Thank you for choosing Redwood Toxicology Laboratory. We encourage you to explore this welcome site to begin your experience with us and make the most of what we offer. Do you have questions about specimen collection and chain of custody? Do you need information on drug interactions and street names? We provide you the essential resources and training options for managing a successful drug testing program.
In an effort to maintain competitive laboratory testing prices, and to reduce the volume of problem specimens, we will begin charging clients for each specimen that is not prepared according to the defined protocols. Clients who are correctly preparing specimens will not see the additional charges applied.
Please review collection and labeling/shipping protocols carefully.
