Non-invasive PLUS can examine in detail many chromosomal and genetic disorders such as 21-trisomy, 18-trisomy, Turner syndrome, genetic variants, etc. Non-invasiveplus is a further improvement and supplement to non-invasive DNA testing. By extracting fetal DNA fragments from maternal peripheral blood, it can analyze the chromosome type of the fetus and clarify the presence of 21-trisomy, 18-trisomy, 13-trisomy, Turner’s Syndrome, Kirschner’s Syndrome, Hyper-Androgenation, and Hyper-Feminine Syndrome in the fetus. Noninvasiveplus can also analyze the genetic sequence of the fetus, which can clarify whether the fetus has gene deletions, microduplications, mutations, and other related gene mutation-type disorders. It is important to note that the accuracy of the non-invasive plus test is not 100%, pregnant women should standardize the obstetric examination under the guidance of a professional physician to avoid adverse pregnancy outcomes.
