DNA Relationship Test: Grandparent, Sibling, Aunt/Uncle and Family Reconstruction

When a direct paternity test is not possible, a relationship DNA test can help establish biological connections between other family members. It is often used when an alleged parent is unavailable, deceased, or unwilling to test. Testing is performed by an AABB-accredited laboratory.

Choose your test:

• Grandparent test: determines whether a child is biologically related to one or both grandparents.
• Sibling test: determines whether two people share one or both biological parents (full siblings, half siblings, or unrelated).
• Aunt / Uncle (avuncular) test: determines whether a child is biologically related to the sibling of an alleged parent.
• Family reconstruction: combines available relatives to establish relationships when key individuals cannot be tested.
