What does "low-risk non-invasive dna report" mean?

Non-invasive DNA examination is only an abnormal examination and cannot replace chromosome puncture examination. This is more expensive and the specificity is not very good. Under normal circumstances, the results of non-invasive DNA examination are about 1 week.

Introduction: There are many methods to detect chromosomal abnormalities in developing fetus, including non-invasive prenatal DNA detection, also known as non-invasive prenatal DNA detection, non-invasive fetal chromosomal aneuploidy detection and so on. According to the Committee of American College of Obstetricians and Gynecologists [1], an international authoritative academic organization, non-invasive prenatal DNA testing is the most widely used technical name.

Non-invasive DNA prenatal detection technology only needs to take venous blood of pregnant women. The new generation DNA sequencing technology is used to sequence the free DNA fragments (including fetal free DNA) in maternal peripheral plasma. The biological information analysis of the sequencing results can get the genetic information of the fetus, so as to detect whether the fetus has 2 1 trisomy syndrome (Down syndrome), 18 trisomy syndrome (Edwards syndrome) and 65438 trisomy syndrome.
