The high risk of non-invasive DNA is important and suggests that the baby is at a higher risk of chromosomal trisomy. Non-invasive DNA testing involves taking a pregnant woman’s venous blood, from which genetic information about the fetus can be obtained to test for the three major chromosomal disorders: trisomy 21, trisomy 18, and trisomy 13. The success rate of non-invasive DNA can exceed about 96%, but it is not 100% accurate. A high risk of non-invasive DNA suggests that the baby is more likely to have chromosomal trisomy, and amniocentesis is required to confirm the diagnosis. Amniocentesis is nearly 100% accurate. If you have a high risk of non-invasive dna, you should go to a qualified hospital as soon as possible for further examination, and take appropriate treatment according to the results of the examination.
