DNA Paternity Testing is one of the latest breakthroughs in science and technology. It is has been helpful in several situations such as resolving family issues and assisting in law enforcement matters. In contrast to in the olden days, DNA Testing is actually more readily available and reasonably priced.
There are various methods in administering Paternity DNA Test yet the widely used techniques these days are Polymer Chain Reaction Method (PCR) and Restriction Fragment Length Polymorphism (RFLP). The PCR Method is utilizing polymer – a large molecule made up of repeating structural units. In this method, DNA is removed, fragmented, amplified and then divided by the process of gel electrophoresis. The sequence of the DNA fragments will be studied and compared.
At the same time, Restriction Fragment Length Polymorphism (RFLP) makes use of the homologous DNA sequences. In such type of DNA Test, the taken out DNA is fragmented by enzymes. The DNA fragments are then categorized by size and then undertake identification.
In both methods, DNA samples from the father and the mother is compared with the offspring’s DNA. DNA Paternity Test can carry on even without having DNA samples from the mother yet it will take a bit more of laboratory work. Every single band of the offspring’s DNA must 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 obtained through the Chorionic Villi Sampling (CVS) procedure or the Amniocentesis Procedure. In the 1st procedure, placenta cells are gathered while in the 2nd procedure, fetal cells from the amniotic fluid are collected. Both of these testing methods are obtrusive procedures and may have specific amount of risk hence it should not be carried out with no advice of an OB-Gyne.
Having said that, ethical and health concerns surround prenatal paternity testing with the possible risks to the fetus. It’s consequently encouraged that DNA Paternity Testing be done right after the child is born. It’s safer and a lot more affordable that way. It can be carried out simply by taking blood sample in the umbilical cord.
For Home DNA Paternity Test, huge difference is that samples are accumulated in your house. Procedure resembles a traditional DNA paternity test and is equally precise. For this technique, the samples are sent in to a testing company laboratory. People usually utilize this process for personal purposes only like mere curiosity and to reconcile their doubts. Be reminded that in this type of procedure, the actual result is not admissible in court. So if you are planning to provide the result in court, home DNA paternity testing isn’t the proper method.
