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.

Change Reason

The Property has been changed from ACnc to reflect the new model for ordinal terms where results are based on a cut-off value.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
