Tang screening is an essential examination in pregnancy test, but why can Tang's baby be born after Tang screening?

Pregnant mothers are often told that Tang screening is risky and doctors should ask for non-invasive DNA or amniocentesis. As a result, nothing happened. This process makes pregnant mothers jumpy, especially affecting their mood, and it is also quite painful when waiting for the test results. I wanted to induce labor at that time. B-ultrasound and NT are abnormal. My family thinks it is too small, so I can see everything. Finally decided to do amniocentesis. It happened that during the Chinese New Year, it was reported that I waited for 20 days 1 month. On receiving the report, the hospital called.

One is common chromosome examination, and the other is comprehensive examination. Many chromosome diseases can be screened, but the price will be higher. Of course, this is also the reason why many pregnant mothers are entangled. This 10 feels so long! All kinds of worries have finally come to fruition, but what we can wait for is the danger of Tang Screen. The doctor said it should be non-invasive, but the cost is very high, more than 2000 yuan. Let me think, I said, then do it! After this time, I waited 15 days.

Down's screening is high risk, while amniocentesis is close to 98% normal, while Down's screening is critical risk and needs to be non-invasive. Therefore, many treasure mothers think that doing Down's screening will increase their sense of insecurity, and that kind of panic is estimated to be known only by those who have experienced it. But on the contrary, when the child they gave birth to went to the hospital for examination more than a month later, the doctor saw that his face was a little abnormal and told them that the child might have a problem. Results With the growth of children's age, the characteristics of Down syndrome became more obvious. At first glance, it's baby Don. ?

About 3.5-8% of them were positive by Down's screening, but there was no fetal abnormality. Different staff and different test methods may affect the indexes of blood test, so many hospitals still recommend pregnant women to have amniocentesis. Healthy children, wasting money, these pregnant women may have limited cultural quality, can't keep up with the development of the times, the news is blocked, and they don't understand and pay attention to Down syndrome, which largely determines that they can't or won't do Down's screening.
