Understanding Reasons For Legal Paternity Testing

By Ronald Jackson


Currently, DNA testing is all the rage when it comes to seeking information about ancestry and heritage. While this is the case, there are a number of other reasons individuals seek out such tests. In one case, DNA is used in legal paternity testing to confirm the biological connection between father and child.

DNA being used for a number of paternity related issues uses genetic fingerprinting to prove whether or not two individuals share biological markers. The test, which is 99.9% accurate establishes genetic proof using the paternal DNA of the father to prove a biological connection to a child. Whereas, a maternity test can now establish whether a woman is the birth mother.

Paternal DNA tests can also provide information as to the likelihood of grandparents having a biological connection to grandchildren. While new DNA tests are often considered the most accurate, there are older methods which are still used to prove biological relationships. These include ABO blood group typing, using leukocyte antigen antigens or by analyzing enzymes and proteins between the two individuals.

Along with DNA, other current tests include polymorphism or RLFP and polymerase chain reaction or PCR. In addition, paternity testing can also take place in the womb while a woman is still pregnant through blood draws and comparisons. While this is the case, DNA tests are still the most advanced and accurate of all such tests.

When being used for legal reasons, there are specific factors which must be included during DNA tests. One of the most important factors is that those seeking such tests choose a reputable firm which has authority to provide legal DNA tests. For, there is a percentage related to the DNA match involved in the process which follows the chain of custody often used in the process.

In most cases, companies providing such tests can be found online or in local directories. While this is the case, when looking for tests with regards to legal reasons, it is important to use a reputable firm with a history of accuracy. It should also be noted that those seeking a test for legal reasons must also provide multiple forms of identification as often required by law.

Lastly, the evidence must be so strong that a judge or other official can be as close to 100% sure as possible that the test results are accurate. In most cases, it is advised that the evidence submitted is stronger than that of DNA found in a number of civil or criminal cases. For, the results must show beyond a reasonable doubt that the two individuals share the same DNA before any legal action such as obtaining child support or filing for adoption of a child can be finalized.

Recently, authorities working in the area of immigration such as France, Australia, Canada, the United Kingdom and the United States have been requesting that immigration petitioners asking for custody and beneficiaries of such requests provide voluntary DNA tests before being reunited. While this is the case, only a few countries have moved forward with processing such request.
