During pregnancy, mothers usually need to go to the hospital for various examinations, including B-ultrasound to check the development of the fetus, listen to the fetal heart rate to see if the fetal movement is normal, abdominal palpation to determine the position of the fetus, and all preparations are made to ensure the safe delivery of the fetus. So what are the three levels of prenatal screening during prenatal check ups?
Prenatal tertiary screening is actually a three-dimensional color ultrasound examination, which should be very common. Pregnant mothers will undergo this examination at 25 to 28 weeks. Because during this period, various organs of the baby's body have already grown out, doing this 3D ultrasound is to see if there are any abnormalities in the organs, and also to perform screening for abnormalities.
The third level prenatal screening is to screen for any genetic problems in the fetus, while Down syndrome screening involves extracting serum from the mother's blood for testing various indicators to see if they exceed the standard. Finally, combining multiple results, it calculates any inappropriate aspects of fetal growth and development, and whether there are any risks at birth.
Usually, it is to screen for fetal abnormalities. Nowadays, severe air pollution, various radiation, and lifestyle habits can greatly affect the growth of babies, such as cartilage disease. The main purpose is to examine various parts of the fetal body, such as the fetal head, limbs, bladder, heart, lungs, liver, kidneys, etc., which may have defects. If there are developmental problems, early intervention is necessary.
