Women need to undergo a lot of obstetric examinations after pregnancy, especially screening for congenital genetic diseases, which is of great significance for timely detection of fetal abnormalities. Non invasive DNA testing is one of the important tests. So, is non-invasive 13 body high-risk accurate?
The accuracy of non-invasive DNA testing is relatively high, generally reaching over 90%. The detection rate of chromosomal diseases in non-invasive 13 body syndrome is not less than 90%. However, the results obtained from non-invasive DNA testing show that it is not the final diagnosis, and timely follow-up is necessary because there may be a possibility of missed detection.
If a pregnant woman with a high-risk screening result appears, it is not advisable to terminate the pregnancy immediately, but rather to undergo some interventional prenatal diagnosis based on her own condition. For example, timely diagnosis of whether the fetus has some genetic chromosomal diseases can be done through examination items such as chorionic villi biopsy, basal blood puncture, amniocentesis, etc.
Non invasive DNA testing is a non-invasive examination method, which can greatly avoid the occurrence of intrauterine infections during prenatal examinations. If the non-invasive DNA test result is positive, it is necessary to make a clear diagnosis through amniocentesis, and the time for non-invasive DNA testing should be around 16 to 21 weeks of pregnancy.
