For pregnant women, the health of the fetus is priceless. As long as the fetus can develop healthily, it is worth the effort for the pregnant woman to bear on her own. In order to timely understand the developmental status of the fetus, regular prenatal check ups are very necessary. For example, Down syndrome screening is one of them. When should Down syndrome be done in early pregnancy?
Down syndrome screening is one of the necessary examinations during pregnancy. The Down syndrome examination in early pregnancy, also known as NT examination, is recommended to be performed between 11-13 weeks of pregnancy. Early Down syndrome examination is determined by measuring the thickness of the fetal nuchal translucency. If the thickness of this zona pellucida exceeds 2.5mm-3mm, it indicates that there are health issues with the fetus, and it is recommended that pregnant women undergo a follow-up examination in a timely manner.
If you miss the Down syndrome test in early pregnancy, pregnant women should not worry too much. There is also a Down syndrome test that needs to be done in mid pregnancy. The mid-term Down syndrome test is conducted through blood sampling for laboratory analysis, and the test results are usually available after one week. Pregnant women need to be patient and wait. If there is a risk in the results of the mid-term Down syndrome examination, it is recommended that pregnant women undergo a re examination through amniocentesis.
In addition to NT examination and mid-term Down syndrome screening, amniocentesis is also an important method for screening fetal developmental abnormalities. Amniotic fluid aspiration requires the extraction of amniotic fluid from pregnant women for examination, therefore there are certain risks involved. It is recommended that pregnant women make cautious decisions. However, the results of amniocentesis are very accurate and have a relatively high clinical application rate.
