A critical value for Down syndrome screening in early pregnancy means that the fetus is at risk for Down syndrome, a chromosomal disorder that requires further non-invasive DNA testing or amniocentesis to determine the health status of the fetus.
There are low-risk, medium-risk and high-risk conditions for Down syndrome screening, and the critical value indicates the possibility of high risk, which means that the fetus is likely to have Down syndrome, and further non-invasive DNA test or amniocentesis is needed to improve the non-invasive DNA test or amniocentesis, to determine clearly whether this chromosomal abnormality disease is likely to occur.
If a pregnant woman finds an abnormality during early pregnancy screening for Down syndrome, she needs to go to the hospital in time and improve the examination under the doctor’s guidance to clarify the health status of the fetus, and if there is an abnormality, she needs to be induced if necessary.
