Non-invasive DNA high-risk requires an amniotic fluid puncture and umbilical cord blood puncture, and then determine whether to terminate the pregnancy based on the situation. Non-invasive DNA high-risk does not necessarily indicate that the fetus has a serious problem that requires termination of pregnancy. Amniotic fluid puncture and umbilical cord blood puncture have high diagnostic accuracy and can be used as a basis for subsequent treatment. What should I do if the non-invasive DNA is high-risk? If the non-invasive DNA test for pregnant women is high-risk, they need to follow the guidance and conduct a review before delivery. Non-invasive DNA is not a prenatal diagnosis and will not directly use it as a basis for termination of pregnancy. Currently, the examinations used to terminate pregnancy are amniotic fluid puncture and umbilical cord blood puncture. The accuracy of these two examinations is very high, reaching 99%. When the non-invasive DNA test is high-risk, amniotic fluid puncture is required. This examination can diagnose whether the fetus has chromosomal abnormalities, neural tube defects, and other genetic metabolic diseases. Therefore, if non-invasive DNA high-risk is detected, it cannot be used as the final diagnostic criterion, and amniotic fluid puncture is still required. The purpose of amniotic fluid puncture:
1. To check whether the fetus is in distress. During the production process, due to prolonged labor, hypoxia, or compression, the fetus may experience distress. If it can be detected in time, relevant measures can be taken promptly to avoid serious consequences.
2. To identify the gender of the fetus. Amniotic fluid puncture can check the gender of the fetus. Judging the gender of the fetus through chromosomes and endocrine substances contained in amniotic fluid is a simple and accurate method of identifying the gender of the fetus.
3. To check whether the fetus is deformed. Through amniotic fluid puncture, the fetus can be detected for chromosomal abnormalities, neural tube defects, and the risk of certain genetic metabolic diseases that can be reflected in amniotic fluid.
4. To check the growth and development of the fetus. To determine the expected date of delivery and gain a detailed understanding of the fetus's growth and development, amniotic fluid can be extracted at an appropriate time for analysis to determine the degree of fetal maturity.
