Paternity DNA testing is in huge demand.  You should be fully aware that the paternity test result is a bit more detailed than a ‘yes you are the father’ or a ‘no you are not the father’. Many DNA testing companies want to show transparency by showing how your results were reached and thus, will provide you with a scientifically reliable paternity test report.

 How do I do A Paternity DNA test?

To have the paternity test carried out you will need to provide DNA samples of at least the child and alleged father. DNA sampling is nowadays very simple and straightforward – DNA testing companies will provide you with buccal swabs which you simply rub inside the mouth. Doing this will collect cheek cells along with saliva and these cheek cells are what scientists will use to extract DNA and create genetic profiles for the alleged father, child and mother (if she is included).

 Paternity Test Result: Inclusion

The paternity test result will show the DNA profiles of the alleged father and child. A DNA profile is basically an analysis of specific genetic loci (a locus is a location on your DNA); many companies will test 21 of these loci. The probability of paternity will be of 99.9% in a paternity test that does not include the mother’s samples (the probability of paternity increases if the test is carried out with the mother’s samples). The wording on the document you receive will be as follows for the inclusion: the alleged father ‘cannot be excluded as the child’s biological father’. This on careful reading means that the alleged father tested is in fact, the biological father of the child- the tested father cannot be eliminated (excluded) as the biological father.

 Paternity Test result: Exclusion

An exclusion of paternity happens when genetic loci on the profiles of the father and child do not match. The loci will be displayed in a table and you will be able to understand why the result turns out an exclusion by seeing the matches and non-matches between the profile of the child and father. The inclusion will be of 0% and the paternity test result will read the tested man ‘cannot be included as the child’s biological father’.

 Other related issues with Paternity Test Results

Earlier in the article we spoke about the genetic loci tested and that for an inclusion of paternity all genetic loci between alleged father and child should match. In some cases, there can be one marker which does not match between father and son. This can be due to a mutation. In such a case, the company will contact you as they will need to include the mother’s samples. In cases where two markers do not match, it is likely that the alleged father is not the father but a close relative of the child. The company you choose will help you fully understand your paternity test result should you find any difficult interpreting it. In the vast majority of times clients have no problems with their reports.
