Legal DNA testing follows strict chain-of-custody procedures and can be used for court, child support, custody, or immigration cases. Peace-of-mind testing is for personal knowledge only and is not court-admissible.

DNA testing is highly accurate when performed by accredited laboratories. Relationship DNA tests including paternity, maternity, sibling, grandparent, and other family relationship testing analyze specific genetic markers to determine whether individuals share a biological relationship. When a biological relationship is confirmed, results typically show a probability of 99% or greater, and when individuals are not related, results will show 0% probability of relationship.
