*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.

† First Check® Home Drug Tests use specific “cut-off” levels. Screening tests may not detect amounts of drugs in a sample that are below the cut-off level. Even though some level of drug may be present in a sample, the sample would still be considered a Negative Result if the drug level is below the cut-off level.
