What are the different methods of testing fetal paternity?

In order to determine who the father of her child is before the child's birth, the expectant mother may decide to test the fetal paternity. The establishment of paternity before giving birth can be done using three methods. Two invasive methods that can be performed simultaneously as other tests include fluid extraction from placenta or amniotic bag. If for some reason the mother does not want to have or cannot do these procedures, it may decide to perform a more non -invasive fetal testing. This test is usually performed for 10 weeks up to pregnancy up to 14 weeks to pregnancy. Using this method, chorionic villi cells that contain fetal DNA are extracted from the placenta. DNA is then compared with a father to establish paternity. The results of this test are considered almost 100 % accurate.

There are two methods that can be extracted by these cells. In the transcherical procedure, there is a very thin catheter led through the cervix with ultrasound. The cells are then sucked and collected. During TransabdomUltrasound is also used in the procedure, but instead of walking through the cervix, the cells are collected by passing the mother's abdomen. Using a thin needle, the obstetrician leads the needle to the placenta and extracts a small amount of these cells.

Using obstetricians using a procedure known as amniocentesis, obstetricians can also test the fetal of paternity. This procedure is usually performed between 14 and 24 weeks to pregnancy and involves collecting the sample of the fetal fruits. Like CVS Fetal Fetal Testing, the collected DNA is compared with a father and this test is considered very accurate.

During this procedure, the obstetrician Ultrasound uses a safe place to stick the needle into the mother's abdomen. After placing a safe entry point, a long thin needle is inserted into the mother's abdomen after the local anesthetic is served to dull the area. When an amniotic bag is pierced, a fetal te sample is takenKutiny. This fluid contains fetal cells. These cells are isolated from fluid and used in prenatal paternity testing.

Recent research has determined that some of the bottom of the unborn child into mothers in the mother's blood heath through the placenta. A relatively new procedure called testing of fetal paternity of fetal cells/DNA has been developed, which can usually be performed at any time after 14 weeks. During this prenatal paternity test, the mother's sample is taken and the bottom of her child is isolated. It is then compared with the DNA of the father. Although this procedure is slightly cheaper and considered non -invasive, it is not considered accurate and many test results are not allowed as evidence of court.
