DNA Paternity Testing Guide from Who'zTheDaddy in UK and Canada
DNA Paternity testing uses genetic fingerprinting to determine the probability of two individuals being in a genetic father-child relationship. Whilst many different methods of genetic fingerprinting are available, by far the most advanced and precise technique is DNA (deoxyribonucleic acid) testing.
A DNA test takes a sample of the child's DNA and compares it against a sample of DNA from the suspected father. These samples are quick and easy to collect, requiring nothing more than a swab taken from the inside of the cheeks of both parties. The swab looks much like a regular cotton bud, but contains chemicals which preserve the DNA sample and will enable it to survive transit to the laboratory. Leftover samples are destroyed once the necessary tests have been performed.
The DNA of a child is never a hundred percent identical to that of either parent, which is why results are given in terms of probability. During fertilisation of an egg, donor DNA from the father's sperm mingles randomly with DNA from the mother's egg to create a new and unique set of DNA for the child. Because this DNA can only come from the parents, false positive results are technically impossible. It's extremely important that all tests be carried out twice and that laboratory staff undergo regular proficiency tests.
It is possible to guarantee exclusion of a suspected father from paternity if none of his DNA traits are exhibited in the child. In most cases where there is a direct father-child relationship the probability is very high indeed – over 99%.
DNA Paternity Test
The likelihood of establishing paternity increases if the child is male. The Y chromosome is passed down directly from father to son and is not only useful for paternity testing, but also for family tree research. As the Y chromosome does remain identical – barring natural mutation – results are even more precise if both parties are male (similarly the X chromosome is directly passed down between mother and daughter).
Therefore although DNA paternity test results are expressed as a percentage, they are extremely reliable and highly indicative of whether the potential father is truly the genetic parent of the child in question: a low percentage match is simply a negative result; a high percentage match is a positive one.
The usefulness of paternity tests results in legal cases varies from country to country, but in most cases the results must come from an accredited testing facility to be admissible in court.
In the UK, there are further considerations to be had in obtaining samples for testing: the Human Tissue Act 2004 renders it illegal to have human material without consent if the intent is to analyse its DNA. A court can order a Paternity test should there be no consent, however, so all is not lost.
In Canada, a court may order blood tests, but the presumed father may refuse to give them and cannot be found in contempt for doing so. However, refusing to give a sample for a court-ordered test may lead to the court drawing its own conclusions.
DNA testing for paternity is highly reliable, results are repeatable and ultimately the results have many uses, from tracing lineage to bringing peace of mind.
