Carboxy tetrahydrocannabinol [Mass/volume] in Saliva (oral fluid) by Confirmatory method

Active

Part Descriptions

LP14468-0   Carboxy tetrahydrocannabinol
Carboxy THC is the major metabolite of cannabinoid found in urine, but is not related to source, time of exposure, amount, or impairment. Carboxy THC may be found in urine for 7-10 days following light or moderate use and as long as 4-6 weeks following heavy use. THC metabolites are stored rapidly in body fat following use and are released slowly over time. Source: Regenstrief Institute

LP14468-0   Carboxy tetrahydrocannabinol
11-nor-9-carboxy-delta-9-THC is the major metabolite (carboxy THC) in urine but is not related to source, time of exposure, amount, or impairment. Rapid storage of THC metabolites in body fat occurs after use. These substances are then released from storage sites slowly over time. A marijuana cigarette is made from the dried leaves of the plant, Cannabis sativa. The immediate effects of smoking marijuana include a faster heartbeat and pulse rate, bloodshot eyes, and a dry mouth and throat. The drug can impair or reduce short-term memory, alter sense of time, and reduce the ability to do things which require concentration, swift reactions and coordination, such as driving and operating machinery.

LP7565-7   Saliva
Saliva is produced primarily by the parotid, submaxillary, and sublingual glands. It is secreted at the rate of 0-3 milliliters per minute which is affected by various factors including anxiety, hydration and hunger. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Oral fluid is used to test a variety of analytes, including to test alcohol, HIV and other antibodies, therapeutic drugs and steroids, but its primary use is to test for drugs of abuse including amphetamines, cocaine and metabolites, opioids, methadone, cannabis and heroin.

Oral fluid (or saliva) is produced primarily by the parotid, submaxillary, and sublingual glands. It is secreted at the rate of 0-3 milliliters per minute which is affected by various factors including anxiety, hydration and hunger. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Oral fluid is used to test a variety of analytes, including to test alcohol, HIV and other antibodies, therapeutic drugs and steroids, but its primary use is to test for drugs of abuse including amphetamines, cocaine and metabolites, opioids, methadone, cannabis and heroin. The test procedures that use oral fluid for drug screening are usually similar to those for other specimens but adapted for oral fluid. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Drugs present in oral fluid are often the parent drug rather than a metabolite and tests kits reflect those differences. Concentrations of cocaine, amphetamines and some opioids in oral fluid are either similar or higher than concentrations in plasma. The concentration of tetrahydrocannabinol (THC) in oral fluid is similar to that of plasma, though in cases where recent ingestion has occurred, levels may be higher due to the significant local absorption in the oral cavity. Confirmatory testing on oral fluid using liquid chromatography-mass spectrometry (LC-MS) is highly sensitive and specific even on relatively small sample sizes. An increased understanding of pharmacokinetics in oral fluid has flourished inover the last ten years has allowed the correlation of . As a result, the concentrations of various drugs in oral fluid have been correlated to blood concentrations and the effects they have on the individual. PMID: 17268583 Source: Regenstrief LOINC
