Being screened by Tang is said to have a high risk of receiving text messages. Is the result accurate if it is non-invasive

At this time, Tang called me directly from the hospital. I asked something, but the doctor didn't say anything, so he asked me to come to the hospital as soon as possible. I'm scared. I don't know how to describe it. After going to the hospital, the doctor told me about Down's son with a high-risk examination report, and then asked me to go to the city hospital for amniocentesis.

Finally, I checked the specific content of Down's screening online, knowing that the accuracy rate would not be very high, and then I saw that others recommended non-invasive examination items, so I did it, and the final result was low risk. Although this process is very hard and costs a lot of money, it is worthwhile for the baby's health.

So, if you get a text message saying it's high risk, is the result accurate if you do it non-invasively? The accuracy of Down's screening is about 80%, and its test results are affected by the height, weight, age, menstrual period and gestational age of pregnant women, which means that if one of them is abnormal, the accuracy of Down's screening results will be lower.

The accuracy of non-invasive DNA is 99%, and its examination can only be completed by taking the blood of pregnant women. Many high-risk pregnant women and elderly pregnant women also choose non-invasive, because non-invasive is simple, risk-free and accurate.

But non-invasive can't be the final diagnosis result. If the fetus really has a problem and needs to terminate the pregnancy, the hospital will not accept it. The hospital only recognizes the results of amniocentesis, and the accuracy of amniocentesis can reach 100%.

The price of non-invasive surgery is relatively expensive, about 2,000 yuan, and it is still cheap in some places. After subsidy, several hundred yuan is enough, while the cost of amniocentesis is relatively expensive, about 3,000 yuan.

Summary:?

Personally, I think it is better to do non-invasive screening for Down syndrome if pregnant mothers don't have Down syndrome at home or are not high-risk elderly people, but irregular menstruation or abnormal weight lead to screening for Down syndrome. If there is a case of Down syndrome at home and the pregnant woman is in poor health, then do amniocentesis directly.
