DNA Paternity Testing: The Facts (Guest Post)

DNA testing isn’t just carried out at the instructions of detectives and investigators in television crime dramas. The real-life applications of DNA testing are numerous and include tests to determine the biological parentage of a child. If you want to know more about paternity testing or apply for a test, get in touch with a firm that specializes in this kind of testing, like Who’z The Daddy?

What is DNA?

DNA, or Deoxyribonucleic acid, is a chemical found in the cells of our bodies. Every individual has a unique pattern of DNA (except in the case of identical twins) and this pattern is repeated in every cell. Our DNA is formed from birth and it does not change over the course of our lives. Half of this is contributed from the mother and half from the father, and it stores the information that allows genetic characteristics to be passed down through generations.

DNA Paternity Testing

DNA paternity testing is the most accurate way we have to determine whether there is a relationship between two people and these tests are admissible as evidence in court. Samples are taken from the child, mother and father in the form of a blood sample or swab from the inside of the cheek. DNA is separated and sorted to produce an individual profile for the child that can then be compared against the mother’s sample. Half of the DNA fragments should be consistent with the mother’s DNA profile and the remaining fragments will determine whether the alleged father is indeed the true biological father. Supposed fathers can be excluded if their DNA fragments are not consistent with the child’s profile. A statistical analysis will then take place to make sure that the results are true and accurate. Paternity testing can be undertaken without a sample from the mother, but these tests take longer to process.

Who Might Need a Paternity Test?

Paternity testing is undertaken for a variety of reasons. The main reason is usually for the peace of mind of a family, but it can also be required for issues of custody, adoption and the payment of child support. If you’re considering moving to another country and wish to prove a family tie to secure citizenship, a paternity test can be used. There is no age limit for a paternity test, but if the child is under 18, parental consent must be given.

How accurate are the results? Is it possible the test was wrong?
