![]() While urine testing is well suited to detect recent drug use for post-accident or reasonable. Unlike urine drug testing, which may only detect drug use within the past 2-3 days, hair testing is able to detect a pattern of repetitive drug use for up to 90 days. workforce, thereby helping employers to strengthen their workplace drug testing programs.įor more information about drug testing, visit our website. Our hair testing detects nearly twice the number of positives as our urine test. We continue to carefully monitor regulatory changes and industry trends to proactively create codes that reflect drug use patterns in the U.S. Inclusion of standard or expanded opiates.Inclusion of standard or expanded benzodiazepines.Client identifier (client number or group bill).This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes. It has not been cleared or approved by FDA. When requesting a new unit code mnemonic, the following information is required: This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. Yet, during the past 3 years, only 48% of the new unit codes created have testing volume associated with them. In non-regulated urine drug testing, our 5 most commonly used unit codes represent approximately 30% of our total testing volume. We create new unit codes for regulatory changes, specific cutoffs, and client requests. Test codes are used to make up the desired unit code mnemonic requested for specimen testing. Test codes are 5-digit numbers assigned to a specific drug (such as amphetamine or cocaine) and can vary depending on specific screening cutoffs (i.e., amphetamine 1000 ng/mL vs amphetamine 500 ng/mL). They are used therapeutically to produce sedation, induce sleep, relieve anxiety, treat muscle spasms, and to prevent seizures. It has examined positivity rates for workplace drugs tested by the company on behalf of employers since 1988. These codes guide our laboratories towards the proper methods for accessioning and ultimately testing specimens.Ī common misconception is that unit code mnemonics and test codes are interchangeable. Drug Monitoring, Benzodiazepines, Quantitative, Urine - The benzodiazepine class of drugs are traditionally classified as depressants. The Quest Diagnostics Drug Testing Index (DTI) reveals insights into patterns of drug use among the American workforce. Unit codes mnemonics are 3- to 5-digit numbers followed by the letter “N” that can be found on every Quest Diagnostics Custody and Control Form (CCF) under the “drugs to be performed” section. Unit codes are one of those elements, and we plan to shed light on their purpose, as well as their importance in the Quest Diagnostics drug testing process. However, some steps tend to not receive their share of attention. We believe that every step in the drug testing process is important. Our Test Directory includes detailed information, guides and references for many of our tests. ![]()
