My husband and I finally got pregnant with a child, so we pay more attention to this child. Now we are pregnant with 7 extra children. We often see other people's children born with mental retardation or something, so we are very afraid, so we want to have a check-up to see if our child has any problems.

Can retarded fetus be detected

First: generally 18-20 weeks of gestation to do B ultrasound can screen for fetal malformations, because at this time the various organs of the fetus have developed, B ultrasound is easy to see whether there are malformations. But some diseases of brain function or metabolic system can only be found after birth.

Second: the use of four-dimensional color Doppler ultrasound in obstetrics is mainly to observe the situation of the fetus, and to diagnose whether the fetus is abnormal. Down's screening can only detect one kind of mentally retarded children and Down's children. But more can not be detected during pregnancy. What's more, there are many intellectual disabilities caused by lack of oxygen at birth.

Third: Tang screening examination is the abbreviation of prenatal screening examination for Down's syndrome. The purpose is to determine the risk of fetal Down's syndrome by testing the blood of pregnant women. If the result of Down's screening test shows that the risk of fetal Down's syndrome is relatively high, further diagnostic examination - amniocentesis or chorionic villus examination should be carried out.
