What is the non-invasive DNA test for pregnant women?

There are actually a lot of tests that pregnant women need to do, and each one is very important. Of course, there are also many tests that can be omitted. Most pregnant women are not familiar with these tests and do not know what they actually check. Most pregnant women don’t know about non-invasive DNA testing, so what does non-invasive DNA testing for pregnant women check?

Non-invasive DNA is a very good test during prenatal examinations. If it is the first pregnancy, the pregnant woman may not be familiar with this test. In fact, non-invasive DNA and Down syndrome screening are similar, but it has a wider range than Down syndrome screening. It can check whether the fetus suffers from Tang Shi Song Ci syndrome, Maria syndrome, and other chromosomal diseases.

During the period of Down syndrome screening for pregnant women, high-risk conditions may occur. Minimally invasive DNA testing is actually more accurate. During the test, blood will be drawn for testing, which requires about five millimeters of blood from the pregnant woman, and then it is determined whether there are any abnormalities in the fetus's sex chromosomes. The test results are actually very accurate, and it is a very important test during pregnancy.

In early pregnancy, Down syndrome screening is needed, around 11 weeks after pregnancy. Minimally invasive DNA testing is suitable for testing at 22 weeks and 6 days of pregnancy. It is very important for pregnant women to have all the examinations during pregnancy. You can consult a doctor in advance and understand the purpose of each examination so that the fetus can grow and develop healthily.

When a pregnant woman undergoes a minimally invasive blood test for DNA, it is used to test whether the fetus has symptoms of trisomy 21 Down syndrome, trisomy 18 Maria syndrome, and trisomy 13 Patau syndrome. Minimally invasive DHA is a new generation of DNA testing technology that tests the DNA dispersed in the jugular vein blood of pregnant women, and can determine whether the fetus has any genetic diseases. It has a relatively high safety factor and can be tested at 12-24 weeks of pregnancy, with results available within 10 working days. Most of them are for those who are over 35 years old. There is a higher probability when doing Down syndrome screening. At this time, a minimally invasive DNA follow-up test can be carried out. Its accuracy is much higher than that of Down syndrome screening, with an accuracy of about 90%.
