What does Tang Sie mean by low risk? Do you need further examination?

The screening test in the Tang Dynasty is a very important screening test during pregnancy, and expectant mothers must pay full attention to it. If the Tang screening test data shows low risk, does the expectant mother need further examination?

What does Tang Sie mean by low risk? Do you need further examination? The low risk of Tang screening is the data of Tang screening test for expectant mothers, which means that expectant mothers have passed the Tang screening test, which means that the probability of fetal down syndrome is relatively low. However, the Tang screening test can not clearly indicate whether the fetus has it, but only the probability that the fetus has it. After most expectant mothers pass the screening test in the early Tang Dynasty, they can safely raise their babies until about 24 weeks of pregnancy, and make an appointment for a four-dimensional color Doppler ultrasound examination in the hospital, without any further examination.

If the expectant mother is an elderly woman over 35 years old, or someone in the family, or the expectant mother fails the nt examination, then the data of the expectant mother's Tang screening examination can not accurately explain the problem. Doctors will advise expectant mothers to make an appointment for amniocentesis or non-invasive DNA examination at the hospital around 16 weeks of pregnancy. Because these tests can more accurately determine whether the fetus has chromosomal abnormalities, and can also determine whether the fetus has Down syndrome.

Noninvasive DNA is to determine whether the fetus has chromosomal abnormalities by extracting and detecting the venous blood of expectant mothers. Because there are some fetal DNA in maternal blood, detecting maternal venous blood can indirectly understand fetal genes. Amniocentesis, on the other hand, is to extract amniotic fluid for testing to determine whether the fetus has developmental malformation. This is a more direct inspection and the data obtained is more accurate. However, doctors must puncture the mother's abdomen and uterine wall to extract amniotic fluid. The accuracy of these two tests is significantly higher than that of Down's screening, and of course the cost is relatively expensive.

Conclusion Most expectant mothers don't need further examination after passing the screening test in the early Tang Dynasty, but only need routine prenatal examination as required, while elderly women and expectant mothers with family history need amniocentesis or non-invasive DNA examination to judge whether there is any problem in fetal development more accurately.
