DNA Relationship Testing
DNA relationship testing confirms whether genetic links exist between alleged relatives. This type of test can be performed between various relatives including siblings, grandparents and their grandchildren or aunts and uncles with their nephews or neices.
Why do a DNA relationship test?
Generally, people might opt to do such a test as a means of establishing paternity in cases where the father is not available and therefore, a straightforward father-child paternity test is not an option. In such cases a grandparentage test or an avuncular DNA test can substitute a paternity DNA test. Siblings may also do a sibling DNA test, which will indicate the type of sibling relationship: half siblings, full siblings or unrelated.
