down syndrome during pregnancy?

ANSWER

DNA is what your genes are made of, and some DNA from an unborn baby ends up in the mother’s blood. This test looks at that DNA for signs of Down syndrome. You can get this test starting at 10 weeks, but it’s mainly used for women who are more likely to have a baby with Down syndrome.
