What is an integrated screening test for Down syndrome while you are pregnant?

ANSWER

You get two tests taken at different times. The first one is just like the first trimester combined test. Then, during weeks 15-22, you get another blood test called the “quad screen.” It looks for four different markers that could be signs of Down syndrome.

If you want to be a little more certain of the results, you’d get this test instead of just the first trimester combined test.
