Legal DNA relationship atests employ strict identification and witnessing protocols to ensure the correct individuals are being tested. During DNA sample collection, each participant is obliged to present two forms of identification. One of these must be a photo ID, and they must also provide a recent photograph. In addition, fingerprints are taken as an additional measure of identification. An impartial third-party specimen collector, who has no connection to the case or the individuals involved, oversees and documents the entire process.
