DOT urine drug testing comes with strict, detailed procedures—especially when something doesn’t go according to plan.
 
What if a donor’s sample is cold? What if they try to substitute a fake specimen? What if they simply can’t provide a sample at all?
 
Can you and your staff confidently recall every step for each of these “what if” situations?
 
Our DOT Drug Testing Collection Flowchart lays out every scenario in a clear, easy-to-follow visual algorithm. It’s perfect for keeping your collections on track, ensuring compliance, and reinforcing training for new and experienced collectors alike.
 
Printed as a durable, laminated 11x17 poster, it’s designed to mount right on your collection site or laboratory wall—so the right answer is always within reach.
