If the result of the Down’s syndrome screening test is a critical risk for trisomy 21, there is no way to confirm whether or not the child can be born, because the Down’s syndrome screening test is not very accurate and the diagnosis must be made through the next step of the test. Amniocentesis is preferable. It is risky, but it can be the final method of diagnosis. Non-invasive DNA can be done. If the non-invasive DNA test is normal, the baby is perfectly fine to have. However, if the non-invasive DNA is abnormal, an amniocentesis is required as the final diagnosis and is the most accurate way to determine whether to terminate the pregnancy.
