Pregnant women at the age of 40 are already considered elderly pregnant women, so it is even more important to pay attention to prenatal check ups. Especially the examination of Down syndrome requires special attention. However, pregnant women in this age group often worry about the high risk of Down syndrome screening. So, can a 40 year old pregnant woman, Tang Shai, pass?
Pregnant women over the age of 35 are considered elderly pregnant women. Relatively speaking, elderly pregnant women are prone to high-risk values during Down syndrome screening. Therefore, pregnant women over the age of 40 who undergo this screening will have a correspondingly lower pass rate. However, when there is a high risk in the initial screening, as an elderly pregnant woman, do not be too nervous, because the high risk in the screening does not necessarily mean that the fetus will have Down syndrome.
However, as an elderly pregnant woman, this examination cannot be ignored. Therefore, it is even more necessary to strengthen prenatal checkups and perform them according to the prescribed time. Especially if any abnormal conditions during pregnancy are detected, further examination through non-invasive DNA or invasive amniocentesis is needed to confirm, in order to avoid the birth of children with congenital abnormalities such as Down syndrome or chromosomal diseases. This can achieve optimal eugenics and child rearing as much as possible.
The time period for Down syndrome screening during pregnancy is generally arranged between 15-20 weeks, with 16-18 weeks being the optimal time for Down syndrome screening. Therefore, as an elderly pregnant woman, it is important to follow the hospital's arrangements and undergo Down syndrome screening in a timely manner.
