Turn Around Time:
1-3 days upon receipt at reference laboratory
Reference Range:
Drugs covered and range of cutoff concentrations. Note: some drugs are identified based on the presence of unique drug metabolites not listed below. Drugs/Drug Classes Range of Cutoff Concentrations Barbiturates 200 ng/mL Benzodiazepine-like: alprazolam, clonazepam, 20-60 ng/mL diazepam, lorazepam, midazolam, nordiazepam, oxazepam, temazepam, zolpidem Cannabinoids (11-nor-9-carboxy-THC) 20 ng/mL Ethyl Glucuronide 500 ng/mL Muscle Relaxant(s): carisoprodol, meprobamate 100 ng/mL Opiates/Opioids: buprenorphine, codeine, fentanyl, 2-300 ng/mL heroin, hydrocodone, hydromorphone, meperidine, methadone, morphine, oxycodone, oxymorphone, propoxyphene, tapentadol, tramadol Phencyclidine (PCP) 25 ng/mL Stimulants: amphetamine, cocaine, methamphetamine, 100-400 ng/mL methylphenidate, MDMA (Ecstasy), MDEA (Eve), MDA, phentermine
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 must be greater than or equal to the cutoff concentration to be reported as present. If specific drug concentrations are required, contact the laboratory within two weeks of specimen collection to request confirmation and quantification by a second analytical technique. Interpretive questions should be directed to the laboratory.

Results based on immunoassay detection that do not match clinical expectations should be interpreted with caution. Confirmatory testing by mass spectrometry for immunoassay-based results is available, if ordered within two weeks of specimen collection. Additional charges apply.

For medical purposes only; not valid for forensic use.
Comments:
Note: Creatinine concentration is also provided. The carisoprodol immunoassay has cross-reactivity to carisoprodol and meprobamate.
Methodology:
Qualitative Liquid Chromatography/Time of Flight Mass Spectrometry or Tandem Mass Spectrometry/Enzyme Immunoassay/Quantitative Spectrophotometry
