Just like blood testing, saliva testing detects the presence of parent drugs and not their inactive metabolites. This results in a shorter window of detection for cannabis by saliva testing. [23] Delta 9 THC is the parent compound. If a saliva sample is tested in a lab, the detection level can be as low as 0.5 ng/mL (up to 72 hours after intake ...
2 to 3 days in blood, up to 2 weeks in blood of heavy users [12] However, it depends on whether actual THC or THC metabolites are being tested for, the latter having a much longer detection time than the former. THC (found in marijuana) may only be detectable in saliva/oral fluid for 2 to 24 hours in most cases, though in rare cases has been ...
In 2005 Stroehle, et al., determined that saliva detection of IgG antibodies against Toxoplasma gondii had a sensitivity and specificity of 98.5% and 100%, respectively. [63] A study published in 1990 demonstrated the diagnostic utility of saliva IgG testing in identifying neurocysticercosis secondary to Taenia solium. [64]
The Duquenois reagent is used in the Rapid Modified Duquenois–Levine test (also known as the simple Rapid Duquenois Test), which is an established screening test for the presence of cannabis. The test was initially developed in the 1930s by the French medical biochemist Pierre Duquénois (1904–1986) and was adopted in the 1950s by the ...
The U.S. Supreme Court tackled a case on Tuesday involving a New York state man who was fired from his job as a commercial truck driver for failing a drug test after taking cannabidiol, or CBD ...
As an example the SAMHSA cutoffs for cannabinoids are 50 ng/ml for the immunoassay and 15 ng/ml as confirmed by GC/MS. [6] Immunoassays that do not conform with SAMHSA, featuring a cutoff of 20 ng/ml, have been shown to produce false positives from passive inhalation of marijuana smoke.

Oklahoma Statute 47 § 11-902 makes it unlawful to drive or be in actual physical control of a vehicle who has any amount of cannabis or one of its metabolites or analogs in their "blood, saliva, urine or any other bodily fluid at the time of a test . . . within two hours after [their] arrest." [76]
