DNA Testing - The Most Common Uses of DNA Tests

The Most Common Uses of DNA Tests

Advances in DNA technology have resulted in the increased use of DNA tests. From paternity tests to criminal investigations, the accuracy and data provided mean that millions of people are now turning to DNA testing to answer their questions.

Below are the seven most common uses for DNA testing:

1.    Archeologists are now using DNA tests to keep a record of genetic codes and progression of life on earth dating back centuries. This has resulted in a DNA database, which can be used for reference and comparison purposes. By profiling the DNA of living organisms, scientists have proved evolution and genetic mutation, answering questions on the origins of species.

2.    A paternity test is the most definitive way of confirming a child’s paternity. Whether for peace of mind or for legal issues, the question of a child’s paternity has never been more important, leading to new legislation in support of the child’s right to know. There is also a growing number of sibling and grandparent tests, which can also form part of a legal case or fill gaps in a family’s history. Contact us for paternity test services.

3.    With an interest in family trees growing, a DNA test can also be used as part of a search for your genetic ancestors. Since the Y chromosome found in males is likely to remain unchanged from generation to generation, its analysis can be used to set up ancestral lines. Many people are now using DNA tests to establish the ethnic origins of their DNA and ancestors which can be dated back hundreds of years.

4.    Through the use of prenatal genetic tests, doctors can now assess whether or not the unborn fetus will have health problems. Doctors can also use DNA testing to assess the probability of risk of certain genetic diseases, for example prostate cancer can now be identified as a high risk, ensuring regular checkups, which will lead to possible identifying the cancer in its early stages.

5.    DNA tests are now being widely used in criminal investigations. In cases with repeat offenders, police are able to store DNA profiles and compare them with the samples of other unsolved crimes. Recently, there have been cases in the news of individuals, previously convicted of crimes, being released following new evidence submitted through DNA testing. Many cases, previously labeled unsolved, have also been dealt with through new ways of analyzing evidence.

6.    Many people tracking down long lost relatives are also using DNA tests. By analyzing a person's DNA, matches can be established, and families reunited and relationships renewed. Especially in cases where members of the family are deceased, through sibling and grandparent tests, biological relationships can now be confirmed.

7.    In the spectrum of space research, scientists are also conducting DNA tests on new species and unidentified articles from outer space. This can be a vital link in establishing origins and connections to existing life forms.

As DNA technology evolves, so will advances in its use of testing. The accessibility and widespread use mean that testing is also becoming cheaper. Its many uses in criminal, civil and personal cases mean that many of today’s questions can be answered with a simple test.
