Paternity-DNA Test

A paternity-DNA test is performed to discover whether an individual is the biological father of a particular child or not. The process requires a small sample of bodily fluids or tissue extracted from both the boy and the potential father. It is also considered as the genetic fingerprint that forms our chromosomes and genes. Moreover, did you know that half the DNA of your mother and father is what contributed to your DNA? A paternity test can determine the biological relationship between the baby and the father – which also make it important that you have it performed in DNA testing in NYC.

Paternity-DNA test performance

Performing a paternity test is technically easy. The cells in our body contain most of our DNA and a testing sample can be taken from multiple bodily sources. A DNA test is commonly performed through buccal cells – which are present inside the cheek of your mouth. To conduct the cheek cell test, the sample is collected by rubbing a cotton swab inside the cheek of the father’s mouth. The sample later goes to a laboratory for further examining. After the examination of a number of particular DNA series, it is identified whether the DNA samples of the baby and the father match or not.

Also, the paternity can be performed through two methods before the birth of the baby i.e.

1. Invasive paternity testing
2. Non-invasive paternity testing

Invasive paternity testing

In invasive paternity testing, the DNA test can be performed through two methods – chorionic villus sampling and amniocentesis. However, it is important for you to select the best DNA testing center in NYC.

The chorionic villus sampling (CVS) is performed between 11 and 13 weeks of pregnancy only. The procedure of the test includes examining a tiny tissue sample taken from the placenta.
The amniocentesis is usually conducted in 16 and 22 weeks during pregnancy. In the process, a needle passes through the abdomen of the mother to collect a sample of amniotic fluid, which is basically the water around the baby, which also what contains its cell.

These paternity tests are accurate and recommended because the samples are directly taken from the fetus. Apart from this, there is a small risk of miscarriage associated with both testing processes that is one percent CVS and 0.5% for amniocentesis. Therefore, it is suggested to consult only a genetic specialist (maternal-fetal medicine specialist) for the performance of these procedures.

Non-invasive paternity testing

The advancement in genetic testing has allowed experts to discover the biological father of the baby before the child is born. In non-invasive paternity method, a tiny amount of fetal DNA (cffDNA) is taken, which is available in the woman’s blood during pregnancy. The results of this procedure are accurate and there is not any risk of miscarriage associated with it. According to several studies, cffDNA can be performed only in seven weeks of gestation. It is noteworthy here that the amount of cffDNA increases as pregnancy proceeds.

Apart from this, DNA tests are also essential for legal requirements i.e. child support, inheritance, social welfare benefits or adoption process. And to get accurate DNA test results, contact us now and book an appointment with the most trusted DNA testing center in New York City.
