Description
If it is not possible to obtain the DNA of the presumed father of the child, his paternity can be established or ruled out by analysing the DNA of his parents, i.e. the child’s grandparents. Thus, it is a determination of the grandparent-grandchild relationship. To make the result of the test unambiguous, the sample of the child’s mother must also be analysed. If this sample is not available, the reliability of the result depends on several circumstances, in particular the sex of the child. In this case, we recommend that you consult with us by phone or in person before ordering a test.
You send us the material for analysis and pay the price of the test. If you come to our laboratory in person, we will do the collection for you. We will perform the analysis, calculate the probability and send you a report with the test result by mail, email or you can pick it up in person. If you order the test, we will send you a collection kit by post (or you can collect it from us in person) with instructions for all participants to take a simple oral swab in the privacy and comfort of their own home. If an oral swab cannot be performed on a participant, we may try to obtain DNA from a non-standard sample. You send us the material for analysis and pay the price of the test. If you come to our laboratory in person, we will do the collection for you. We will perform the analysis, calculate the probability and send you a report with the test result by mail, email or you can pick it up in person. In this test, we test 15 or 19 (depending on the situation) sections of DNA, called STR markers, plus an additional section to determine the sex of the sample. If the mother of the child (grandchild) is also examined, the test either conclusively rules out or confirms the grandparent-grandchild relationship with a probability of at least 99.9%. If the child’s mother is not examined, the probability is usually at least 99%, but not always. In this case, additional DNA traits need to be examined, the choice of which depends on the sex of the child and other circumstances. These examinations may extend the test date and require additional costs. Therefore, if the sample of the child’s mother is not available, the price of the test and the date of execution depend on the specific situation.

The result of an anonymous test cannot be used as evidence in court because no one has certainty about the origin of the samples analysed except the test participants themselves. However, the laboratory test itself is done in the same way as the forensic determination, so the result must also be the same.
The test can also be carried out in the form of a forensic expert opinion.
