DNA Paternity Testing has become the recent discoveries in science and technology. It has been helpful in many situations just like fixing family issues and assisting in law enforcement matters. Not like in the olden days, DNA Testing is now more accessible and affordable.
There are various methods in giving Paternity Test however the well known methods these days are Polymer Chain Reaction Method (PCR) and Restriction Fragment Length Polymorphism (RFLP). The PCR Method is making use of polymer – a large molecule consists of repeating structural units. In this process, DNA is extracted, fragmented, amplified and then divided by the process of gel electrophoresis. The sequence of the DNA fragments will be studied and in comparison.
At the same time, Restriction Fragment Length Polymorphism (RFLP) makes use of the homologous DNA sequences. In this particular DNA Test, the extracted DNA is fragmented by enzymes. The DNA fragments are then sorted by size after which go through identification.
In the two methods, DNA samples from the father and the mother is in contrast to the offspring’s DNA. DNA Paternity Test can continue even without DNA samples from the mother yet it will take more of laboratory work. Every band of the offspring’s DNA have to match a band with the father to conclude that she or he indeed his child.
In Prenatal Paternity Testing, samples of the unborn baby’s DNA are acquired from the Chorionic Villi Sampling (CVS) procedure or the Amniocentesis Procedure. In the primary procedure, placenta cells are collected while in the next procedure, fetal cells from the amniotic fluid are collected. Each of these testing methods are invasive procedures and could have certain quantity of risk thus it shouldn’t be carried out with no advice of an OB-Gyne.
Nevertheless, ethical and medical concerns surround prenatal paternity testing as a result of possible risks to the fetus. It is therefore suggested that DNA Paternity Testing be performed soon after the child comes into the world. It’s safer and way less costly that way. It can be carried out by just taking blood sample from the umbilical cord.
For Home DNA Paternity Test, the big difference is always that samples are collected in your house. Procedure is similar to a traditional DNA paternity test and are just as accurate. For this process, the samples are sent in to a testing company laboratory. People today almost always take advantage of this technique of personal purposes only like mere curiosity and to settle their doubts. Be reminded that in this type of procedure, the result is not admissible in court. Thereby in case you are planning to present the result in court, home DNA paternity testing isn’t the most appropriate method.
