During pregnancy, for the sake of both the pregnant woman and the baby's health, it is advisable to regularly visit the hospital for prenatal check ups to avoid any problems that may not be remedied in a timely manner. During pregnancy checkups, the examination of the placenta is an important part of the examination process. If there are problems with the placenta, mothers may also feel uneasy. So, what does it mean to see bright spots in the placenta?
It is normal to see bright spots in the placenta, which may be due to fetal bones or placental calcification during scanning. Doctors often judge the maturity of the placenta by the number of bright spots on it. As long as it is within a controllable range, mothers do not need to be too nervous. During the placental examination, attention should be paid to whether there is umbilical cord entanglement around the neck. Attention should be paid to daily sleeping posture when the umbilical cord wraps around the neck.
One of the important tests in prenatal checkups is prenatal screening. What are the common prenatal screening tests?
1. Abnormality inspection. Firstly, a prenatal screening is conducted at 20 weeks of pregnancy, which is completed through ultrasound. The main focus is on examining the condition of the child's limbs, whether there are any abnormalities in unrelated conditions, whether the fetus is generally healthy, and whether the amniotic fluid is normal.
2. Down syndrome screening. Down syndrome screening is conducted by extracting the mother's blood for analysis and testing, often between 15 and 20 weeks of pregnancy. It mainly screens for the presence of Down syndrome in the child. If there are dangerous results in the initial screening, amniocentesis or non-invasive DNA testing is also required for further screening.
