Testing Delays

Redwood Toxicology Laboratory is experiencing delays in reporting confirmation testing results due to courier disruptions and staffing shortages. Our laboratory is focused on returning to normal turnaround times as our top priority. We are working diligently to correct this situation and commit the necessary resources to this recovery. Our target recovery is end of month. In the meantime, turnaround times on confirmations are trending at three to five days.

Thank you for your patience as we work through these challenges. We appreciate your business.
