DNA testing Louisiana is actually a relatively straightforward process. Because of the many crime dramas on television, most people consider themselves familiar with what is needed for the collection of a DNA sample, but the rest of the analytical process is something we don’t usually see. We understand that the DNA test leads to a comparison with another DNA sample, but how those samples are compared is usually beyond our experience. Because of our lack of familiarity with the entire DNA analysis process, handing over a DNA sample can seem intimidating. But by understanding the steps that lead from DNA extraction to DNA results you can be more comfortable with relying on a DNA test.
Since DNA is the most basic component of every individual, it can be taken from almost anywhere on a person’s body. However, there are certain parts of the body that more easily provide a large number of cells, and depending upon the DNA testing Louisiana that needs to be done, samples might be preferred from those areas. These large samples come from blood and from the soft tissues of the body, which includes skin. Often DNA samples are extracted through a blood draw, or through swabbing the interior of a person’s cheek, a method which gathers both skin cells and saliva. The cheek swab is usually the most preferred method because it is non-invasive but still gathers a sufficient number of cells. Saliva, as well as semen and hair root are alternative sources of DNA samples which are most often used in forensic testing in Texarkana, TX and Texarkana, AR, rather than for basic testing.
The actual process of DNA testing Louisiana involves comparing two samples of DNA. The sample that was taken from the individual is split into fragments, and those fragments are compared to another sample to see if they match. The amount of similarity between the fragments that is required for them to be a considered match will vary based upon the kind of DNA test being run. In paternity tests, 50% of the fragments must match for the test subjects to be considered related, while in grandparent testing only 25% of the fragments must match, and when testing to see if its an individual’s own DNA, 100% of the fragments must match.
While it is important to understand the DNA testing process, it is also important to rely on a testing service that you know will do the job well. Drug and Alcohol Testing Compliance Services has all the skills and experience necessary to conduct the DNA test in an efficient and professional manner.
