Even if the risk of Tang screening is low, be careful, especially for high-risk pregnant mothers, don't save money in this regard
In today's era of rapid development of science and technology, people's living standards are constantly improving, and more and more people pay more attention to the cultivation of the next generation, especially the protection of contemporary women during pregnancy. Many mothers know that there is an item during pregnancy. The test is called Down's screening, and the test is designed to check for Down's syndrome in your baby. However, the downside of Down syndrome screening is that its accuracy is not high, only 60 to 70 percent, so even if the survey results show that the probability of a baby with Down syndrome is very low, it cannot be ignored.
After she became pregnant, Xiaomei paid great attention to her body and her baby. She would come to the hospital for an examination if any situation occurred. After hearing from her friend that she had Down syndrome, Xiaomei immediately came to the hospital for an examination. The baby is healthy and does not have a disease, so I can rest assured. Who knows that the baby will suffer from Down's syndrome when it is checked again soon, which makes Xiaomei's family very sad. It seems that Tang Si is really not "reliable", so what is Tang Si's inspection method and what are the defects?
Although the Tang screening test can have a detection effect on Down syndrome, the accuracy of this test method is very low. There are many mothers like Xiaomei who still suffer from Down syndrome after the test. Signs, which shows his inaccuracy, in fact, for the Tang screening test, there are two other inspection methods that are relatively accurate.
- Non-invasive DNA prenatal testing
The non-invasive DNA prenatal needle detection can increase the accuracy to 90%, and this technology is healthy and safe for the baby. By collecting the venous blood of pregnant women, using advanced scientific technology to determine the gene sequence in the blood, Finally, the genetic information of the fetus can be obtained by analyzing the data through a computer algorithm. For women, it is more suitable to perform this test in the twelfth week of pregnancy, because the DNA level in the female body will peak at this time, so it is most suitable, although this method has high accuracy But the price is very expensive, so many people will give up this option due to financial pressure.
- Amniocentesis
In addition to non-invasive DNA prenatal testing, a highly accurate method is amniocentesis. During the examination, the doctor will pass through the amniotic fluid of the pregnant mother to determine the specific condition of the baby's stainer, so as to know whether the baby is sick or not. The method has high accuracy, but its shortcomings are also obvious. During the inspection process, the pregnant mother needs to endure a lot of pain, and this process may lead to miscarriage. Even so, many high-risk Down syndrome Pregnant mothers still choose to have this surgery.
It can be seen that Down syndrome has a great impact on both the baby and the pregnant mother. In the process of examination, you must make a decision based on your own actual situation. You must not completely believe in Tang screening, nor can it be easily ignored. During pregnancy, the baby is in danger because of his estrangement. Parents want their baby to be healthy and healthy! how about you? What's your opinion on this?
