How can I order the Forensic Laboratories On-Site Oral screening devices?
To order the On-Site Oral screening devices, please call a Client Services Representative at (800) 282-6574. Oral Fluid THC Explanation Due to the limitation of current testing technologies, the detection of cannabinoids (THC) in oral fluids is problematic. There is very little evidence that THC in blood returns to oral fluids once it is absorbed into the bloodstream. However, the active component of marijuana, delta-9-THC, can be detected in oral fluid. During marijuana use (inhalation or consumption) THC is deposited in the oral cavity and can be detected for approximately 12-24 hours after use. To optimize the detection of marijuana, Forensic Laboratories suggests if marijuana use is suspected, to either submit the oral fluid specimen to Forensic Laboratories for delta-9-THC GC/MS testing or to simultaneously collect and screen a urine specimen for THC-COOH (primary metabolite in urine).
