Test Methodology

Quantitative Liquid Chromatography-Tandem Mass Spectrometry

Interpretation

Drugs identified: Arup: 11-Nor-9-carboxy-THC

Clinical Utility

This assay is used to aid in the diagnosis and treatment of cannabinoid use or abuse. This assay provides a preliminary analytical result Positive results are confirmed by chromatographic methods. The primary psychoactive component of marijuana is delta-9-tetra-hydrocannabinol (THC). The THC concentration determines the potency of the marijuana. THC primarily affects the cardiovascular and central nervous systems. There is no reliable method for predicting the degree of impairment from cannabinoid concentrations measured in urine at this time.
