These tamper evident seals are used for chain of custody procedures in drug testing
The seals identify the presence of any tampering with the specimen containers or vials from the moment they are sealed until they are opened at the testing laboratory
After annotating the seals with donor identity information, remove the red adhesive seal from the liner and apply over the top of the urine container or vial
Press the adhesive on to the sides and top of the vial until securely snug
