Prenatal non-invasive DNA testing is used to diagnose whether the fetus has chromosomal abnormalities. Through biological analysis of the test results, it can be determined whether the fetal development is abnormal. If the fetus has chromosomal abnormalities, it can cause changes in the DNA in the mother's body, providing theoretical basis for the final diagnosis. So is non-invasive prenatal DNA testing scientific?
Prenatal non-invasive DNA testing is scientific, which involves extracting 5 milliliters of peripheral blood from pregnant women and conducting biological analysis on genes to determine whether the fetus can develop more healthily. This examination is non-invasive and relatively inexpensive, making it a common survey method. This examination, as the main method for detecting chromosomal diseases, is the best way to reduce birth defects in babies. Early prenatal detection, diagnosis, and detection and resolution of problems are beneficial for both the fetus and the mother.
In addition, every couple may have chromosomal abnormalities in the process of pregnancy, which is accidental and has no signs before it occurs, but the incidence rate will increase with age. So during pregnancy, it is important to undergo prenatal check ups every month. If any abnormalities are found during fetal development, the pregnancy should be terminated as early as possible to avoid further harm to the body.
