Test Code:
090-30-1962-01

Order Name:
Marijuana (Cannabinoids) (Urine), EIA *

 
Useful For:
1. Determination of cannabinoids (THC) in human urine.
2. The assay is intended for use in clinical laboratories.
3. This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrometry (GC/MS) is the preferred confirmatory method.

Clinical Information:
The principal active agent in marijuana and/or hashish that produces hallucinogenic and other biological effects is generally accepted to be Δ9-tetrahydrocannabinol (Δ9-THC). Δ9-THC is rapidly absorbed and almost completely metabolized by inhalation or through the gastrointestinal tract. Peak plasma levels of Δ9-THC occur within 10 minutes of inhalation and approximately 1 hour after ingestion. About 70% of a THC dose is excreted within 72 hours with 30% in urine and 40% in feces. Passive inhalation of marijuana smoke can result in an elevation of urine THC concentration as high as 10 to 40 ng/mL. In chronic users, THC may accumulate in fatty tissue faster than it can be excreted. This leads to longer detection times in urine for chronic users than for occasional users.
