Dad-to-be: Hello, your baby only has a trisomy risk of 2 1. This data shows that there are certain risks. Please don't worry, it's also a question of probability, which doesn't mean there is something wrong with your baby. The accuracy of Down's test is only about 60%, and 40% of pregnant mothers have some problems with the data, but only 0. 1% of the people who have detected problems do have problems. Therefore, most mothers who have problems with Down's examination are healthy after further examination. Factors affecting Down's test value include parents' long-term exposure to chemicals, parents' long-term exposure to radioactive substances such as computers, and taking anti-abortion drugs in the first trimester. According to your test probability, your baby is more likely to get sweet baby than other children. So for the happiness of you and your wife, for the happiness of the baby, it is necessary to do this sheep puncture examination. Don't bet on the happiness of your family. In addition, pregnancy needs a happy mood. If it is normal, your wife can better conceive your baby. I believe you already know that cooked food is light and cooked food is heavy. Don't worry, sheep puncture is a very mature examination. It is said that there is a risk of 0.5%-0. 1%, but the actual risk is far below this probability. I wish my mother a smooth pregnancy and a healthy baby!
