Grandparent, siblingship, and avuncular (aunt/uncle) DNA testing — when a standard paternity test isn’t an option.
Relationship DNA tests are used when the alleged father is unavailable, deceased, or unwilling to test. These tests analyze DNA between other biological relatives to determine family relationships with the same accuracy and reliability as traditional paternity testing.
Determines the biological relationship between grandparent(s) and a grandchild. Most effective when both grandparents participate. This test is valuable when paternity cannot be directly established.
Determines whether two individuals share one or both biological parents. Can test for full or half siblings, providing clarity when paternity of both parties is uncertain or when establishing biological relationships between siblings.
Determines the biological relationship between an aunt/uncle and a niece/nephew. Used when the alleged father is unavailable but a sibling of the father can participate in testing. An effective alternative when direct paternity testing isn’t possible.
