Cutoff concentrations:

Methamphetamine: 100 ng/mL

Amphetamine: 100 ng/mL

3,4-Methylenedioxymethamphetamine (MDMA): 100 ng/mL

3,4-Methylenedioxy-N-ethylamphetamine (MDEA): 100 ng/mL

3,4-Methylenedioxyamphetamine (MDA): 100 ng/mL

Ephedrine: 100 ng/mL

Pseudoephedrine: 100 ng/mL

Phentermine: 100 ng/mL

Phencyclidine (PCP): 20 ng/mL

Methylphenidate: 20 ng/mL

Ritalinic acid: 100 ng/mL

Interpretation

If a stimulant or its corresponding metabolite is identified (present), it indicates that the patient has used the respective stimulant in the recent past (typically 1-3 days). The absence of the expected stimulant or its metabolites may indicate noncompliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, diluted or adulterated urine, or limitations of testing. The concentration of the drug must be greater than or equal to the cutoff to be reported as present. If a specific drug concentration is required, the laboratory must be contacted within 2 weeks of specimen collection/testing to request quantification by a second analytical technique at an additional charge.
