DNA Paternity Testing And The Steps Necessary

DNA Paternity Testing is among the most current advancements in science and technology.  It continues to be beneficial in numerous situations just like resolving family issues and helping in law enforcement matters.  Contrary to in the years ago, DNA Testing is now more accessible and inexpensive.

There are various methods in administering Paternity Test but the well known methods in these modern times are Polymer Chain Reaction Method (PCR) and Restriction Fragment Length Polymorphism (RFLP).  The PCR Method is using polymer – a large molecule made up of repeating structural units.  In this procedure, DNA is taken out, fragmented, amplified and then divided by the process of gel electrophoresis.  The sequence of the DNA fragments will be studied and in comparison.

In the mean time, Restriction Fragment Length Polymorphism (RFLP) makes use of the homologous DNA sequences.  In this kind of DNA Test, the extracted DNA is fragmented by enzymes.  The DNA fragments are then sorted by size and then undergo identification.

In each methods, DNA samples from the parents is in comparison with the offspring’s DNA.  DNA Paternity Test can continue even with no DNA samples from the mother however 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 obtained from the Chorionic Villi Sampling (CVS) procedure or the Amniocentesis Procedure.  In the initial procedure, placenta cells are accumulated while in the next procedure, fetal cells from the amniotic fluid are accumulated.  Each of these testing methods are invasive methods and may even have specific amount of risk thus it shouldn’t be performed without the advice of an OB-Gyne.

On the other hand, ethical and medical issues surround prenatal paternity testing as a result of possible risks to the fetus.  It’s consequently recommended that DNA Paternity Testing be achieved right after the child is born.  It’s safer and much less costly that way.  It can be achieved simply by taking blood sample from the umbilical cord.

For Home DNA Paternity Test, the enormous difference is the fact 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 often take advantage of this process of personal purposes only like mere intense curiosity and to settle their doubts.  Be reminded that in this type of procedure, the result is not admissible in court.  Therefore if you are intending to present the result in court, home DNA paternity testing isn’t the best suited method.
