Paternity test determines the genetic trace of the member of the family subject to the study. Comparing the genetic trace of the supposed father and the child or foetus, we could know their biologic filiations. As well as the paternity test they can also be done distant or close relatives test.
The procedure to conduct a paternity test through DNA analysis is very simple, but it changes depending if it is an informative test, for private use or if it needs a report with legal validity. Only biological samples of the son/daughter and the alleged father are needed. The biological sample of the mother is not essential. The easiest way to obtain the biological samples directly is to do an oral smear, using cotton buds, to collect the cells of the oral epithelial or saliva.
Paternity test for private use: This paternity test has no legal validity and the names of the people involved do not appear in the report. The sample taking can be carried out at the subject’s house and he/she can receive the results at home. For the sample taking you can ask us for a kit for the paternity tests that we will send you with accurate directions or you could pick it up yourself from any of the Instituto Bernabeubranches.
The procedure is very easy. On the kit that you will receive, you will find sterile cotton buds, with which you would need to rub the internal side of the mouth of the subjects involved. Use the samples carefully. Use protection to touch the cotton buds. Once you have taken the samples and you have packed them properly under the directions given, you should send them to us with the corresponding forms.
Paternity test with legal validity: It is conducted when an expert report is needed that includes the names of the people involved and that can be used in a Court. The admissibility of this paternity test in Court depends on the correct process of taking and identifying the sample. Therefore, the sample taking can only be carried out by health or law professionals, who will identify and custody the samples in order to guarantee their authenticity and integrity in every moment.
