Preferred test to follow-up presumptive results. For general screening, Benzodiazepines Urine Screen with Reflex to Quantitation (2012225) is preferred.
Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Transfer 0.5 mL urine with no additives or preservatives to an ARUP Standard Transport Tube. (Min: 0.3 mL)
Specimens exposed to repeated freeze/thaw cycles.
Ambient: 1 week; Refrigerated: 1 month; Frozen: 3 years
|Drugs Covered||Cutoff Concentrations|
Methodology: Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Drugs covered: alprazolam, alpha-hydroxyalprazolam, chlordiazepoxide, clonazepam, 7-aminoclonazepam, diazepam, lorazepam, midazolam, alpha-hydroxymidazolam, nordiazepam, oxazepam and temazepam..
Positive cutoff: 20 ng/mL unless specified below:
Alprazolam 5 ng/mL
Alpha-hydroxyalprazolam 5 ng/mL
Clonazepam 5 ng/mL
7-aminoclonazepam 5 ng/mL
For medical purposes only; not valid for forensic use.
Identification of specific drug(s) taken by specimen donor is problematic due to common metabolites, some of which are prescription drugs themselves. 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.
Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
