The Sirchie NARK II Duquenois-Levine Reagent (10 Tests) is presumptive test designed to identify THC in Marijuana. Court acceptance of the Duquenois-Levine Reagent has been established through Frye Hearings and is the singularly most reliable field test manufactured. To eliminate potential false positives, always agitate the 1st ampoule sixty (60) seconds before continuing with the 2nd and 3rd ampoules.
