When will the non-invasive DNA results be available?

Prenatal check-up items include non-invasive DNA, Down syndrome screening, amniocentesis, etc. Through these tests, it is possible to find out whether the fetus has congenital diseases or chromosomal diseases. For example, non-invasive DNA is mainly used to check for sex chromosome diseases. Non-invasive DNA can be tested from more than 12 weeks of pregnancy. So how long does it take for non-invasive DNA to produce results?

How long does it take for non-invasive DNA results to come out?

Non-invasive DNA testing is safer by collecting 5-10mL of peripheral blood from pregnant women to obtain DNA from mineral acids. Compared with the traditional amniocentesis test, there is no need to insert relevant equipment deep into the pregnant woman's body for sampling, allowing pregnant women to undergo the examination at ease. Since 2012, non-invasive DNA testing has been able to accurately detect the three major sex chromosome diseases: Down syndrome (T21), Maria syndrome (T18), and Parkinson syndrome (T13). The non-traumatic nature of non-invasive DNA prenatal testing can avoid the risks of miscarriage and infection caused by invasive diagnosis. The perfect features of DNA sequencing technology ensure the accuracy of the technology. Pregnant women over 12 weeks can be tested and the test results can be obtained within 10 working days. So, relative to sheep piercing. Non-invasive DNA is a more suitable option for mothers, but nowadays, it is not necessarily available in all hospitals.

How is non-invasive DNA testing performed?

Non-invasive prenatal DNA testing is also known as minimally invasive prenatal DNA testing, minimally invasive fetal sex chromosome aneuploidy testing, etc. According to the American Association of Colleges of Obstetricians and Gynaecologists, an international authoritative academic research organization, minimally invasive prenatal testing (Non-invasive Prenatal Testing) is the name of the most widely used technology. The non-invasive DNA prenatal non-destructive testing technology only uses the pregnant woman's venous blood, and uses the new generation of DNA sequencing technology to sequence the mineral DNA fragments (including the fetal mineral DNA) in the pregnant woman's jugular vein blood. The sequencing results are then analyzed for biological characteristics, from which the fetus's genetic material can be obtained, thereby testing whether the fetus suffers from the three major sex chromosome diseases.
