Pregnant women nowadays need to undergo some necessary examinations after pregnancy, which are essential in prenatal check ups. There are many tests for prenatal check ups, and the content of each test item is different. Compared to before, there is an additional non-invasive DNA test. So, can non-invasive methods detect neural tube defects?
Non invasive examination mainly refers to non-invasive DNA testing, which can detect neural tube defects. If the fetus has neural tube abnormalities, there are many tests that can detect them, such as four-dimensional color ultrasound, which can also detect problems with fetal neural closure, especially abnormalities in neural tube closure.
The examination of amniocentesis is also to detect the possibility of neural tube defects in the fetus. For fetuses, once there is an abnormality of neural tube closure, it can cause a congenital occurrence. The main clinical manifestations of neural tube malformation are. Abnormal development of the spine and skull may occur.
The content of non-invasive DNA testing is quite extensive, and the main purpose of the test is to detect the chromosomes of the fetus and see if there are any abnormal chromosome numbers. However, non-invasive DNA testing cannot be the final test result. To know the final result, it mainly depends on amniocentesis.
