On the off chance that any of these screening tests raise a warning, you can have an indicative test, for example, amniocentesis or chorionic villus inspecting (CVS), however these methodology do convey a little danger of premature delivery. Choosing whether to be screened, and which tests to have, is an individual decision: “A few ladies feel that the more data they have, the better they can set themselves up, or they may settle on some extreme choices,” says Dr. Davidson, taking note of that diagnosing Down disorder in utero helps specialists know to keep close tabs on whether your infant has any conceivably dangerous related issues, for example, innate coronary illness. “Yet, a few families decrease being screened in light of the fact that they feel the data wouldn’t change the course of their pregnancy.”
