Summary: During pregnancy, we need to do many examinations, the three most important of which are: 4D color ultrasound, Tang screening examination and sugar screening examination. Among these three examinations, we all know the four-dimensional examination and the Tang screening examination. The first is to rule out abnormalities, and the second is to screen pregnant mothers for gestational diabetes. Do you know about Tang screening test?

The Down syndrome screening test is a screening test for Down syndrome. Mainly, blood tests are performed on pregnant women to determine the probability of their fetus having Down syndrome. If the chance is high, further testing is done to confirm, such as amniocentesis or chorionic villus testing. The reason why this examination is important is because it involves the relationship between the fetus having Down syndrome.
With this disease, 60% of fetuses will be miscarried in the first trimester. Even if they are lucky enough to be born, they will have obvious congenital characteristics, such as mental retardation, special facial features, growth and development disorders or malformations, etc.
Therefore, once a fetus develops Down syndrome, it is a tragedy for the child and the family. Especially if the following types of pregnant mothers are not careful, they are more likely to give birth to a baby with \”Down syndrome\”. Don\’t take chances and harm your baby.
Pregnant women with a family history of Down syndrome
Down syndrome is a congenital disease. If a pregnant mother has a child with Down syndrome at home, she must be vigilant. My neighbor\’s aunt gave birth to a child with Down syndrome. However, because the medical conditions were not good 20 years ago and her family was poor, she did not have a check-up and did not know what caused it.
Therefore, she wanted to have another child so that she would have someone to rely on when she was old. As a result, the second child was born again with Down syndrome. After suffering two blows in succession, she no longer dared to have children. Now over fifty, she worries about her two children every day. It is said that my aunt\’s sister also gave birth to two children, one of whom also had Down syndrome.
If someone in the pregnant mother\’s family, including her husband\’s family, has Down syndrome, don\’t take any chances. Just in case, you can do a chromosome test before pregnancy and a Down syndrome screening 15-20 weeks after pregnancy.
Pregnant mothers who were severely irradiated during pregnancy
Radiation during pregnancy affects both the pregnant mother and the fetus. The biggest impact is the possibility of fetal malformation or Down syndrome. Therefore, it is recommended that pregnant mothers stay away from radiation and not be exposed to radiation-containing medical examinations.
A pregnant mother reported that she had an abdominal X-ray during her first trimester but was unaware she was pregnant. At that time, the doctor said that the radiation must be present, but would it cause fetal malformations?The shape is still difficult to determine, so let her decide whether she wants the fetus or not.
Soon after, she suffered an unexplained miscarriage. Although it is not known whether the fetus in this pregnant mother\’s womb has Down syndrome, it is certain that severe radiation is not good for the fetus. Therefore, in order to avoid giving birth to a child with Down syndrome, pregnant mothers should try to stay away from radiation.
Pregnant mothers over 35 years old
Older pregnant mothers have more adverse symptoms during pregnancy, such as gestational hypertension, diabetes, etc., and are also prone to congenital malformations and Down syndrome. Therefore, pregnant mothers over 35 years old should pay more attention.
Research shows that the probability of a pregnant mother under the age of 25 giving birth to a child with Down syndrome is 1/2000, and this probability will increase significantly with age, while a pregnant mother over the age of 35 will give birth to a child with Down syndrome. The probability of having a child with the disease is as high as 1/300. Therefore, older pregnant mothers must pay attention to Down syndrome screening during pregnancy, and if necessary, undergo amniocentesis or chorionic villus examination to determine whether there is a possibility of giving birth to a baby with Down syndrome.
