Down syndrome screening is critical risk is not necessarily serious, need to be combined with non-invasive DNA screening, amniocentesis test results to determine.
Down’s syndrome screening is mainly to detect Down’s syndrome, and its result is only to assess the chance of the fetus having the disease, not a diagnostic test, so it is not possible to judge whether it is serious or not if the Down’s syndrome screening is a critical risk. Critical risk only means that the chance of the disease is higher, but it does not mean that the fetus is necessarily in trouble, so it may not be serious.
However, if the Down’s syndrome screening test is a critical risk and further non-invasive DNA screening and amniocentesis are done to confirm that it is Down’s syndrome, then it is a serious condition.
In conclusion, pregnant women who are at critical risk of Down syndrome need to strengthen their daily life management, go to the hospital for follow-ups on time, and may need to terminate their pregnancy if necessary.
