cannabinoid detection times. The objective of the current research was to examine the time course of THC, 11-OH-THC, and THCCOOH elimination in urine in subjects with a history of chronic, heavy cannabis use, and to test the efﬁcacy of THC and 11-OH-THC as urinary biomark-ers of recent cannabis exposure. Participants resided on a secure

Overview of Oral Fluid Testing Oral fluid (OF) tests detect THC and other drugs that are exuded from the body into the saliva after having taken the drug. The profile of THC in oral fluid is similar to that of blood, spiking at high levels (~ 100s ng/ml) early on then falling to lower levels that remain detectable (> 0.5 ng) for hours or days after

The average THCCOOH detection times of the last specimen by EIA and GC–MS were 42 ( 10; 2–72) and 58 h ( 6; 16–72), respectively. Considering the non-invasive nature of oral fluid collection and improved detection of recent marijuana use compared to urine testing, it was concluded that oral fluid testing for THC offers specific advantages ...

hours in occasional users and 3 to 13 days in regular users. THC is detectable (LOD 1 ng/mL) for approximately 5 hours in plasma and 10 hours in urine (LOD 10 ng/mL). THCCOOH can be detected much longer, and a detection time (LOD 5 ng/mL) of 25 days has been reported.21 A study carried out in Lu¨beck with 52 volunteers admitted to a ...

The DRI THC Assay is a homogeneous enzyme immunoassay using ready-to-use liquid reagents.6 The assay uses specific monoclonal antibody which can detect the major metabolite of ∆ 9-THC in urine. The assay is based on the competition of a drug ...
