What We Test For

LVT uses Liquid Chromatography and Tandem Mass Spectrometry (LC/MS/MS) methods to detect the parent compounds as well as their metabolites in the following drug classes:

  • Opiates, Opioid Analgesics, Barbiturates, Benzodiazepines, Anticonvulsants, and Muscle Relaxants such as 7-Aminoclonazepam, Alpha-Hydroxyalprazolam, Butalbital, Carisoprodol, Codeine, Cyclobenzaprine, Dihydrocodeine, Fentanyl, Gabapentin, Hydrocodone, Hydromorphone, Lorazepam, Meprobamate, Methadone, Morphine, Naltrexone, Nordiazepam, Norfentanyl, Norhydrocodone, Normeperidine, Noroxycodone, Oxazepam, Oxycodone, Oxymorphone, Phenobarbital, Pregabalin, Tapentadol, Temazepam, and Tramadol
  • Suboxone Components such as Buprenorphine, Norbuprenorphine, and Naloxone
  • Drugs of Abuse such as 6-Acetylmorphine, Benzoylecgonine, Cannabinoids, MDA, MDMA, and Phencyclidine
  • Stimulants such as Amphetamine, Atomoxetine, Methylphenidate, and Methamphetamine
  • Antidepressants such as Amitriptyline, Duloxetine, Fluoxetine, Norfluoxetine, Norsertraline, Nortiptyline, Norvenlafaxine, Quetiapine, Paroxetine, Sertraline, Trazodone, and Venlafaxine
  • Sleep aids such as Zolpidem, Zaleplon, and Zopiclone

These panels have been created by LVT to provide the most comprehensive testing procedures for a variety of clinical applications. Any drugs not listed can be developed and added to any panel by request within a matter of weeks. 

LVT is currently focused predominantly with urine specimens as metabolite detection provides the most definite results, cutting down in false positives through cross reactivity and adulteration. Metabolite detection is the only available method to rule out sample adulteration through specimen dosing.

Oral Fluid Testing for exam room specimen collection is also available at LVT for confirmation testing only. This is useful in patients unable to void or when adulteration is expected.
