DNA testing is a relatively new technology, but the many benefits of DNA testing have caused the use of these methods to virtually explode in a wide variety of applications. Some of the most well-known benefits of DNA testing have been seen in the arena of criminal justice. The guilty are found and convicted and the innocent are exonerated, all on the basis of microscopic evidence that nevertheless is more unique than a fingerprint. DNA fingerprinting or profiling provides a way to identify people and their relationships beyond a shadow of doubt. In many ways, it’s the certainty of the DNA test results that provide the major benefits of DNA testing.
One of the primary benefits of DNA testing outside of the criminal justice field is to assist women who are seeking financial support for their children. In cases where a man denies that he is the biological father, DNA paternity testing can confirm or exclude a biological relationship and allow the courts to determine whether or not he is legally responsible for child support payments.
Men who are seeking custody or visitation rights may avail themselves of the benefits of DNA testing. Again, a DNA paternity test provides a crucial confirmation of the existence of a biological relationship between father and child. This confirmation is necessary before awarding custody or visitation rights.
Some men merely need to gain peace of mind regarding their relationship to a child. One of the benefits of DNA testing is being able to conclusively establish or exclude a relationship.
Adopted children may someday wish to find their biological parents. DNA testing will allow them to confirm the biological relationship between themselves and their possible biological heritage.
Other benefits of DNA testing include the ability to establish grandparentage and to inform decisions on inheritance rights, insurance claims or Social Security benefits. U.S. immigration officials have begun accessing the benefits of DNA testing for proving various biological relationship in foreign immigration cases.
Some of the less well-known benefits of DNA testing lie in the study of genealogy. Individuals may be interested in their ethnic origins or their ancestry. DNA testing provides clues they can pursue in search of their personal beginnings. Individuals can find if someone that shares their surname also has a biological relationship.
New benefits of DNA testing include screening for genetic markers of future illness like cancer and Alzheimers Disease. The benefits of DNA testing have already begun to expand even beyond human use. Pet owners have embraced DNA testing for use in health care, breeding, and identification.
