*Benzodiazepines are detected dependent on whether they are long-acting (up to 10 days), intermediate-acting (up to 5 days) or short-acting (up to 2 days). In addition, other factors such as dose taken, route of administration, time of last dose and individual differences in pharmacokinetics will impact detection of the benzodiazepine.
† The Substance Abuse and Mental Health Services Agency (SAMHSA), has set “cut-off” levels when testing for marijuana, cocaine, methamphetamine, amphetamines, ecstasy, opiates, and PCP. First Check is manufactured to conform to those standards. Screening tests may not detect amounts of drugs in a urine sample that are below the cut-off level. Even though some level of drug may be present in a urine sample, the sample would still be considered Negative Result if the drug level is below the cut-off level.
