Urine drugs of abuse
SPECIMEN COLLECTION
Redwood Toxicology Laboratory provides suggested specimen collection guidelines ONLY. It is the responsibility of individual collection agencies to adopt their own policies and procedures according to their needs in compliance with individual state and federal regulations.
Laboratory drug and alcohol test results are often used in legal proceedings. The manner in which specimens are collected and handled is very important. Specimens must be handled and controlled by collection site personnel throughout the collection process.
Directly observed urine collection is the best means to ensure specimen integrity. However, outside of probation and parole and some drug rehab environments, the question of civil rights arises. A uniform urine and oral fluid collection process, regardless of the testing environment, should be followed.
