In general, the report of Down’s syndrome screening can show high risk, critical risk or low risk, low risk means good screening result and low risk of fetal disease. high risk is indicated by high beta-HCG corrected MOM value, non-invasive DNA or amniocentesis is recommended for further diagnosis. During pregnancy, you need to complete relevant examinations regularly, especially the screening examinations, such as ultrasound examination in the middle 18-24 weeks of pregnancy, which can systematically examine all the organs of the fetus and can clarify whether there are obvious malformations in the fetus, and according to the examination results, you can also determine the growth and development of the fetus, and if there is any abnormality, you can take timely treatment measures under the guidance of the doctor.
