At Paternity For Life, we are following all advice provide by both the UK Government, local health authorities and the World Health Organization (WHO) and taking extra precautionary steps to ensure the health and safety of our laboratory staff and customer service team to minimise any disruption to testing
Please be advised our laboratory is still operational, and we are currently not experiencing any delays with processing of samples.
For our Legal Collection Appointments, Paternity For Life recommends using WJ Legal. WJ Legal is a Legal Forensic Sampling Company who can attend your home address for collection of your sample. All WJ Legal Sample Collectors are forensically aware and can safely and hygienically take all needed samples. Our collectors already enforce strict hygiene practices during collections but will be taking extra precautions over the coming weeks including the use of gloves, face masks and sterile wipes.
That being said, if you are experiencing any virus-like symptoms or have travelled overseas in the past 14 days, we recommend delaying your collection or rescheduling your appointment to a later date.
If you have any questions or concerns, please don’t hesitate to contact our friendly staff on 0330 133 1944
Relationship DNA testing can be performed on individuals that share common relatives, such as siblings, aunts, uncles, nieces, nephews, grandparents, cousins, etc.
A relationship DNA test is suited for cases where an alleged parent is not available for the testing of a direct parent-child relationship. This may be because the parent is deceased, unwilling or unable to participate in testing. In these cases, extended relationship DNA testing can be carried out to determine whether there is a relation between the persons being DNA testing.
Extended Relationship Analysis – A DNA profile is created for each of the persons to be tested. A statistical model and database are used to compare the profiles and calculate how likely it is for the alleged relationship to exist.
The Y-Chromosome Test, or Y-STR test, can help male relatives to establish if they share a biological father or common paternal line. The Y-Chromosome is passed on virtually unchanged through the paternal line and therefore can be used to establish if a relationship exists.
Unlike Paternity or Maternity DNA testing, Extended Relationship DNA Testing cannot give a conclusive result of whether or not a relationship exists between the persons being tested. This is because Extended Relationship DNA tests involve comparing less direct relationships than that of a parent and child. A child will inherit 50% of their DNA from each parent, allowing for a conclusive result to be given in the case of Paternity or Maternity. Extended family members, such as aunts, uncles and grandparents will share a lower percentage of DNA with nieces, nephews or grandchildren.
Instead, the results will show the likelihood of a relationship between the tested persons.
If you are unsure of the DNA test you need, please contact us to discuss your particular case. We can help determine which DNA test would be best suited for you based on what it is you are looking to confirm through DNA testing and what the alleged relationship is between the persons to be tested.
Paternity For Life advises that the results may be inconclusive for an Extended Relationship DNA test. This is not due to laboratory error, but due to the difficulty in comparing DNA between individuals in extended relationships. The more degree of separation between two individuals, the less DNA is shared between the two and the harder it is for our extensively validated DNA tests to distinguish two related individuals from the general population and therefore is more likely to produce an inconclusive result. Paternity For Life does not recommend this DNA testing in cases of more than 3 degrees of separation.
*Please note: No testing costs will be refunded in the case of an inconclusive results.
