A legal DNA test is a type of DNA testing designed to meet specific legal requirements, ensuring that the results are admissible in court or other legal proceedings. These tests follow a strict chain-of-custody process to verify the identity of the individuals being tested and to maintain the integrity of the samples from collection to analysis.
