Which is Better: The Down Syndrome Screening Test or Non-invasive Prenatal Testing?

Tang screening refers to Down's syndrome screening, and noninvasive refers to noninvasive DNA prenatal testing. Compared with Tang screening, noninvasive DNA testing is better and can better judge the condition of the fetus. Tang screening refers to the screening of Down syndrome in fetuses during pregnancy, mainly through blood sampling from pregnant women. However, this method cannot achieve a 100% detection rate and may have false positives. Non-invasive DNA prenatal testing has the same role as Tang screening, but it can detect more chromosomal abnormalities and has a higher accuracy rate than Tang screening. Therefore, it is better for pregnant women to choose noninvasive DNA prenatal testing for prenatal examination, which can better understand the growth and development of the fetus. Specific situations still need to consult a doctor at the hospital. At the same time, they should prepare well before the examination, rest well, eat healthily, maintain a pleasant mood, and develop good living habits. After the examination, keep the skin around the needle hole clean, avoid strenuous activities, and if there are any abnormalities, go to the hospital for examination as soon as possible and seek treatment under the guidance of a doctor to avoid affecting physical health.
