How should chain-of-custody be maintained if a specimen is being used for legal purposes?

The main concept is keeping an unbroken, verifiable trail of who handled the specimen from collection to lab receipt so its integrity can be proven in court. The best approach is to maintain secure, documented custody at every step—from collection through transfer and receipt at the laboratory—so each person, time, and location is recorded, and tamper-evident seals and proper storage are used. This makes it possible to demonstrate that the sample was not altered or substituted and that the chain of custody is intact when presented as evidence. Lapses in documentation, or ad hoc notes that aren’t traceable or secure, can cast doubt on the sample’s authenticity and may render it inadmissible.
