Hi Jared, I have a question. My husband has been out of rehab for 107 days, he’s stayed clean and is taking the pill form of Naltrexone. He has a pre-employment hair test for a much better paying job tomorrow. I measured his hair (It hasn’t been cut since before rehab) and it’s just a little over the required ″. He had a problem with opiates (Loratab) and had taken an adderall a few weeks before rehab (No prescription) since it’s been 107 days do you think he has a decent chance of passing this since he’s been clean? And can the Naltrexone (he has a prescription) cause a false positive?
There are five primary color-tests reagents used for general screening purposes. The Marquis reagent turns into a variety of colors when in the presence of different substances. Dille-Koppanyi reagent uses two chemical solutions which turns a violet-blue color in the presence of barbiturates. Duquenois-Levine reagent is a series of chemical solutions that turn to the color of purple when the vegetation of marijuana is added. Van Urk reagent turns blue-purple when in the presence of LSD. Scott Test's chemical solution shows up as a faint blue for cocaine base.
