Haw. Code R. § 11-113-27
Procedures shall be instituted to account for the integrity of each specimen by tracking its handling and storage from the point of specimen collection to final disposition of the specimen. These procedures shall require that a chain of custody form be used from the time of collection to the receipt by the laboratory and that upon receipt by the laboratory an appropriate laboratory chain of custody form be used for the specimen or specimen aliquot within the laboratory. Chain of custody forms shall, at a minimum, include an entry documenting date and purpose each time a specimen or aliquot is handled or transferred and identifying every individual in the chain of custody. The chain of custody of the collecting site shall contain the "coded" identity of the individuals being tested. The laboratory chain of custody shall either use the coded identity of the collection site, or the accessioning number assigned by the laboratory, in which case laboratory chain of custody shall contain both the code and accessioning number.
