Other times a MRO is not needed and results are reported directly from the laboratory management system to the client. Results Reporting – In some circumstances results, regardless of the final result, are reported to a Medical Review Officer (MRO) who analyze the results before then releasing them directly to the client.– If the initial screening indicates a presumptive positive result, a specimen will undergo further confirmation testing. – If the screening results are negative, no further testing is needed. From there, all specimens go through an initial screening process which varies by specimen type. Testing Process – After entering the laboratory, specimens are accessioned into the laboratory management system.Upon receipt, specimens are removed from their packaging, sorted by specimen type, and moved to the laboratory floor. Once they arrive at the unloading dock, they are considered “received” and enter processing. Arrival – Drug test specimens reach our laboratories through many different modes of transit.Our Quest Diagnostics drug testing laboratories measure turnaround time at three major timestamps throughout the process. It’s an important concept to understand and to factor into the selection of a drug testing provider, as on boarding new candidates and getting current employees back to work as quickly as possible is often of paramount importance. Reflex tests are performed at an additional charge.Turnaround time is a commonly used term to measure the duration of time it takes to return a positive or negative drug test result to the employer. Please direct any questions regarding coding to the payor being billed.Īny Profile/panel component may be ordered separately. The CPT Codes provided in this document are based on AMA guidelines and are for informational purposes only.ĬPT coding is the sole responsibility of the billing party. Quantitative values cannot be used to assess the drug dose, because the drug is extensively metabolized and excreted in the urine. Urine drug test results equal to or greater than cutoff are reported as positive and results less than cutoff are reported as negative. Safest prescribing habits should include a combination of tools and laboratory test results to correctly detect drug use patterns. No single monitoring approach provides adequate information about the pattern or dose of patient drug use. Use of serum/plasma should be limited to anuretic patients, or where a patient's clinical appearance does not coincide with their prescribed medications. Urine or oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs. Therapeutic urine drug monitoring is important for ensuring compliance to treatment strategies, as well as ensuring non-diversion for illicit purposes. Presumptive positive screen results are reflexed to a more specific and sensitive liquid chromatography mass spectroscopy (LC/MS/MS) test. The test is a screening assay using a homogeneous enzyme immunoassay method of analysis. Oxycodone: Noroxycodone, Oxycodone, Oxymorphone Opiates: Codeine, Hydrocodone, Hydromorphone, Morphine, Norhydrocodone Marijuana Metabolite: Marijuana Metabolite If screen of drug class is positive, a confirmation of the drug class will be performed at an additional charge (CPT code(s): dependent upon the confirmed drug class).Ĭonfirmation includes the following analytes within their associated drug class:Īlcohol Metabolites: Ethyl Glucuronide (ETG), Ethyl Sulfate (ETS)Īmphetamines: Amphetamine, Methamphetamineīenzodiazepines: Alphahydroxyalprazolam, Alphahydroxymidazolam, Alphahydroxytriazolam, Aminoclonazepam, Hydroxyethylflurazepam, Lorazepam, Nordiazepam, Oxazepam, Temazepamīuprenorphine: Buprenorphine, Norbuprenorphine Specimen validity consisting of Creatinine, Specific Gravity, Oxidant, and pH testing. Initial screen of 6-Acetylmorphine, Alcohol Metabolites, Amphetamines, Benzodiazepines, Buprenorphine, Marijuana Metabolite, Cocaine Metabolite, MDMA, Opiates, Oxycodone drug classes. If this test code is not ordered with 39158, all medMATCH result codes will be DNR’d. If 39158 is ordered, all Drug Monitoring order codes will be treated as medMATCH. If you require medMATCH for this order code, you must also order code 39158 - Prescribed Drugs, medMATCH®.
