Sibling DNA Tests
Sibling DNA testing is used to determine whether two individuals have biological parents in common, when one or more of those parents are not available for testing. This can be used in a number of different scenarios, for example, when the alleged father is deceased, reuniting long-lost relatives separated through adoption and aiding disputes over inheritance.
dadcheck® is able to provide DNA testing services to determine whether two people are related as:
Full siblings: i.e. they share the same biological mother and father.
Half siblings: i.e. they share the only one biological parent.
On average full siblings will have more DNA in common than half siblings and similarly, half siblings with have more DNA in common than unrelated people. The statistical analysis performed following the generation of unique DNA profiles will determine the most likely relationship based on the DNA profiles generated.
Prices for a sibling test start from £309 inc. VAT
Please note: As a sibling test is trying to ascertain the existence of a biological relationship with another person e.g. potential father, without actually testing their DNA directly. A sibling test therefore is not as conclusive as a paternity test. As such, if any of the parents of either of potential siblings who are being tested are also available and willing to take part in the testing, we strongly recommend that they participate. This will help greatly with the statistical analysis of the test results and could improve the end result. Sibling tests are used to ascertain which is the most likely relationship given the DNA evidence generated.
