Whats the integrated test? Does it look for all birth defects?

I'm not sure! I am just not sure what the "integrated test" is. And this is not a criticism of you at all. The words in medicine and especially in genetics are crazy hard to understand properly. And sometimes their meanings change! i would be very pleased if you could find out a bit more about this test, including the lab that performs it, and ask once more. Btw, no test or procedure finds all birth defects.
