Paternity DNA testing is a reliable way to determine the true paternal identity of a child, and generally provides 99.9% accurate results. Paternal DNA testing is legally binding and can be used to solve legal issues surrounding the true birth parents of a child, such as alimony, visitation, etc.

The DNA profile of a person possesses two genetic types, also known as alleles, inherited from each parent. By comparing the DNA profiles of the mother and the child, the genetic type inherited form its mother is identified, which leaves the other half being inherited from the childs biological father. The profile of the child and the father is then examined to determine whether the DNA profile matches the paternal alleles in the child.

Although paternity DNA testing is quite accurate, it is never possible to prove 100% that a man is definitely the biological father of a child, as it might be remotely possible that another man may have the same DNA profiling as that of the child. Most paternity DNA testing requires utmost security and confidentiality. One should also ensure that all the specimens collected for analysis should be collected according to the regulations, which require photo identification of all people providing blood samples, specifications for labeling and sealing of sample containers, and maintaining confidentiality of the case details, including names, addresses and results. One should also ensure that the DNA testing centers store all samples and case files in a secure area with tightly controlled access.

The results for the DNA tests are usually issued within five working days of receipt of all specimens by mail to the mother and the alleged father or the legal representative. Although most DNA paternity tests are admissible in most courts of law, it is recommended that you check your state and local governments for regulations that may govern this service.
