Screening Test. The initial test uses an immunoassay to determine levels of drugs or drug metabolites. The following initial cutoff levels shall be used when screening specimens to determine whether they are negative for these five (5) drugs or drug classes. Substance Initial Test Level (ng/ml) Marijuana Metabolites 50 Cocaine Metabolites 300 150 6-Acetylmorphine 10 Opiate Metabolites 2000 Phencyclidine 25 Amphetamines 1,000 500 MDMA/MDA/MDEA 500 These substances and test levels are subject to change by the Department of Transportation as advances in technology or other considerations warrant.
Screening Test. The initial screening test uses an Evidential Breath Testing (EBT) device, unless other testing methodologies or devices are mandated or agreed upon, to determine levels of alcohol. The following initial cutoff levels shall be used when screening breath samples to determine whether they are negative or positive for alcohol. Breath Alcohol Levels: Less than 0.02% BAC - Negative 0.02% BAC and above - Positive (Requires Confirmation Test)
Screening Test. The initial screening test uses an EBT device to determine levels of alcohol. The following initial cutoff levels shall be used when screening specimens to determine whether they are negative for alcohol: Breath Alcohol Levels Less than 0.04 - Negative 0.04 and above - Positive, requiring confirmatory testing.
Screening Test. A preliminary test. For a urine test it is an immunoassay or a thin-layer chromatography test which identifies the presence of a drug / metabolite in an individual’s system and which generally is 92-98% reliable. For measuring the amount of alcohol in a person’s system it is generally a certified breath or saliva test (although blood testing may be used when breath or saliva screenings cannot meet the necessary quality standards).
Screening Test. The initial test shall use an immunoassay to determine levels of drugs or drug metabolites. The following initial cutoff levels shall be used when screening specimens to determine whether they are negative for these five (5) drugs or drug classes: Substance Initial Test Level (ng/ml) Marijuana Metabolites 50 Cocaine Metabolites 300 Opiate Metabolites 300 Phencyclidine 25 Amphetamines 1,000 *25 ng/ml is immunoassay specific for free morphine Section 5. Confirmatory Test All specimens identified as positive on the initial test shall be confirmed using gas chromatography/mass spectrometry (GC/MS) techniques at the cutoff values listed. The following cutoff levels shall be used to confirm the presence of drugs or drug metabolites: Substance Confirmatory Test Level (ng/ml) Marijuana Metabolite (1) 15 Cocaine Metabolite (2) 150 Opiates: Morphine 300 Codeine 300 Phencyclidine 25 Amphetamines: Amphetamine 500 Methamphetamine 500
Screening Test. CONFIRMATION: Amphetamines 1000 ng/ml Amphetamine 500 ng/ml GC/MS Methamphetamine 500 ng/ml GC/MS (Specimen must also contain amphetamine at a concentration of greater than or equal to 200 ng/ml) Cocaine Metabolites 300 ng/ml 150 ng/ml GC/MS metabolite Opiate Metabolites 2000 ng/ml Morphine Morphine 2000 ng/ml GC/MS Codeine 2000 ng/ml GC/MS 6-acetylmorphine (6-AM) 10 ng/ml GC/MS (Test for 6-AM in the specimen. Conduct this test only when specimen contains morphine at a concentration greater than or equal to 2000 ng/ml.) Phencyclidine 25 ng/ml 25 ng/ml GC/MS Marijuana 50 ng/ml 15 ng/ml GC/MS Metabolites (Delta 9-THC) Ethyl Alcohol 0.04 g% 0.04 g%
Screening Test a. All breath alcohol testing shall be conducted through use of an Evidential Breath Testing (EBT) device, in accordance with FHA rules and DOT regulations.
Screening Test. The Chief or the Service-Safety Director may order any Employee of the Department to undergo a screening test whenever there is reasonable suspicion to believe an Employee has used, or is under the influence of illicit drugs, controlled substances, or an abuse of legal substances, or if the Employee is under the influence of alcohol while on duty.
Screening Test. A drug test will be conducted by the SDT team. A urine test kit will be used to test for the presence of illicit drugs (or their metabolites) in a person’s urine specimen. It covers common types of psychotropic substances abused by adolescent drug abusers in Hong Kong. As illustration, they may include:
Screening Test. (Screen or initial test) In alcohol testing, it is the initial procedure to determine if the driver has a prohibited concentration of alcohol in his or her system. In controlled substances testing, it is an immunoassay screen to eliminate "negative" urine specimens from further consideration.
