368 © Approximately 24 million urine drug tests were performed annually in the United States at a cost of about $1.2 billion per year, according to a 1994 study by the Committee on Drug Use in the Workplace of the National Research Council and the Institute of Medicine and commissioned by the National Institute on Drug Abuse. [...] Key Method T1 outlines the advantages and disadvantages of urine specimens for DAU …Expand
Appropriate Use of Drug Testing in Clinical Addiction Medicine
TLDR
This document is intended to clarify appropriate clinical use of drug testing in addiction medicine and aid providers in their decisions about drug testing for the identification, diagnosis, treatment, and recovery of patients with, or at risk for, addiction. Expand
Rapid analysis of cocaine and metabolites in urine using microextraction in packed sorbent and GC/MS
TLDR
An ultrafast and fully validated procedure for the simultaneous detection and quantification of cocaine and its two main metabolites, ecgonine methyl ester and benzoylecgonine, in urine using microextraction by packed sorbent and GC-MS is described. Expand
Screening of cardiovascular agents in plasma with LC-MS/MS: A valuable tool for objective drug adherence assessment.
TLDR
An assay including 52 compounds and metabolites, covering over 95% of the antihypertensive and antithrombotic agents available worldwide, shows that using the CR cut off values has a significant and relevant effect on patient adherence classification. Expand
Relation between bloodand urine-amphetamine concentrations in impaired drivers as influenced by urinary pH and creatinine
TLDR
Investigating whether a quantitative relationship existed between blood and urine concentrations of amphetamine in the body fluids of drug-impaired drivers apprehended in Sweden found this stimulant is the major drug of abuse in this country. Expand
Erratum to: Earwax as an alternative specimen for forensic analysis
TLDR
The 12 drugs could be quantified from the earwax specimens of the users successfully, showing usefulness of earw Wax specimens, because of its noninvasive sampling and the storage of drug(s) for relatively long time together with its being relatively less contaminated by environmental impurities. Expand
A dilute-and-shoot flow-injection tandem mass spectrometry method for quantification of phenobarbital in urine.
TLDR
This feasibility study shows that the dilute-and-shoot flow-injection method can be a general way for fast analysis of drugs in urine and accurately and robustly quantify phenobarbital in urine without LC separation. Expand
Earwax as an alternative specimen for forensic analysis
TLDR
The 12 drugs could be quantified from the earwax specimens of the users successfully, showing usefulness of earw Wax specimens, because of its noninvasive sampling and the storage of drug(s) for relatively long time together with its being relatively less contaminated by environmental impurities. Expand
Assessing Adherence to Antihypertensive Medication by Means of Dose-Dependent Reference Plasma Concentration Ranges and Ultra-High Performance Liquid Chromatography-Ion Trap Mass Spectrometry Analysis
TLDR
The interpretation of plasma concentrations was found to be more sophisticated and time-consuming than that of urine screening results, and adherence could not be assessed in two cases due to measured plasma concentrations below the lower limit of quantification. Expand
RECENT ADVANCEMENT IN FORENSIC TOXIC DRUG ANALYSIS BY DESORPTION ELECTROSPRAY IONIZATION MASS SPECTROMETRY (DESI-MS)
Forensic toxicology is the analysis of biological samples to identify the presence of any harmful substances in the body. The three major sub disciplines in forensic toxicology are; human performanceExpand
Detecting Alcohol and Drug Use with the Touch of a Finger
The present study measured the accuracy and utility of the Veracity TouchScreener™ technology as a viable alternative to urine drug testing. 101 participants enrolled in court-ordered drug andExpand

TLDR
DAU panel standardization and DAU confirmation by request only have resulted in substantial reductions of laboratory workload and costs in a veterans population and may serve as a model for other patient populations with perhaps similar outcomes. Expand
Screening for Drugs of Abuse. I: Opiates, Amphetamines and Cocaine
TLDR
In order to provide an efficient and reliable service for drugs of abuse screening in urine, the laboratory should analyse 20-30 samples per week, and the staff should include a scientist with special expertise in the subject, according to the manufacturer's protocols or by modified methods that have been rigorously validated. Expand
Under the Influence? Drugs and the American Work Force
TLDR
The scope ofdrug use by the workforce, the impact of drug use on work performance, and the effectiveness of drug intervention programs are assessed to assess the scope of drugUse in the Workplace. Expand
Experience of a Laboratory Service for Drug Screening in Urine
TLDR
A large number of positive results were obtained for benzodiazepines, cannabinoids, methadone and opiates (mainly dihydrocodeine); only a limited number of urines gave positive results for amphetamine and related stimulants; cocaine metabolite was rarely detected in samples. Expand
Quinolones and false-positive urine screening for opiates by immunoassay technology.
TLDR
Greater attention to the cross-reactivity of quinolones with immunoassays for opiates is needed to minimize the potential for invalid test interpretation. Expand
The effects of adulterating agents on FPIA analysis of urine for drugs of abuse.
TLDR
The results of pH measurement on adulterated samples verified its utility in identifying some samples adulteration with interfering agents, but other adulterants that cause substantial effects would not be identified by pH measurements alone. Expand
Mechanism of false-negative urine cannabinoid immunoassay screens by Visine eyedrops.
TLDR
Results of ultrafiltration studies with Visine suggest that 9-carboxy-THC partitions between the aqueous solvent and the hydrophobic interior of benzalkonium chloride micelles, thereby reducing the availability of 9-vehicle-based cannabinoid assays in antibody-based assays. Expand
Adulterants causing false negatives in illicit drug testing.
TLDR
If urine drug testing is to be conducted, pH, relative density, and appearance should be assessed and suspect specimens should be rejected, because EIA assays for illicit drugs can be invalidated by specimen adulteration producing false-negative results. Expand
Effect of urinary pH on the disposition of methadone in man
TLDR
The present experiments demonstrate that pretreatment either with ammonium chloride or bicarbonate had profound effects on both the distribution and elimination kinetics of methadone. Expand
Concentrations of morphine and codeine in serum and urine after ingestion of poppy seeds.
TLDR
A positive finding of morphine or codeine in blood and urine may sometimes be due to ingestion of poppy seeds, as measured in commercially available poppy seeds and in serum and urine samples from healthy adults who had ingested these poppy seeds. Expand
