Term Description

Submitter's referral laboratory uses what is usually considered a confirmatory method (e.g. LC/MS/MS) as the initial method for this analyte and then repeats the measurement with the same high accuracy method on tests that are positive in the first run to confirm them. Results (e.g. positive/negative) are based on a threshold of 1.0 ng/mL.

Part Description

LP172774-4   JWH-018
JWH-018 (1-pentyl-3-(1-naphthoyl)indole) is a synthetic cannabinoid and a scheduled I controlled substance. It is an analgesic chemical from the naphthoylindole family that acts as a full agonist at both the CB1 and CB2 cannabinoid receptors, with some selectivity for CB2. It produces effects in animals similar to those of THC, a cannabinoid naturally present in cannabis, leading to its use in synthetic cannabis products. Research has shown that the parent compound is extensively metabolized prior to excretion and, as a result, present at very low levels in urine samples. Its metabolites are thought to be better targets for assays. Copyright Text is available under the Creative Commons Attribution/Share-Alike License. See for details. Source: Wikipedia, JWH-018
