Although older methods are still used in parental testing, DNA is at the moment the most advanced and accurate way to determine parentage. A father paternity test done in this way will give genetic proof whether a man is the biological father of a baby or not. With DNA testing, proof that the alleged father is not biologically related to the baby will be 0%, and 99.9% will be definite proof that the alleged father is indeed biologically related to the baby.
Many times, when it is suspected that a woman may have had an affair, doubts arise as to the paternity of her child. In order to clarify whether her partner/husband is indeed the biological father of her child, a father paternity test will be carried out. This test is carried out to make sure that the biological father of the child will accept and carry out his responsibilities as a father.
There are standard, cheaper, father paternity tests available, the results of which are for your own private knowledge. However, should the test be required as evidence in a court of law, a laboratory member of the AABB Parentage Testing Accreditation Program has to carry out the actual testing for the procedure to be considered legal.
The reason for this is first of all to ensure that the tests are done properly, that legal channels are followed, and that documentation processes are done properly and are acceptable in a court of law. In other words, proper records of the outcome of the father paternity test are essential, as with any other type of legal situation.
Having a father paternity test has its advantages and its disadvantages as well. If found that the boyfriend/husband is the father of the child, then this will get rid of any suspicions of the woman in the relationship/marriage having an affair. However, it will also cause resentment on the part of the woman, as she will realize, and not like the fact, that her partner/husband did not fully trust her.
Of course this means that because of the father paternity test, regardless of the outcome, the relationship or marriage could suffer adversely, and in many cases, even end. It is for this reason that a father paternity test should initially be carried out privately, the results only being known to you and your husband/partner. In the event of the relationship/marriage ending, a legal paternity test can be carried out.
A father paternity test can and will save a lot of unnecessary conflict, as it will give conclusive proof whether you are the biological father or not. Also, as the DNA of an original egg cell will be in your genes for the rest of your life, a father paternity test can be carried out on anyone, from a fetus to an adult.
