Barbiturates, Urine Screen with Reflex to Quantitation
Copy Utility
Useful for general screening in contexts of compliance and/or abuse. A screen with reflex testing is the preferred method for ruling out barbiturate exposure. For follow-up testing of a presumptive result, Barbiturates, Urine Quantitative (2012213) is preferred.
Qualitative Enzyme Immunoassay/Quantitative Gas Chromatography-Mass Spectrometry
Sun-Sat
1-4 days
Random urine.
Transfer 4.0 mL urine with no additives or preservatives to an ARUP Standard Transport Tube. (Min: 2.0 mL)
Room temperature.
Breast milk. Pharmaceutical preparation.
Ambient: 1 week; Refrigerated: 1 month; Frozen: 3 years
Screen cutoff concentration: 200 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, diluted/adulterated urine, or limitations of testing. The concentration at which the screening test can detect a drug or metabolite varies. Specimens for which drugs or drug classes are detected by the screen are reflexed to a second, more specific technology (GC/MS and/or LC-MS/MS). 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.
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.
If the specimen screens positive, then Confirmation/Quantitation by GC-MS (ARUP test code 2012213) will be added to confirm result. Additional charges apply.
80307; if reflexed, add 80345 (Reflexed Alt Code: G0480 )
