Specimen:

Random Urine

Collection Medium:

Minimum:

Preferred Minimum:  5 mL urine
Adult/Pediatric Absolute Minimum:  2.0 mL urine

Rejection Criteria:

Specimens exposed to repeated freeze/thaw cycles.

Analytic Time:

5 days upon receipt at reference laboratory

Reference Range:

Drugs covered: alprazolam, alpha-hydroxyalprazolam, clonazepam,

diazepam, lorazepam, midazolam, nordiazepam, oxazepam, temazepam, and

For medical purposes only; not valid for forensic use.

Interpretive Data:

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, diluted/adulterated urine, 
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.

Gas Chromatography-Mass Spectrometry and/or Liquid 
Chromatography-Tandem Mass Spectrometry
