June 2017
Test method and reporting changes

Beginning June 26, 2017 Redwood Toxicology Laboratory will update the confirmation method for amphetamines in oral fluid tests to utilize LC-MS/MS. The cutoff level will remain unchanged at 15 ng/mL.

No action is required for customers that have been testing for these drugs. Confirmation of presumptive positive specimens will now use the updated methodology without any interruption in service.

As your dedicated laboratory partner, our goal is to provide tools that help optimize outcomes through state-of-the-art drug detection and scientifically credible data interpretation. By continuing to update methodologies to reflect current industry standards and efficient practices, we allow clients to receive tests faster and with increased performance.

Excellent service is always our top priority. If there is anything that we can do to improve your service experience, please do not hesitate to contact a Toxicology Support Representative at 800.255.2159, press option 5.
