Many women prioritize their careers when they are young, so they get married later, which leads to the emergence of many elderly mothers. For elderly mothers, pregnancy can be more difficult and prone to many problems. Many people are not satisfied with Tang Shi who is over 35 years old? I am confused about this question, so I will introduce it to you below.
Actually, everyone's physique is different, so there may be differences in some examination results. According to the pregnancy examination, it is important to immediately understand the pregnancy status of the pregnant woman and the development status of the fetus, ensure the physical and mental health and safety of the mother and fetus, and ensure a smooth delivery. Therefore, examination is very important. The results of prenatal screening are related to many factors, so it is necessary to undergo timely examination.
The Down syndrome screening test is used to determine the risk level of Down syndrome in the fetus based on the pregnant woman's blood. Normally, pregnant women should undergo prenatal screening at 18-16 weeks. If the screening results are not satisfactory, meaning the prenatal screening value of blood testing exceeds 1/280, although this does not necessarily indicate fetal development, it is best to undergo other tests to confirm the diagnosis.
Tang Screen, also known as Tang Screen, is a detection method for the incidence of Down syndrome in children based on indicators such as maternal blood cells, reproductive period, age, weight, and gestational age. The screening time for early pregnancy is 12-13 weeks, and the optimal examination time is 12-13 weeks. The main goal of Tang screening is to avoid the risk of congenital infantile idiocy.
