DNA testing is by far the most effective and accurate means by which a biological relationship can be said to exist between one person and another. Whether that be through traditional paternity testing or alternatively testing some more distant relationship (usually in order to determine paternity), such as avuncular testing or grandparentage testing, there are a number of significant reasons for using DNA testing where disputes or potential discrepancies arise. Whilst there is a minimal margin for error in any testing, DNA testing is the most accurate form of establishing relationships available, which makes it ideal for use in a number of scenarios.
Legal Use One of the most common uses for DNA testing is for legal reasons. There are a number of legal scenarios where paternity, or family relationships become important to the outcome of a case. Whether that be an intestate inheritance dispute, where determining family relationships could have a significant bearing on the execution of a particular estate, or some child law reason, DNA testing is one of the most accurate ways of picking up on genetic relationships which can provide the necessary proof for determining the correct legal outcome. As a result of its increased effectiveness over other methods of detection, nothing compares to DNA testing for accurately determining family relations.
Medical Use Medical use is the other major field of practice for DNA testing. In medical situations, it can often be important to determine biological relationships in determining potential exposure to certain genetic conditions and in matching suitability for certain treatments. As medical research continues to advance, so too DNA testing becomes more high profile and more widely used in general practice as a far more conclusive way of identifying family relationships where is matters most.
"Curiosity" Testing Whilst testing doesn't usually require maternal DNA samples, the at-home, or so-called Curiosity test is a good way to get peace of mind or to determine with some conclusivity whether or not you share a family relationship with another person - mostly a child. By testing oral swabs through a DNA testing kit normally sent to the client, the at-home testing is both easy to effect and accurate in producing results for determining DNA links where paternity is in question. For personal reasons or just for the sheer curiosity, the at-home test is far less controlled by protocol, but nevertheless can come up with accurate results where a particular relationship exists.
DNA testing is becoming more and more available, as the most accurate means of testing relationships. Where there is at least some degree of relationship, there is nothing more effective at determining genetic relationships than DNA testing, particularly in light of the advances in testing technology in recent years. From paternity testing through to siblingship testing and even grandparentage testing, using a DNA test can be a cost-effective and accurate way to determine whether or not alleged relationships do in fact exist. With that in mind, DNA testing should be your first choice of action should a family disputes arise on a biological relationship.
