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 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 establish the extent of the sibling relationship: half siblings, full siblings or not siblings.
