You may believe that paternity testing is only required when a mother is unsure of who the biological father of her child is, but this is only one of the many applications of a paternity test.

Paternity testing is undertaken for a variety of personal and legal reasons, including family medical concerns, adoption, child support, inheritances or the seeking of citizenship in another country. If you are considering paternity testing as an option, contact a specialist firm like The Genetic Testing Laboratories for more information.

DNA Testing

DNA testing is where an individual’s DNA markers are examined for the purpose of identification or determining the relationship between two people. It’s extremely accurate and can establish fatherhood at a certainty of more than 99%.

The DNA in our bodies is the same in our skin, muscles and bones, meaning that it doesn’t matter where the sample is taken from. Individual genetic code is repeated over and over again throughout our bodies in an identical form and does not change over the course of our lives.

What Happens Next?

A paternity test is usually carried out with samples of blood from the child, mother and supposed father. Only a very tiny amount of blood is required for the process and some testing laboratories will ask for a swap from the inside of the cheek or a hair sample instead.

Half of the child’s DNA fragments come from the mother and half from the biological father. If the child’s DNA contains fragments that can’t be matched to the supposed father, he can be excluded as the child’s biological father.

Additional Information

The results of DNA testing are admissible as court evidence and should be strictly confidential if gathered by a reputable testing firm. There is no age limit for DNA profiling and the test can be completed if one or both parents are deceased or if the child is still in the womb, using amniotic fluids of CVS samples.

It’s possible to perform DNA paternity testing without a sample from the mother, but these tests often take longer and are less accurate. A doctor’s note is not usually required for a paternity test to be performed, but if the child is under 18, parental consent must be provided for it to go ahead.
