What should I do about the critical risk of Tang Sie? Is it serious?

Tang screening is a prenatal screening method used to detect fetal chromosomal abnormalities and is widely used in clinical practice. The purpose of Tang screening is to evaluate whether the fetus has chromosomal abnormalities, such as Down syndrome, through the measurement of free DNA in the blood. However, there are critical risks in Tang screening results, which brings a certain amount of trouble and pressure to pregnant women and doctors. First, we need to understand the principle of Tang sieve. Tang Screen evaluates whether there are chromosomal abnormalities in the fetus by measuring the content of cell-free DNA in the blood of pregnant women. Cell-free DNA is a type of DNA released by fetal cells in maternal blood, and its content is related to the risk of fetal chromosomal abnormalities. Based on the Tang screening results, doctors can further evaluate whether the fetus has chromosomal abnormalities and recommend that pregnant women undergo further examinations, such as amniocentesis or chorionic villus biopsy. However, the Tang screening results are not absolutely accurate. The critical risk of Tang screening refers to the results within a certain threshold range. At this time, it cannot be determined whether the fetus actually has a chromosomal abnormality. Borderline risk means there is a certain amount of uncertainty, which creates problems for pregnant women and doctors. Pregnant women may worry about the health of their fetuses, while doctors face issues of interpreting borderline risk results and communicating them to pregnant women. In view of the critical risks of Tangsie, a comprehensive assessment needs to be carried out first. Doctors will combine the maternal age, gestational age, Tang screening results and other factors to comprehensively determine whether the fetus is at risk of chromosomal abnormalities. In addition, doctors will consider other test results, such as ultrasound, to get a more comprehensive picture. A comprehensive evaluation can help doctors more accurately determine whether the fetus has chromosomal abnormalities. Secondly, pregnant women need psychological counseling and support. A critical risk test result can cause anxiety and stress to pregnant women, so psychological counseling and support are very important. Doctors can explain to pregnant women what borderline risk means and help them understand the uncertainty of the results. In addition, doctors can provide information about other prenatal tests to help pregnant women make more informed decisions. Finally, borderline risk for Tang screening does not necessarily mean there is a chromosomal abnormality. Pregnant women and doctors need to remain calm and rational when faced with borderline-risk outcomes. If a pregnant woman decides to undergo further testing, such as amniocentesis or chorionic villus biopsy, the doctor will develop a plan based on the specific situation. These further tests can provide more accurate information to help pregnant women and doctors make clear decisions. In summary, although there is some uncertainty in the critical risk of Tang screening, it does not mean that there must be a chromosomal abnormality. Doctors need to conduct a comprehensive assessment, and pregnant women need psychological counseling and support. When faced with borderline risk outcomes, pregnant women and doctors need to remain calm and rational and make appropriate decisions based on the specific circumstances. The ultimate goal is to protect the health of the fetus and pregnant woman.
