The results of non-invasive DNA report card usually come out in about 1 week. For pregnant women with high-risk results, the hospitals will be notified by the staff to call for recall; for pregnant women with low-risk results, some hospitals will send out SMS notification; in some areas, the results can be accessed through the relevant websites, and local hospitals should be consulted for details. Non-invasive DNA is to check for three kinds of chromosomal disorders, including trisomy 21-trisomy, trisomy 18-trisomy and trisomy 13-trisomy, which are mainly manifested as intellectual disabilities and growth and developmental abnormalities, with a detection accuracy rate of more than 99%. Especially for pregnant women with high risk of Down’s syndrome, this test is a must, which is not harmful to the fetus and the pregnant woman herself, and it is enough to draw 5ml of vein blood from the pregnant woman. Pregnant women with high risk results need to undergo further amniocentesis, and if they are still at high risk, labor should be induced promptly. Therefore, pregnant women undergoing non-invasive DNA testing should not worry too much during the waiting period, and should maintain a happy mood, have sufficient rest, eat a reasonable diet, and do not be overly anxious, so as not to affect the development of the fetus.
