When it comes to DNA testing, there are a number of reasons individuals may wish to do so. While providing DNA to companies which provide information on ancestry and heritage is currently quite popular, there are other reasons such as legal paternity testing which can have both positive and negative connotations for those involved.
When DNA is used for legal issues related to determining whether or not there is a biological connection between two individuals, genetic fingerprinting is used to prove whether each individual shares the same biological markers. In most cases, this type of testing is used to determine whether an individual is the birth father of a child. Whereas, there are new maternity tests which can now show whether a woman is the birth mother of an individual.
With even newer DNA tests, the likelihood of grandparents and grandchildren having the same markers can now also be proved. For, while new DNA tests are now considered the most accurate on the market, older methods are still used in some areas. These methods include, ABO blood group typing, the use of leukocyte antigen antigens and by analyzing proteins and enzymes.
Polymorphism or RLFP and polymerase or PCR are two types of tests which are related to DNA matching. In addition, paternity tests can now be completed at any point during pregnancy. In the case of DNA matching in an unborn child, DNA is acquired from the individual believed to be the father and matched to that of the unborn child.
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, those seeking DNA tests for legal reasons are doing so for purposes such as adoption, immigration, social welfare benefits, inheritance or child support. As such, the testing needs to be provided a reputable source whom can provide accurate testing. To satisfy the chain of custody requirements, all parties being tested have to present positive identification such as a birth certificate and picture ID along with specimens collected by a third party professional with no relation to those being tested or interest in the results of the test.
The evidence necessary must be extremely clear with the ability to convince a judge or other official the results are accurate. In fact, the evidence must be even more convincing than most provided during a civil litigation case. As such, the results must provide accuracy beyond a reasonable doubt that the individual and child are related before any legal action such as adoption can be finalized.
Those working in this area related to immigration in countries such as the United States, United Kingdom, Canada, Australia and France have been requesting DNA tests to determine biological connections in situations in which birth certificates or other documents are not available. While this is the case, very few countries have actually began requiring individuals undergo such tests. For, it can often hard to assure that a test is accurate when the petitioners and beneficiaries can not provide valid forms of ID.
