DNA test father evidence can be used to determine conclusively whether or not a certain individual is the father of a child. In the past, it was possible to assess the probability of someone being the father of a child, but it could never be conclusively proven. Even the probabilities could be hard to assess when every party involved was of the same common blood group. Often, who the father was likely to be was simply decided on appearances, on who was believed to be in the right place at the right time, and other factors which gave no hard evidence.
The science of DNA testing is very young, having only been discovered and developed during the 1980s. There have been continuous advancement since that time, and also several problematic errors which have cast doubt upon certain aspects of the system. Paternal DNA testing has always been one of the most robust and reliable applications of the technology, because samples can be taken from living beings, and analyzed in real time within minutes of them being taken.
DNA testing operates by analyzing certain strands of DNA which are inherited from both parents. These strands are unique to the individual, and are the reason why DNA testing ancestry procedures are among the most accurate. It is in criminal cases where the samples may have degraded, or where there is doubt as to how they were initially obtained, where the gray areas occur. Provided the tests are carried out properly and with due care and attention, there is no reason why a family DNA test should not be completely accurate.
There have been very rare instances of problems even with family tests, where people have been found to have two separate DNA identities. In two celebrated cases, someone who was definitely the mother of her children was “proven” not to be by DNA analysis. It was found that a different DNA sample taken from the same body would have produced the correct result. It has to be admitted that these cases are exceptionally rare and that a DNA paternity test would have an outstanding accuracy rate.
Once a DNA test father has been identified, they can then rightfully take their place of responsibility for the child. Because DNA evidence is so accurate when it is obtained and used in the right way, it also has the benefit of satisfying the doubts of close relations and friends of the family. Where a conclusion has been reached in this way, there is far less likely to be any doubt cast over it. This can lead to far more harmonious and trouble free lives for everyone involved. Even those who were wanting a different result will usually accept that the real father is the DNA test father.
