Serum, plasma, and postmortem blood treated with two volumes of N,N-dimethylformamide (DMF) and centrifuged, were directly analyzable by means of the EMIT d.a.u. reagents on the Syva Autocarousel in the same manner as urine. Cutoff values in milligrams (immunochemically cross-reactive analyte
Urine drug testing has been employed for punitive purposes by the Department of Defense since December 1981 (Memorandum 62884, Deputy Secretary of Defense Frank C. Carlucci). Federal Workplace Drug Testing Programs were initiated in response to Executive Order 12564 issued on September 15, 1986,
The EZ-SCREEN Cannabinoid/Cocaine test is a qualitative enzyme immunoassay card test for the detection of cannabinoid and cocaine metabolites in urine specimens. Results are available in about three minutes. The test kit costs approximately $12.00 per two-drug test, and there are no additional
Rapid, reliable, sensitive, qualitative, and quantitative methods using small urine volumes (0.2-0.5 mL) were developed primarily for confirmation of marijuana, cocaine, benzoylecgonine, ecgonine methyl ester, morphine, codeine, amphetamine, methamphetamine, and phencyclidine. Using capillary gas
A case is presented involving a young woman on several illicit drugs (heroin, cocaine and cannabis) as well as two medications and a solvent used for their anesthetic and narcotic properties: thiopental, ketamine and chloroform. This complex drug use was supported by hair analysis over a 10.5 cm
To drug-free urine specimens, we added the following drugs of abuse to give concentrations twice the cutoff value for positive test results: 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (9-carboxy-THC), oxazepam, secobarbital, morphine, benzoylecgonine, amphetamine, or phencyclidine (PCP). Visine
Testing for drugs of abuse in urine is commonplace in emergency departments and neonatal units. However, the clinical sensitivity of immunochemical screening methods is limited by the threshold concentrations used to distinguish between positive and negative specimens. Immunochemical screening
ELISAs are widely utilized in forensic drug analysis. A comparative assessment of microtiter plate assays for the detection of six common classes of drug in blood and urine is described.
ELISAs for opiates, methamphetamine, benzodiazepines, cocaine metabolite, phencyclidine (PCP), and
Drug abuse among college students is characterized by lower academic performance and long-term negative consequences. Screening to detect students at high risk of consuming drugs is of primary importance to insure early identification and appropriate levels of care. As a result, this study aimed to
A GC-MS method for simultaneous analysis of cocaine (COC), amphetamines (AMPs), opiates, cannabinoids and their metabolites in vitreous humor (VH) was developed and fully validated. VH samples were extracted using solid phase extraction and injected into the GC-MS, using a selected ion monitoring
Although the use of ethanol, marijuana, and other drugs may be detrimental to driving safety, this has been established by direct epidemiological evidence only for ethanol. In this study, the incidences of detection of ethanol (and other volatile substances), delta-9-tetrahydrocannabinol (THC),
Chromatographic separation of highly polar basic drugs with ideal ionspray mass spectrometry volatile mobile phases is a difficult challenge. A new quantification procedure was developed using hydrophilic interaction chromatography-mass spectrometry with turbo-ionspray ionization in the positive
An ultra-high-pressure liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method has been developed for the simultaneous quantification and confirmation of 11 basic/acidic illicit drugs and relevant metabolites in surface and urban wastewater at ng/L levels. The sample pre-treatment
The present paper describes a sensitive method developed in our laboratory for the simultaneous analysis of opiates (morphine, codeine and monoacetylmorphine), cocainis (cocaine and benzoylecgonine) and cannabinoids (delta 9-tetrahydrocannabinol and 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic
