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

For the health of the fetus, every pregnant woman should have a checkup on time during pregnancy. Throughout pregnancy, NT examination was performed in the first trimester, and Down syndrome was observed 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 results of Down's screening in pregnant women are abnormal, there is a great possibility that the fetus has Down's syndrome. If the screening results of Down syndrome in pregnant women are normal, it means that the probability of Down syndrome in the fetus is relatively small.

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

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 is likely to suffer from Down's syndrome, and the fetus is a child with Down's syndrome. (However, because the accuracy of Down's screening is not 100%, it is not excluded that the fetus does not have chromosome diseases. )

? If the results of Down's syndrome screening for pregnant women are low-risk, it means that the possibility of Down's syndrome in the fetus 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 fetus may have chromosome diseases, 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 great.

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 it is necessary to do non-invasive DNA or amniocentesis. If pregnant women are the third outcome and the critical risk, then for the sake of fetal health, pregnant women had better do further examination.

After the pregnant woman had Down's screening and non-invasive DNA, the doctor called to prepare herself 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, pregnant women should be psychologically prepared after further non-invasive DNA examination after receiving a phone call from a doctor, which means that the fetus is more likely to have chromosomal 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, that is to say, he will not receive a call from the doctor. You can't see it until you get the results. The doctor's notice is usually notified when there is an abnormal situation.

Of course, it does not rule out that doctors are not interesting. After all, doctors don't directly explain the abnormal non-invasive results. So pregnant women should not worry too early. You can ask clearly, or wait for the result, because pregnant women worry all day that anxiety is not good for the fetus.
