Legal DNA testing is used when results are required for court, immigration, or other official purposes. This testing follows strict chain-of-custody procedures to verify participant identity and ensure the integrity of each sample. Toxicology Now coordinates supervised collections and proper documentation so results meet legal and agency requirements.

Non-legal DNA testing is intended for personal knowledge only and does not require chain-of-custody documentation. This option offers a private, flexible, and cost-effective way to obtain DNA results for peace of mind or family information. Results are not valid for court or legal proceedings.
