How often should pregnant women undergo major fetal anomaly screening?

Pregnant women should pay attention to their physical health during pregnancy. Once they find that they have a disease, they need to take appropriate measures to treat it in time to ensure their health and avoid problems with their bodies. In particular, they should pay attention to the examination of fetal malformations. So how often should pregnant women undergo major fetal malformation examinations? Let me introduce my views on this issue to you below.

Generally speaking, early pregnancy tests to confirm pregnancy are not formal prenatal tests. Formal prenatal tests usually begin around 12 weeks of pregnancy, which cover a wider range and include many test items. Therefore, prenatal examinations must be started 12 weeks after the pregnancy is confirmed, and a maternal health handbook should be established to record the results of each prenatal examination for future analysis.

The prenatal check-up conducted at 12 weeks of pregnancy is called the initial prenatal check-up, which is of great significance for subsequent prenatal checks. After 13 weeks of pregnancy, you enter the second trimester and the number of prenatal checkups will increase. Therefore, pregnant women should arrange a prenatal checkup schedule in advance. Under normal circumstances, a prenatal checkup will be conducted every four weeks from 13 to 28 weeks of pregnancy. The examination items include four-dimensional color ultrasound, Down syndrome screening and other fetal abnormality examinations, so be sure to arrange each examination well.

After a woman reaches the second trimester, her body will undergo great changes, and prenatal examinations in the late pregnancy become even more important. From 29 to 36 weeks, a check-up should be arranged every two weeks. After 36 weeks until the fetus is born, it is necessary to pay attention to weekly prenatal check-ups. At this time, the development of the fetus has been finalized, so follow-up monitoring is necessary to see if there are any abnormalities in the pregnancy and to deal with them correctly as soon as possible.

For high-risk pregnant women such as older mothers and those suffering from certain diseases, the importance of prenatal examinations is much higher than that of other pregnant women of normal age. They need more examinations and the number of examination items will increase. They should always reflect their physical condition. It is best to do it once in the early, middle and late stages of pregnancy to ensure their own health and that of the fetus.

Through comprehensive and systematic prenatal examinations, we can effectively understand the developmental posture and status of the fetus in the mother's body, so that we can have a clear idea of ​​the situation when delivery comes, ensuring a safe and smooth delivery process. Regular prenatal checkups can provide timely information about the condition of the fetus and the pregnant woman in each pregnancy cycle. If there are any abnormalities, remedial measures can be taken in time to reduce the difficulty of subsequent pregnancies and remove obstacles.

The above is my opinion on this issue. Pregnant women should pay attention to physical examinations during pregnancy to avoid problems with the fetus that may cause danger to the fetus. Therefore, timely examinations are needed to ensure the safety of the fetus and avoid problems with the fetus' body.
