What cut-off levels do First Check Home Drug Tests use for detecting drugs in urine?
First Check Home Drug Tests conform to all cut-off levels and specifications published by SAMHSA (the Substance Abuse and Mental Health Services Administration). The cut-off level for each drug varies (depending on the type of drug) and is measured in nanograms (ng/ml). Although First Check Home Drug Tests are designed to detect a very small amount of a drug in urine, if the amount is below the established cut-off level, you may test negative for that drug even though you may have taken the drug. †The Substance Abuse and Mental Health Services Administration (SAMHSA), has set “cut-off” levels when testing for marijuana, cocaine, amphetamine, opiates (heroin), PCP, ecstasy and methamphetamine. First CheckTM 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 if the drug level is below
