Drug Monitoring Amphetamines with Confirmation Urine

Laboratory
Quest Diagnostics
Test code
39367
Specimen
Urine
Fasting
Not stated as required

What the laboratory says this test is for

The amphetamine class of drugs are traditionally classified as stimulants. Some members of the class (amphetamine) are prescribed for treatment of attention-deficit hyperactivity disorder (ADHD), to suppress appetite, and for narcolepsy. Other members of the class are considered drugs of abuse (methamphetamine, MDMA) with no accepted medical uses. The test is a screening assay using a homogeneous enzyme immunoassay method of analysis. Presumptive positive screen results are reflexed to a more specific and sensitive liquid chromatography mass spectroscopy (LC/MS/MS) test. Therapeutic urine drug monitoring of the amphetamines and their metabolites is important for ensuring compliance to treatment strategies, as well as ensuring non-diversion for illicit purposes. Urine or oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs. Use of serum/plasma should be limited to anuretic patients, or where a patient's clinical appearance does not coincide with their prescribed medications. No single monitoring approach provides adequate information about the pattern or dose of patient drug use. Safest prescribing habits should include a combination of tools and laboratory test results to correctly detect drug use patterns. Urine drug test results equal to or greater than cutoff are reported as positive and results less than cutoff are reported as negative. Quantitative values cannot be used to assess the drug dose, because the drug is extensively metabolized and excreted in the urine.

What the laboratory says this test is for

The amphetamine class of drugs are traditionally classified as stimulants. Some members of the class (amphetamine) are prescribed for treatment of attention-deficit hyperactivity disorder (ADHD), to suppress appetite, and for narcolepsy.

The test is a screening assay using a homogeneous enzyme immunoassay method of analysis. Presumptive positive screen results are reflexed to a more specific and sensitive liquid chromatography mass spectroscopy (LC/MS/MS) test. Additionally, if methamphetamine is confirmed by LC/MS/MS, an additional confirmation procedure will be done to determine the specific isomer that is present. Therapeutic urine drug monitoring of the amphetamines and their metabolites is important for ensuring compliance to treatment strategies, as well as ensuring non-diversion for illicit purposes. Urine or oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs.
