So, compared with traditional Down's screening, what are the advantages and significance of non-invasive prenatal DNA testing? As a new type of obstetric examination, non-invasive prenatal DNA testing is an examination method for Down's screening at present, which can achieve an accuracy rate of over 99% in the early pregnancy and will not cause trauma to women. Experts pointed out that the difference between this inspection method and other inspection methods lies in its non-invasive, safe and accurate characteristics. Pregnant women only need to extract about 5 ml of venous blood from the body to sequence the fetal DNA fragments contained in the blood through relevant instruments, and this kind of examination will have relevant oral answers within two weeks, and there will be a complete test report in the third week of the examination. If the test result at this time is low risk, then the pregnant woman can continue her pregnancy and wait for delivery after the completion of the pregnancy stage. If the test result is high risk, corresponding measures can be taken at the first time, including induced labor operation, to avoid serious harm to women's health. Shenyang Meideyin Women and Children Hospital has strong obstetric technical strength and advanced and reliable medical equipment, which provides the most solid guarantee for the safe production of pregnant women. Obstetrics has an international standard laminar flow operating room, equipped with a full set of fetal monitoring system, which can provide a good guarantee for prenatal and perinatal fetal monitoring.
