For the health of the fetus, every pregnant woman should have a check-up on time during pregnancy. Throughout pregnancy, NT examination was performed in the first trimester, and Down syndrome examination was performed in the second trimester.

Down's screening for pregnant women is used to check whether the fetus has chromosomal diseases, also known as Down's syndrome. If the pregnant woman's Down's screening results are abnormal, the fetus is likely to have Down's syndrome. If the screening results of Down's syndrome in pregnant women are normal, it means that the probability of Down's syndrome in the fetus is relatively small.

However, because the accuracy of Down's screening is not particularly accurate, when pregnant women are at risk in Down's screening results, they will further check the health status of the fetus and further check invasive DNA and amniocentesis.

We did Down's screening, and the non-invasive doctor called and told us to be mentally prepared. You got it?

The time for pregnant women to be screened for Down's syndrome is 15-20 weeks, during which pregnant women are screened for Down's syndrome to check the risk rate of fetal Down's syndrome.

If it is a high risk, it means that the fetus has a high possibility of Down syndrome, and the fetus is a child with Down syndrome. (But because the accuracy of Down's screening is not 100%, it is not excluded that the fetus does not have chromosome diseases. )

? If the result of Down's screening for pregnant women is low risk, it means that the possibility that the fetus has Down's syndrome is very low, and the possibility that the fetus is a child with Down's syndrome is relatively small. (But because the accuracy of Down's screening is not 100%, the possibility of fetal chromosomal diseases may exist, but the probability is very small. )

? If the results of Down's screening for pregnant women are critical risk, it means that the test results are in the low risk range, but they are critical and close to high risk.

The above three are the three results of Down's screening, of which the first low-risk result is considered normal, the second is abnormal, and the third is within the normal range, but the possibility of abnormality is high.

Therefore, if Down's screening for pregnant women is the first result and the risk is low, there is no need for further examination. If pregnant women are the second result, this is a high risk, and it is necessary to further check whether the fetus has chromosomal diseases and do non-invasive DNA or amniocentesis. If pregnant women are the third outcome and critical risk, then for the sake of fetal health, pregnant women had better have further examination.

After the pregnant woman had Down's screening and non-invasive DNA, the doctor called to prepare her psychologically. So it can be seen from here that the result of Down's screening for pregnant women should be high risk or critical risk.

However, after further non-invasive DNA examination, pregnant women will receive a phone call from doctors, so they should be prepared psychologically, which means that the fetus is more likely to suffer from chromosome diseases.

Because in general, it is still non-invasive for pregnant women to do Tang screening. If the result is normal, then the general doctor will not call to make psychological preparation, which means he will not receive a call from the doctor. You can only see the result when you get it. The doctor's notice is usually notified when there is an abnormal situation.

Of course, it does not rule out that doctors have no meaning. After all, doctors will not directly explain that the results of non-invasive tests are abnormal. So pregnant women should not worry too much too early. You can ask clearly, or wait until you get the result, because if pregnant women worry about anxiety all day, it is not good for the fetus.
