The birth of non-invasive DNA has made significant contributions in clinical practice. It can prevent birth defects in newborns and help many families conceive healthy babies. Can non-invasive DNA be used to treat neural tubes?
Non invasive methods cannot examine neural tubes. During mid pregnancy, doctors may recommend that pregnant women go to the hospital for Down syndrome screening. Due to different genetic factors, the results of Down syndrome screening may vary among different women. If Down syndrome screening reveals neural tube abnormalities, many women would like to have a non-invasive examination of the neural tubes, but non-invasive methods cannot detect neural tubes. Neural tube defects are examined through ultrasound, not diagnosed through amniocentesis like non-invasive methods, so non-invasive methods cannot see neural tubes.
Experienced women will find that non-invasive DNA testing is not a routine prenatal examination. Non invasive DNA is mainly suitable for elderly mothers. Elderly mothers refer to women who are over 35 years old during pregnancy and have a positive Down syndrome screening result. Non invasive DNA testing is also required for those who have placenta previa or placenta previa that is too low to be examined through invasive methods during pregnancy.
Nowadays, it is advocated to promote eugenics and child rearing. If a doctor tells the mother through prenatal examination that the baby's development is not very good, then the mother should follow the doctor's advice and not force herself to do it according to her own ideas, which is not beneficial for the baby's future growth.
