Paternity test during pregnancy: how it's performed, and what features

Already this fall on TV STB will premiere the project, which has no analogues on Ukrainian television - "Taєmnitsі DNA."

As part of the talk-show heroes learn the secrets of their DNA, and get answers to vital questions. Sometimes a genetic examination can put everything in its place. How to do a DNA test during pregnancy and in what period it is possible to carry out - said the expert of the project, geneticist Elena Piedmont.

Today, DNA paternity test can be carried out even during pregnancy. Genetics According to that used the two most common methods - invasive and non-invasive. Holding each of them is important for different gestational age. In addition, prior to the decision to test the delivery should always consult with a physician.

"Invasive techniques performed from 11 weeks of gestation. Such a fence material implies intervention in the natural environment to the fetus fence material for further studies. Depending on the duration of pregnancy to determine the paternity of chorionic villi can be used, umbilical cord blood or amniotic fluid - all these materials contain fetal DNA required for comparison.

The second method - non-invasive DNA test for paternity (INTI) - held from the 10th week of pregnancy. Establishing paternity in this case is made by identifying the fetus in the future mother's blood (his mother would take blood from a vein). If the male embryo, it comprises a Y-chromosome, which greatly facilitates the process.

If the unborn child female, determine paternity will allow analysis of both X-chromosome for matches. accuracy studies DNA is 99.9%, that in the absence of contraindications and risks making the ideal method to determine paternity during pregnancy "- explains the expert.
