Changes to oral fluid screening methods and test codes 12/19/11

Dear Client:
In December 2011, Redwood Toxicology Laboratory (RTL) will change the screening method used for oral fluid specimens from Enzyme-Linked Immunosorbent Assay (ELISA) to Enzyme Immunoassay (EIA), one of the industry's standards. As with the previous method, the new method is also enzyme-based and you can continue to rely on our screening's consistent reproducibility of results. Outcomes are precise, accurate, and dependable. The change to EIA will allow flexibility in requesting tests while maintaining fast turnaround time.

As a result, all oral fluid panel codes will change. No action is required on your part; you may continue to use your existing labels and chain of custody forms. Test requests will automatically be converted to the new panel code when your specimens arrive at the laboratory. When you receive your next laboratory supply order, your labels will be updated with the new panel codes.

With RTL's expanded 7-compound drug test, the positivity rates will be higher and clients will gain greater confidence in designer drug detection while taking advantage of the convenience and increased popularity of oral fluid testing.

Sincerely,
Redwood Toxicology Laboratory
