We all know that every stage after pregnancy needs to go to regular examinations, and it should be necessary to go to the hospital to do relevant pregnancy confirmation tests, blood draws or b ultrasound to confirm the fetus from the beginning of pregnancy. It should be very nervous to go to the hospital for examination when you first know that you are pregnant, one is that you don't know what to do for the confusion, and the other is that you are at a loss for whether the unknown life is safe or not, and you are both nervous and excited.
It is recommended not to miss any examination items, this is a life but no joke can be made, each stage has a related examination items, but also very necessary doctors and pregnant mothers are also hoping that everyone can "pass the customs" at once. In particular, the two most important levels are the main items to ensure that your baby is developing properly. If both of these items can be passed safely, and the inspection results are no problem, then the subsequent obstetric examination does not have to worry too much, and the normal waiting for delivery is OK!
Level 1: Down's Child Screening
The first level is about 15-17 weeks pregnant. This test is more critical, the normal value is generally more than 1000 denominator, if the denominator is less than 1000, then an amniocentesis is needed to further check for genetic abnormalities. Finally, it can be determined whether it is a fetus with Down syndrome, and now the test is used as a free screening program in many top three hospitals, which can also be seen that the importance of this project is recognized by the state. Later, combined with the examination of Tang Siev, it is also necessary to check an NT value, which is also more able to judge the accuracy of the pregnancy test.
As for some pregnant mothers, they have some doubts, is it not to do Tang screening early, the accuracy rate will be relatively low? The test takes a certain month to do, the accuracy rate of 15-17 weeks can reach about 70%, and there is generally no need to do non-invasive DNA if the screening is no problem. Through this genetic barrier, the mother will also be much more at ease.
2. 3D or 4D color ultrasound
Three-dimensional and four-dimensional color ultrasound are for the examination of large-scale teratology, which is different from ordinary B ultrasound, generally need to make an appointment, it is mainly to check whether the fetus's body and organs have developmental abnormalities or defects, exclude fetal developmental malformations, early detection and early prevention and early treatment. The time to do three/four-dimensional color ultrasound should be about 24-26 weeks, and it is generally necessary to make an appointment when it is 17 weeks pregnant.
Do not advance to 20 weeks before the earliest, because the premature examination of the fetal body is still developing, not yet fully developed, so the derating effect is not ideal and accurate; at the latest, not later than 28 weeks later, the fetal volume in the third trimester is too large, it is inconvenient to check, even if the detection of problems is more difficult to deal with. So it is best to make an appointment for a good three/four-dimensional time according to the doctor's recommendation and check it on time. If the result is ideal, then you can basically rest assured.
