In the process of prenatal examination, Down syndrome examination is also quite important. It can understand the function of the baby's brain and prevent various genetic diseases. If these examinations are ignored, it may be difficult to achieve results, and many abnormal injuries may occur, which is not conducive to the baby's adjustment. Is prenatal screening for Down syndrome?
Prenatal NT examination is used for Down syndrome screening. NT examination is usually conducted through the design of the nuchal translucency layer of the fetus to understand the development of the brain and chromosome diseases, and then targeted exclusion is carried out. The normal range for NT test values is usually between 1 and 3. Of course, the health level of each baby is different, so these test results need to be analyzed by doctors. If you feel that your baby has a recessive genetic disease, you can go to the hospital for fetal examination to understand whether there is a recessive genetic disease.
When checking NT, pregnant women should carefully choose the appropriate time, usually between 13 to 15 weeks of pregnancy. If the time is too early, the baby's brain has not yet fully developed, and the test results are not very accurate. If the time is too late, it can lead to more obvious symptoms.
Pregnant women can also learn about early chromosomal and genetic mutations in their babies through ultrasound. If a baby's genes show obvious mutations, more professional treatment methods should be used to control them as early as possible and stay away from the symptoms of Down syndrome.
