Specimen Collection Criteria

Collect: 50.0 mL random urine in a screw-capped container (preferred) or other sterile collection cup. (Minimum: 30 mL)

  • Refrigerate the specimen immediately after collection.
  • Record the exact time of specimen collection on the container or in the computer system.

Reference Range

Negative (Positive Cutoff: 500 ng/mL).

Test Methodology

Enzyme Immunoassay.

Interpretation

Concentrations of drugs and/or metabolite(s) detected in urine have not been correlated to drug levels in the bloodstream or with the degree of impairment. The presence of a drug and/or metabolite(s) in urine is only an indication of previous drug exposure.

Clinical Utility

Amphetamine and methamphetamine are central nervous system stimulants. They are usually administered orally or by intravenous injection.  These drugs are prescribed for treatment of obesity, narcolepsy, hypotension, attention deficit disorder, and hyperactivity disorder.  Because of their stimulant effects, the drugs are commonly sold illicitly and abused.  This assay is uses to aid in the diagnosis and treatment of amphetamine and/or methamphetamine use or abuse.
