Drugs covered: alprazolam, alpha-hydroxyalprazolam, clonazepam, 7-amino-clonazepam, desalkylflurazepam, 2-hydroxyethylflurazepam, diazepam, lorazepam, midazolam, nordiazepam, oxazepam, temazepam, and alpha-hydroxytriazolam.

Identification of specific drug(s) taken by specimen donor is problematic due to common metabolites, some of which are prescription drugs themselves.

Positive cutoff:
20 ng/mL

The absence of expected drug(s) and/or drug metabolite(s) may indicate non-compliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, or limitations of testing. The concentration value must be greater than or equal to the cutoff to be reported as positive. Interpretive questions should be directed to the laboratory.

For medical purposes only; not valid for forensic use.
