NT test is normal early don report has risk can not do non-invasive DNA

The NT test is normal, but the Early Down (early pregnancy screening for Down syndrome) report is risky and requires non-invasive DNA.
The NT test is only a preliminary screening test, and a normal test cannot confirm a diagnosis of Down syndrome. It is generally recommended to do non-invasive DNA or amniocentesis for early pregnancy Down syndrome screening for risk, which is more accurate. If non-invasive DNA is not done, the pregnant woman will be more worried during the whole pregnancy, and there is also a possibility of giving birth to a Down’s syndrome child, and once a Down’s syndrome child is born, it will cause a big burden to the family and the society.
Down’s syndrome screening in different trimesters, the joint screening method is not the same, the accuracy is not the same, so found that the Down’s syndrome screening risk should not be too nervous, it is recommended that further screening. Therefore, it is recommended that pregnant women listen to their obstetrician’s advice and undergo non-invasive genetic testing or draw amniotic fluid and cord blood to check fetal chromosomes as early as possible.
