Is the non-invasive venous blood paternity test, which can be done at 6 to 12 weeks of pregnancy, reliable? Baidu to the answer will not have to write down thank you!

Many newly pregnant mothers are consulting the paternity testing center said: non-invasive venous blood identification, just extracting pregnant women's venous blood, extracting maternal blood free fetal DNA, and the suspected father samples to do than. Not invasive way, not touching the fetus, on the pregnant woman and the fetus is the most safe and non-invasive, the same way as the hospital blood test.

Fetal paternity testing methods:

Prenatal paternity testing can be divided into chorionic villus biopsy prenatal paternity testing, non-invasive venous blood and amniocentesis identification depending on the pregnancy and the sample. These three types of identification are consistent with the accuracy of identification after the child is born.

(1) Pregnant women 10-15 weeks pregnant can extract chorionic villi through chorionic villus biopsy to do identification, but not all three hospitals extract chorionic villi.

(2) After 6 weeks of pregnancy, you can do the paternity test through the vein blood of the pregnant woman, the vein blood of the pregnant woman is extracted, and there is no harm to the baby and the pregnant woman.

(3) A pregnant woman can have her amniotic fluid extracted by amniocentesis from the 16th to 30th week of her pregnancy for identification. It needs to be extracted under ultrasound by a professional physician in a regular tertiary hospital.

Non-invasive venous blood fetal identification in the second generation of technology on the basis of the introduction of returnees, the purchase of the most advanced equipment costs more than 30 million, the exclusive domestic research and development of first-class scientific research and technology team, through the DNA amplification of the second generation of high-throughput sequencing, the successful development of a new "third-generation" non-invasive latest identification technology, with the most advanced in the country, the most advanced technology, the most advanced in the third generation of non-invasive identification. The technology is the most advanced and leading level in the country. Based on the high cost, we guarantee you 100% accuracy of the results.

But a lot of people are still curious about why taking blood from a vein can tell you who the father of a child is.

The paternity testing center said: non-invasive paternity testing is through the presence of fetal free DNA in the blood of pregnant women, which provides a technical basis for non-invasive fetal paternity testing. Pregnant women in good physical condition after 6 weeks of pregnancy can try to identify, collect venous blood, at this time the content of fetal free DNA in the blood is more stable. This is followed by DNA amplification, three-generation high-throughput sequencing and data analysis to arrive at a parentage index with the suspected father.
