DNA Relationship Testing
DNA relationship testing can assist to determine whether there really are biological links between relatives. This type of test can be performed between various relatives, including siblings, grandparents and their grandchild or aunts and uncles with their nieces or nephew.
Why do a DNA relationship test?
Generally, people might opt to do such a relationship test as a means of establishing paternity in cases where the alleged 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.
