Paternity DNA Testing
By Seth Miller
Tip! Home kits contain the exact same collection tools, as are used at a lab, and the results will be processed in the same way. But not all labs are accredited for processing DNA paternity tests.
DNA paternity testing, also referred to as parentage testing, uses DNA, or deoxyribonucleic acid, the biological basis of heredity, to prove or disprove the relationship between the child and the supposed father. The accuracy of paternity DNA testing is backed by the scientific fact that half of a person’s DNA comes from the father while the other half comes from the mother.
DNA paternity tests are used to check the similarity of the DNA components of the alleged father and the child. DNA samples are taken from the child, the assumed father, and the mother, which are then compared and analyzed using sophisticated machines. A buccal swab, very similar to a cotton swab is rubbed against the inside part of the cheeks of the people to be tested to gather cheek cells from which the DNA sample will come from. DNA is first purified then prepared for testing.
Testing DNA subjects the samples to a battery of at least sixteen DNA markers. These markers provide genetic profiles for each of the persons being tested. The child’s DNA profile is then compared with the profiles of both the mother and the supposed father to confirm whether or not the child has indeed inherited half of the genes of the alleged father. Statistical analysis using specific computer programs to calculate the possibility of paternity is then used to establish the possibility of the parentage.
Tip! Home DNA paternity test kits are not accredited, unless certain procedures are followed. These include photo identification of the person taking the test, as well as having it witnessed by a third party, without an interest in the outcome.
There are a number of DNA paternity tests available to determine the relationship of the child and the supposed father. DNA analysts will evaluate which paternity DNA test would best fit the client’s situation and needs. Even the collection of the sample will be scheduled based on the most convenient time for the client. Most DNA testing laboratories will have the results ready within five days or less upon receiving the samples.
