Performing a DNA paternity test is the one way to find out for sure if a man is the true biological father of a child. In cases where there is any doubt as to the identity of a child's father, such as where a mother's fidelity is in question, or in some legal child support or custody cases, a paternity test can provide unequivocal results. DNA testing is the most accurate and reliable method of determining the truth about a paternal relationship, with the results providing the conclusive proof that is needed.

Home paternity tests are inexpensive to buy and are easy to use. A paternity test kit will come complete with all the equipment that is needed, such as swabs, forms and containers. Most home DNA tests require the use of buccal swabs to take DNA samples from the inside cheeks of all parties involved. The alleged father and child obviously need to be tested, but it is useful to test the mother as well if possible. The samples need to be placed carefully into labeled tubes or containers and returned to the laboratory for analysis. Most companies that offer paternity test services aim to mail the results back to you as quickly as possible, which can take around a week in most cases.

DNA paternity testing involves the comparison of the DNA sequences for man, child and in many cases the mother. We each have 23 pairs of chromosomes, half of which we inherit from our mother, the other half from our father. If a match is found between a child's DNA and the man's, there is no doubt that he is the biological father. Having a sample of the mother's DNA can help by removing her DNA from the equation.

If there are doubts or disputes about a paternal relationship, then taking a paternity test is the way to know for certain if a man is the biological father of a child. DNA testing is a straightforward procedure that can be done in the privacy of your own home, and provide you with the answers you need.
