DNA paternity testing is a term that is very confusing to many people although it is widely contemplated when it comes to proving paternity for child support. Many people really want to know what DNA means, what DNA paternity testing is, what it really involves and how accurate it can be before deciding to go for it. If you are one of these people, worry no more as you are not alone. Read through this article and get all your DNA paternity questions answered.
DNA is an abbreviation of deoxyribonucleic acid; a nucleic acid that has a set of all living organisms’ genetic factors. This nucleic acid is very specific to an individual organism and carries specific generic instructions that assist in building particular body structures such as RNA and proteins. The DNA segments that normally carry this information are scientifically called genes. Deoxyribonucleic acid is just like your body’s blueprint.
DNA paternity testing is the process of matching a donor’s DNA with another person’s, to see whether they are related. This practice involve a Buccal Swab sample of cells being swabbed from the inside cheek of a donor without any pain and then taken to a laboratory of choice for screening. Getting the results will entirely depend on the type of test one opts to use and the efficiency of that particular laboratory. The most common types of DNA paternity tests used today are RFLP and PCR. RFLP is by far more accurate of the two.
Now, how accurate is the DNA paternity test then? The accuracy of a paternity test entirely depends on the number of points (loci) tested from a child and their prospect parents. The higher the number of loci used the greater the accuracy of a DNA paternity test. Therefore, choose laboratories that uses many loci to test the paternity of a child and that that excludes prospect fathers whose DNA show variation in one or two DNA patterns on all tested points. This is a major AABB criterion that is widely used in the accreditation different DNA testing laboratories worldwide.
Two sets of results are normally involved in testing paternity. These are Exclusion and Inclusion paternity test results. In exclusive paternity test result, the focus is on separating prospect fathers whose DNA does not match with that of a child. In this test, results should not be less than 100% accurate. You will be excluded as the real father of that child without question if your DNA fail to 100% match with that of a child. Inclusive paternity results test on the possibility of a person being a father of a child. This test is not 100% accurate but it should at least be 99.9 to 99% accurate.
Having a DNA paternity test is not only a way to be sure about the paternity of a child but also the only reliable way to know the real parents of a child. You should however know that the paternity DNA test is very easy and painless. Though the test does not offer 100% accuracy, it gives at least give 99% to 99.9% results accurately. I repeat, use a large number of loci to test for paternity if you what to improve on the test’s accuracy or better still visit an accredited DNA analysis company that get more than 16 samples from an individual for screening.
